你如何从Web服务中捕获抛出的SOAP异常？

Question

I throw a few soap exceptions in my web service successfully. I would like to catch the exceptions and access the string and ClientFaultCode that are called with the exception. Here is an example of one of my exceptions in the web service:

throw new SoapException("You lose the game.", SoapException.ClientFaultCode);

In my client, I try to run the method from the web service that may throw an exception, and I catch it. The problem is that my catch blocks don't do anything. See this example:

try
{
     service.StartGame();
}
catch
{
     // missing code goes here
}

How can I access the string and ClientFaultCode that are called with the thrown exception?

Answer 1

You may want to catch the specific exceptions.

try
{
     service.StartGame();
}
catch(SoapHeaderException)
{
// soap fault in the header e.g. auth failed
}
catch(SoapException x)
{
// general soap fault  and details in x.Message
}
catch(WebException)
{
// e.g. internet is down
}
catch(Exception)
{
// handles everything else
}

Answer 2

Catch the SoapException instance. That way you can access its information:

try {
     service.StartGame();
} catch (SoapException e)  {
    // The variable 'e' can access the exception's information.
}

Answer 3

catch (SoapException soapEx) 
{
  //Do something with soapEx
}
