Handling WCF Exceptions from ASPX page

If a WCF method fails when you call it from your ASPX page you might want to save the exception details somewhere, in a database table or in a text/xml file, or output it in the browser. But how will you get the details of the WCF exception in your ASP.NET code-behind class? You may find the following code snippet useful.

string serviceStackTrace = "";

//WCF method call
catch(Exception ex)
if (ex is FaultException)
serviceStackTrace = ((System.ServiceModel.FaultException)(ex)).Detail.StackTrace;
else if (ex is System.ServiceModel.CommunicationException)
serviceStackTrace = ex.StackTrace;

//Do whatever you want to do with serviceStackTrace
