If the WebService throws an Exception my Client app always get's a SoapException instead of http://stackoverflow.com/questions/2791951/web-service-exception-handling the "real" Exception. Here's a demo: [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [System.ComponentModel.ToolboxItem(false)] public class Service1 : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { throw new IndexOutOfRangeException("just a demo exception"); } } Now, on the client side, I want to be able to handle different exceptions in a different way. try { ServiceReference1.Service1SoapClient client = new ServiceReference1.Service1SoapClient(); Button1.Text = client.HelloWorld(); } catch (IndexOutOfRangeException ex) { // I know how to handle IndexOutOfRangeException // but this block is never reached } catch (MyOwnException ex) { // I know how to handle MyOwnException // but this block is never reached } catch (System.ServiceModel.FaultException ex) { // I always end in this block } But that does not work because I always get a "System.ServiceModel.FaultException" and I can only figure out the "real" exception by parsing the Exception's message property: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.IndexOutOfRangeException: just a demo\n at SoapExceptionTest.Service1.Service1.HelloWorld() in ... --- End of inner exception stack tra

In distributed computing, applications are designed as services that run on a server. Clients access these services through a programmable interface. When there is an exception during the execution of the Web service, the Web service should error handling not only capture the exceptions, but also communicate the exception back to the consumers of the Web service. Because Web services provide a platform-independent of way of leveraging a specific functionality, the exceptions that occur in the Web Services must also be communicated in a platform-independent manner. To accomplish this, you need to make sure that the exceptions raised from the Web services are compliant error handling in with the SOAP specification. In this article, we will understand how to raise exceptions from a Web service by using the SoapException object that provides an industry-standard way of representing a SOAP Fault. We will also see how to handle this exception from the Web service consumer application. Introduction An exception is any error condition or unexpected behavior encountered by an executing program. Exceptions can occur due to a number of reasons such as fault in your code, operating system resources not being available, unexpected conditions in the common language runtime, and so on. While your application can recover from some of these conditions, most of the runtime exceptions are irrecoverable. In that case, you need an effective way of handling those exceptions and informing the callers of the exception of the same. Using Structured Exceptions Handling to Handle Exceptions The crux of the exception handling support in a .NET Web service is provided by the try...catch...finally statement. The try keyword precedes a block of normal processing code that may throw an exception. The catch keyword precedes a block of exception handling code. The finally keyword precedes a block of co
