In have created a Web Service which needs to be consumed by multiple environment (.Net,Java,Python..etc) hence ,I have used List<list> as an outparameter (with "OUT" keyword )in my Web service to return value. My question is Will all the application consuming my webserice able to get List as return value ? if not can anyone help me out in getting return values from asp.net webserive that will be consumed by multiple environment
public List<Customer> GetCustomers() { PR1Entities dc = new PR1Entities(); var q = (from x in dc.Customers select x).ToList(); return q; } (customer is a entity object)
Then I generate the proxy when I add the service.. and in the reference.cd it say
public wcf1.ServiceReference1.Customer[] GetCustomers() { return base.Channel.GetCustomers(); }
Suppose I have the string like String sample="{K,S},{T}". Then splitting with "," I need the output of the string array. The string array is having items {k,S}, {T}. how to split the above string with "," separated.
I am trying to return some data as json from an action method.
I have an employee object that looks like this:
public class Employee { public int EmployeeID {get; set;} public string FirstName {get; set;} public string LastName {get; set;} //Other irrelevant properties }
Then I have a view model as follows
public Class EmployeeViewModel { public Employee Supervisor{get; set;} public List<EmployeeViewModel> Employees }
I need to return a json object that looks exactly like this:
For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.
How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.
I am trying to create a dynamic table that is being built based on the value of a search text box. The Table will have probably 6 columns of 20(max) rows.
My problem is I can't figure out how to return the data from the web-service to the JS function in a way that will allow me to extract the data that I need.
I need to pass a random number from 1 to 100 from the client to a webservice, and then the webservice will subtract this number from the list of 100 numbers (say 1-100). Then, in the next call, the next random number will be subtracted from the rest 99 numbers and so on.
I need this to be done with AJAX. I don't know where the Array list should be held in the first place (would it be in the web service or in the code behind? ), and how this can be done?
A sample web service app I have been practicing with has two web methods: 1) HelloWorld -- which I can read the data from no problem - just a string 2) ClientData[] -- which returns an array of struct objects -- this is where I have the question.
Here is my instantiation of the webservice in my winform app for reading from HelloWorld
myWebSvc1.WebService1 s1 = new myWebSvc1.WebService1(); string y = s1.HelloWorld(); //--no problems so far here Console.WriteLine(y); //--but when I add the call to GetClientData() I have a problem List<ClientData> ls = new List<ClientData>(s1.GetClientData(3)); //--problem here
public struct ClientData { public String Name; public int ID; } [WebMethod(CacheDuration = 30, Description="Returns an array of Clients.")] public ClientData[] GetClientData(int Number) { ClientData [] Clients = null; if (Number > 0 && Number <= 10) { Clients = new ClientData[Number]; for (int i = 0; i < Number; i++) { Clients[i].Name = "Client " + i.ToString(); Clients[i].ID = i; } } return Clients; }
If I browse the .asmx file -- the sample xml returns the following if I enter 3 for GetClientData function param
From my winform app I get the following error messages when trying to add the GetClientData function call above --
Error 1 The best overloaded method match for 'System.Collections.Generic.List<DSS_2008.Form7.ClientData[]>.List(System.Collections.Generic.IEnumerable<DSS_2008.Form7.ClientData[]>)' has some invalid arguments
Error 2 Argument '1': cannot convert from 'DSS_2008.myWebSvc1.ClientData[]' to 'System.Collections.Generic.IEnumerable<DSS_2008.Form7.ClientData[]>'

Error 2 Argument '1': cannot convert from 'DSS_2008.myWebSvc1.ClientData[]' to 'int'
How can I fix this so that I can read the result into my winform app? //--sample web service

I have a web service that originally returned a string containing text formatted as XML. I was contacted by the programmer who is going to be consuming the web service, and he asked if I could make it "just XML" and not a string. I converted the web service so that it returns an XMLDocument object, and it seems to be returning data properly. I would just like to erify, however, that the XMLDocument object is what the other programmer was referring to when he said "just XML," and that the XMLDocument can be universally consumed by any programmer, regardless of his or her programming environment.
