Question

An exception occurs on line

ModifyProfileResp resp = BFGlobal.modifyProfile(req);

INTERNAL_ERROR, SoapHeaderException was unhandled

 Error: System.Exception._COMPlusExceptionCode -532462766,

This code basically updates the users information on a web service through a call I made.

    public ModifyProfileResp ModifyProfile(string n_homeTelephone)
    {
        try
        {
            // Get Login Resp
            LoginResp loginResp = LoginToBetfair("username", "password");

            // Make a BFGS instance
            BFGlobal = new BFGlobalService();

            // Set up the request in [req]
            ModifyProfileReq req = new ModifyProfileReq();
            req.header = new APIRequestHeader();
            req.header.sessionToken = loginResp.header.sessionToken;
            req.homeTelephone = n_homeTelephone;


            // Set up the response in [resp]
            // Here is where Im getting thrown an exception..
            ModifyProfileResp resp = BFGlobal.modifyProfile(req); // <-- Here Im getting thrown an exception

            // return [resp] - which is the response from the call
            // Just trying to print out errror codes
            string mec = resp.minorErrorCode.ToString();
            string ec = resp.errorCode.ToString();

            return resp;
        }
        catch (Exception)
        {

            throw;
        }

Pretty straightforward, make the request header, call the response, pass in the req and I should get some data back, but I keep getting thrown a exception on this line.

Any ideas on how to go about this?

Answer 1

First,

don’t do this:

catch (Exception)
{   
    throw;
}

It’s pointless. If you don’t have the catch the exception will automatically get thrown up a level, which is what you’re doing with throw. Further, if you can’t do something with the exception (like retry the request) you’re probably better off letting the exception bubble up.

Second, try something like this:

catch (SoapHeaderException ex)
{
    Debug.WriteLine(ex.Message);
}

This will catch the specific exception that you’re dealing with. Further, set a breakpoint here on the Debug statement. You can then browse the details of the exception. You’ll be able to see the stacktrace, inner exceptions and any other data that the thrower of the SoapHeaderException might want you to see.

This information can often be useful when you’re debugging, for example, it could say “You forgot to initialize the flux capacitor.”
