WCF / ASMX :: Webservice Custom Objects As Input Parameters?
Nov 9, 2010
I have a fundamental question to ask about web services. I'm currently writing a service that has custom classes (lots of them). Let's say a car is one example. For some reason I was thinking that the service should expose these objects. However once I created a site to consume the service, it looks as though the classes are not meant to be exposed. It looks like the best practice is to take in a string which may be xml or not and convert that string into the object in the service code.(especially for error handling or input validation)
For example, if I had the web method:
[WebMethod]
public car getCar(int carId)
{
//code here to return car object
}
This will take a car ID and return a car object. It also shows all the elements in the SOAP request and response objects (as well as the WSDL) which can be to external developers. However, when trying to consume the service from a website (or reference it in my code), I then need access to the Car class (which implies i need to expose it through the services as well?).

I have a ASP.NET webservice which is called by a Java client. The client sends a SOAP message as input but the problem is that it never reaches my webservice method. I always get null as input. I used TraceListener and saw this warning which may cause the problem:
The element was not expected in this context: <ListenerInput>..</ListenerInput>. Expected elements: http://client.ns.url/:ListenerInput.
This is what the client sends:
<?xml version="1.0" encoding="utf-8"?>
<S:Envelope xmlns:S = "http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>[code].....

i am working in the webservice project. I have one project when i run it then shows the text box for parameters and return the result after passing the parameters.
But another webservice does not allow me to enter the paramerters when execute then list of methods displayed and then show the soap xml when click at any method.
what difference found in both webserivces are Excuting-one that have the Text boxes: Test: "To test the operation using the HTTP POST protocol, click the 'Invoke' button."
2nd One Not provide the parameter text boxes: Test: "The test form is only available for methods with primitive types as parameters"
Dont know how to fix that. Because i want to debug the webservice and as i am unable to provide the parameter then how can i fix it.
how can i pass the parameters in the 2nd webservice as it has different information mentioned above.

I'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?

What I'm trying to do is rather basic, but I might have my facts mixed up. I have a details page that has a custom class as it's Model. The custom class uses 2 custom objects with yet another custom object a property of one of the 2. The details page outputs a fair amount of information, but allows the user to post a comment. When the user clicks the post button, the page gets posted to a Details action that looks something like this:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Details(VideoDetailModel vidAndComment) { ....}
[Code]....
The only fields on the form that is posted are CommentText and VideoId. Here is what the VideoDetailModel looks like.
public class VideoDetailModel
{
public VideoDetailModel()
{
[Code]....
I suppose if I added more form fields for the properties I need, they would get posted, but I only need 1 form entry field for the CommentText. If I could get the same Model objects value that were sent to the page to post with the page, it looks like the solution is rather simple. I think using the RenderPartial in the middle of a form is problematic somehow to how the form gets written in html. I can't really put my finger on why things went bonkers, but if I do my RenderPartials before my form and then begin my form with the text entry field and the hidden VideoId, the default ModelBinder works just fine. I was beginning the form, writing the hidden VideoId, rendering several partial views, create my CommentText field, and then closed the form out. The CommentText field would get bound just fine. The hidden VideoId would not. Maybe I missed a rule somewhere about using RenderPartial.
For completeness, the partial view I was rendering took a Comment object and just wrote out it's CommentText data. Several of these objects would exist for a single Video object. All of this data was in a custom type and passed into the View (the main view) as it's Model. This partial view did not have a form and did not have any data entry fields.

I have to save data into different C# objects based on the input.
Based on the value of "productChoice" my program should save data to the corresponding class.
For example :if productChoice = "auto" then the data shoud be set to AutoDataprefill object.
if productChoice = "vehicle" then the data shoud be set to VehicleMileage object.
My order class :
public class Order
{
public Products products {get;set;}
} [code]...
Here is my code to create an instance of "order" and save data to corresponding objects:
CLUEAuto.Personal.BusinessEntities.Order nwOrder = new CLUEAuto.Personal.BusinessEntities.Order
{
products = new CLUEAuto.Personal.BusinessEntities.Products
{
products = new CLUEAuto.Personal.BusinessEntities.productChoiceType [code]..

