C# - Test A Returned Array Contains At Least One Value With A Certain Property Value?
Oct 18, 2010
I have a method I wish to test:
public Cars[] GetCars();
I want to test that the array returned by this method contains at least one car which is of type "Mustang".
How would I actually do this?
Currently I have code like:
[Test]
public void GetCars_ReturnsMustangs()
{
Cars[] cars = GetCars();
foreach(Car car in cars)
{
Assert.IsTrue(Car.Type == "Mustang");
}
}
While this works as a test as far as I can tell I'm aware it's not a good idea to put loops inside the test?

I am developing an active x control for IE which is invoked through javascript. The active x control is developed in visual basic and it an array of strings. How will I use this array of strings in javscript.
Eg :-
var a = new Array()
a = objActiveX.GetArray(); // call to active x returns array of string, how will I loop through this in javascript. The above line does not work.I want to loop through each string in javascript.

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
<?xml version="1.0" encoding="utf-8" ?>
- <ArrayOfClientData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://codeproject.com/webservices/">
- <ClientData>
<Name>Client 0</Name>
<ID>0</ID>
</ClientData>
- <ClientData>
<Name>Client 1</Name>
<ID>1</ID>
</ClientData>
- <ClientData>
<Name>Client 2</Name>
<ID>2</ID>
</ClientData>
</ArrayOfClientData>
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?

I am wondering if it's possible to send an array of strings to a tag's property
<SampleTag:Form
runat="server"
ID="sampleform1"
Items={item1,item2,item3,item4}
>
</SampleTag:Form>
This doesn't work since it sends "{item1,item2,item3,item4}" as a string to the class.

As what other member said in this community, the data assign a public variable may be shared among users, therefore, how am be able to declare a property that will accept an array of values using List<string>? The variable will be use in about fifteen pages...if I am going to declare this on each of the page, this will result to difficulty in maintaining the code of my program.

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:
{id: 1, name: John, children: [
{id: 1, name: Joe, children: []},
{id: 1, name: Rob, children: []}
]}
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'll use Customer and Addresses as an example rather than explain my real objects. Say I have a repeater bound to a collection of Customers and one of the properties of Customer is an array of addresses. How do I bind to the addresses property? I don't even need to display this information I just want to use it in the Repeaters ItemDataBound event. So I tried to bind a hiddenField to the addresses property but all I get for every customer in the hiddenfields value is an empty array of addresses.

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.

I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

i have to do some message exchange with a 3rd party (in a website).When the client posts a page, i start the message exchange. When that doesn't succeed for some reason, i report this to the client by rendering the page with a message.On the background, in a separate thread, i start a process to send abort messages to the 3rd party. I can't do this while the user is waiting for the page to come back, because it might take a few minutes.But in a test project, the test ends when the message to the 3rd party is sent, and after the new thread is started. But it seems that the new thread also ends, when the test is done.
Is that normal behaviour?I do start the thread in a new class with a reference to 2 objects from the class which tries to send the message in the first place, may that be a problem?EDIT: it keeps running when the whole process is started in IIS

So what I'm trying to accomplish is this
[Code]....
The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.

Can anyone add a complete input about how to create Parent Property with multiple child properties or in short nested properties.
Example: Style tag: which has properties like font, color, display... etc? which accept objects and its value.
[code]....
As soon as Rainbow property is typed, user should get intellisense for list of number of colors. Then accordingly user can select list of those colors and assign a value to them.

Is there any difference between accessing a property that has a backing field
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
versus an auto-property?
public int Id { get; set; }
The reason I'm asking is that when letting ReSharper convert a property into an auto property it seems to scan my entire solution, or at least all aspx-files.
I can't see any reason why there should be any difference between the two from outside the class. Is there?

In the Web.Config we have a timeout property. Ex:
<authentication mode="Forms">
<forms loginUrl="~/Login.aspx" timeout="2880"/>
</authentication>
When loggin in, we can specify a ticket expiry date. Ex:
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1, id.ToString(), DateTime.Now, expiryDate, true,
securityToken, FormsAuthentication.FormsCookiePath);
Why there's two places where I can set expiration info about forms-authentication? What's the difference between them? What has more relevance?

I have a masterpage that contains all the javascript and inside the content control, there is a link that calls a javascript function and I want to pass the id once it's rendered differently by the server.
<asp:TextBox ID="txtstart" runat="server" Width="20%"></asp:TextBox>
<a title="Pick Date from Calendar" onclick="calendarPicker('<% txtstart.ClientId %>');" href="javascript:void(0);">
However, I keep getting this error:
Property access must assign to the property or use its value.
How would I be able to accomplish this?
