Create own client importer

Hi,

when I add a service reference, Visual Studio creates the file 'Reference.cs'. Visual Studio implements the functions of a WCF service with following code:

public void <Functionname> {
return base.Channel.<Functionname>();
}

Now my question. Is it possible that the importer create following code automatically?

public void <Functionname> {
try
{
return base.Channel.<Functionname>();
}
catch (FaultException ex)
{
// Do anything
throw new MyException();
}
}

Regards

Is GetDSRequest a [MessageContract] class with no members? If so, then it's equivalent to a parameterless method. I assume that GetDSResponseGetDSResult is also a [MessageContract] class with a DataSet parameter. There area fewtransformations that the Add Service Reference dialog (or svcutil.exe) does to "clean-up" the generated code, but they shouldn't affect the semantics of the type: it will still be usable as a way to send requests to the service.

You won't be able to change the importer used by the "Add Service Reference" dialog, but you can create your own. Take a look at my post at thread http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/14100bbb-9a73-4bcc-b513-088bb2e5ec65, and you'll see a way to do that. After having the code in memory (CodeDom), you can traverse it andchange the function you need.

Hi,

thank you for your answer. Now I can change the functions. But codedom produce incorrect code, when I add a function who returns a dataset.
I added following function to the service in your sample:

[OperationContract]
System.Data.DataSet GetDS();

Hope, you can help me.

What is the problem with the code produced by CodeDom? That function seems ok by me...

Carlos Figueira

CodeDom generate following code for the function 'GetDS':

[System.ComponentModel.

EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]

GetDSResponse ITest.GetDS(GetDSRequest request) {

return base.Channel.GetDS(request);

}

public GetDSResponseGetDSResult GetDS() {

GetDSRequest inValue = new GetDSRequest();

GetDSResponse retVal = ((ITest)(this)).GetDS(inValue);

return retVal.GetDSResult;

}

When I create the service reference in VisualStudio, following code is generated for the function 'GetDS':

publicSystem.Data.DataSet GetDS() {

return base.Channel.GetDS();

}

Does the function created by CodeDom work? It's possible that the ASR dialog does some optimization (i.e., for a parameterless method), but if those two functions are equivalent, then it shouldn't be an issue, right?

Carlos Figueira

I believe, the reason is the return type 'System.Data.DataSet' and not a parameterless method.