I am new to web service... I have created a simple web service to add a record to sql server by passing a parameter and returns true or false once done. It the same time, I want to return the customer_account_number value created on the sql server.. so basically I want to return the true and false and one (or more) additional values.
i have a data library dll and first is it possible to use it in webservice forexample i call it as using DataLibrary; then in web method i will use it like
public boolean MethodName(int a) { if(DataLibrary.Method(a)) return true; else return false; }
and also i have to tell my all data connections are in DataLibrary.dll
my second question is i will use webservice to communucate with flash i will send flash a DataSet but flash cant read DataSet so i have give it as XML right?
so how could i change my following method which returns dataset to return xml ?
I want to return an array of javascript objects from my asp.net asmx file. ie.
variable = [ { *value1*: 'value1',[code]....
I seem have been having trouble reaching this. I'd put this into code but I've been hacking away at it so much it'd probably do more harm than good in having this answered. Basically I am using a web service to find names as people type the name. I'd use a regular text file or something but its a huge database that's always changing - and don't worry I've indexed the names so searching can be a little snappier - but I would really prefer to stick with this method and just figure out how to get usable JSON back to javascript. I've seen a few that sort of attempt to describe how one would approach this but I honestly think microsofts articles are damn near unreadable.
EDIT: I'm using the $.ajax() function from jQuery - I've had it working but it seems like I was doing it in bad practice not returning and using actual JSON. Previously I'd take a string back and insert it into html to use the variable it set - very roundabout.
I am coding a classic .asmx web service. The method get data (as a string) from a server, then assign data to an object, then return that object. But I want to cache that object to a XML file for other request. It's because the data from server is not frequently change. Thus, after some minutes, I have to refresh the XML file. When I refresh XML file, I could write object to XML first, then return that object, but that approach maybe slowly.
How can I return the object for client first, then write this to XML file?
I have a requirement to build a simple ASP.NET web page which sends some parameters to a web service, and then displays the string which was returned. I'm a complete .NET newby and the only examples I can find seem really really complex. I just need something mega simple, but which an handle parameters being sent to the web service. Can anyone point me in the direction of a simple bit of C# which will do this with no frills or fuss?
I can fill and then return typed dataset from a web method, but applying these steps by using Typed Datatable instead of Typed Dataset I cannot return filled typed dataTable. So, is it possible to return typed dataTable from a web method? If yes, how can I do this?
I shall give a little bit information about my project. There is 3 project in my solution. I) Presentation Layer (WinForm), II) Business Layer (Web Service) , III) Data Access Layer (Win form project type)... The problem is that;
I use 2 seperate methods. 1st is FillTable() which fill a datatable in my Typed Dataset in Data Access layer. The 2nd isGetTable() which should return typed datatable filled by FillTable() method. I try these methods and FillTable() methods (goes from I. layer to II. Layer and then III. layer) fills a datatable properly and after that I can return this datatable by calling GetTable() method from Typed Dataset (in III. layer) to WebService. I have tested the rows count of returning datatable and there is no problem up to WebService. But even after returning this typed datatable from WebService the table comes to Presentation Layer empty. So, there is a problem returning filled typed datatable from WebService to WebForm (from II. layer to I. layer).
On the other hand, if I try this methods by returning Typed Dataset instead of Typed Datatable, I can return properly with a filled datatable in Typed Dataset. But, I relly do not want to return a huge filled dataset which may contain 15 tables instead of one datatable. My questions;
1) Is there any logical approach mistake on my Layer Architecture?
2) What should I do in order to get a Typed Datatable from Web Service (II. Layer of my project)?
I have been given access to a web service that I can use to pull valuable data for my company. The issue I am having is I don't know where to begin writing out the returned values. I am using an asp.net VB web file to connect to the web service and call the wanted procedures. I have added the web service as an web reference in my project, other than that I am stuck. Here is what I have so far;
[Code]....
So basically I am writing out an array but it comes out like this;
[Code]....
This is not the expected the return but from what I understand the VeroWebService.SaleModel is like the parent xml/SOAP element.The expected return is more like;
Function inside the service simply returns string separated by some delimitor. This string is then used by JS function to assign to a jQuery datatable. Is there a maximum limit on size of this string? I have about 2000 rows with 6 columns each. I get an error (failed handle) when I return them all. But if I do only top 500, it works fine.Is there any size limitation?