I have spent a couple of days on this one. I have an ASP.NET website that has Linkbuttons on
the Default.aspx page.. I added a WebService to the Website because later on the WebService will
subscribe to a Provider(Feed) of News, Sports and Weather and things like that. So when a Linkbutton
on the Default.aspx page is clicked it will connect to the link in the WebService which will load the News,
Sports or Weather onto the Default.aspx web page.
The problem is I can't get the LinkButton to execute the Link in the WebService. The link will call the page up
to where you see all of the Web References. But then if you want to execute one of those references you
have to click its link and the Invoke button that will follow. My questioh is how can the link on my Default.aspx
page execute the link in the WebService. Now I changed the LinkButton into an <a href> but I still can't execute
the link in the WebServices. I always use www.Microsoft.com as the link when testing and I wasn't sure about the return type
so I put "void" for an HTTPRequest, so below is the link from the Default.aspx web page and below that is he asmx file:

I try to add this webmethod with a custom contol like this
[Code]....
I don't get any error but when I test
[Code]....
Then I get the error
Fout: 'DavyQuyo.Text.Encoding' is empty of no object.
I really have to know how I can add the service from my custom control in a dll into my scriptmanager so I can call it with javascript.

I have a webservice method which needs to accept SOAP as input parameter. I've worked webservices between .NET clients but I've never worked using raw SOAP so I don't know what to do. The format of the input like this:
<?xml version="1.0" encoding="utf-8"?>
<S:Envelope xmlns:S = "[URL]/">
<S:Body>
<ns2:RemoteService xmlns:ns2 = "some.ns.url">
<RemoteServiceInput>
<param1>123</param1>
<param2>Asd Qwe</param2>
<param3 xsi:nil = "true" xmlns:xsi = "[URL]"/>
</RemoteServiceInput>
</ns2:RemoteService >
</S:Body>
</S:Envelope>
How should my method input be to accept this SOAP as parameter?

I am always thinking about validation in any kind on the webpage (PHP or ASP, it doesn't matter), but never find a good and accurate answer. For example, a I have some GET-Parameter, which defines a SQL query like DESC oder ASC. (SQL-Injection?) Or I have a comment-function for user, where the data is also saved in a database.
Is it enought to check for HTML-tags inside the data? Should the validation done before adding it to the database or showing it on the page? I am searching for the ToDo's which should be always performed with any data given from "outside".

I was looking for an asp.net webservice that uses .net 4.0 but everytime I choose 4.0 the webservice choice goes away.Someone suggested to me that maybe they(MS) want you to use WCF instead. I don't know much about it but he said they are like webservices but better. So anyone got a comparisons guide?

I have several VB.NET functions which pass and receive values from executed stored procedures using parameters. However, the latest method I am using seems to be a little too specific on the datatype and data length of the parameters for my liking (i.e.
LogActivityCommand.Parameters.Add("@strErrSource", SqlDbType.NVarChar, 300).Value = strErrSource). For example:
[code]....
If I end up changing the datatype and data length properties of the variables in my SQL stored procedures in the future, I am going to have to re-visit my VB code too and alter the parameter settings here as well.

I have an existing web application that uses EF and POCO objects. I want to improve the client experience by exposing some of my objects through WCF(JSON). I have this working fine but where I am unsure is how to handle derived objects(not sure if that is the correct term) or IEnumerable anonymous objects if you will.
Let's say I have 3 tables structured like so:
Templates
ID
Template
Groups
ID
Group
Instances
ID
TemplateID
GroupID
This is obviously a one-to-many type relationship. I have my navigation properties setup correctly and getting strongly typed object properties works great. However, how do I send serialized anonymous type object(s) over the wire. Like an object that sends all instances that are equal to groupid=1 and include the names of the template and the object.Am I missing something or do I have to create another class object for WCF that would look like this:
WCF Object
InstanceID
TemplateID
TemplateName
GroupID
GroupName
I guess I could alter my tables to account for this but that seems wrong too. I know that IEnumerable objects can't be serialized and I know that throw away objects are probably not the way to go either. I want to do this the right way but I am not sure how to go about it.
