I usually use the  ToString   method on exceptions to present the full exception information  including the inner stack trace  in text   catch  MyCustomException ex        Debug WriteLine ex ToString         Sample output   ConsoleApplication1 MyCustomException  some message      --- gt  System Exception  Oh noes     at ConsoleApplication1 SomeObject OtherMethod   in C  ConsoleApplication1 SomeObject cs line 24    at ConsoleApplication1 SomeObject  ctor   in C  ConsoleApplication1 SomeObject cs line 14    --- End of inner exception stack trace ---    at ConsoleApplication1 SomeObject  ctor   in C  ConsoleApplication1 SomeObject cs line 18    at ConsoleApplication1 Program DoSomething   in C  ConsoleApplication1 Program cs line 23    at ConsoleApplication1 Program Main String   args  in C  ConsoleApplication1 Program cs line 13

1  Create Method  If you pass your exception to the following function  it will give you all methods and details which are reasons of the exception    public string GetAllFootprints Exception x            var st   new StackTrace x  true           var frames   st GetFrames            var traceString   new StringBuilder             foreach  var frame in frames                        if  frame GetFileLineNumber    lt  1                  continue               traceString Append  File      frame GetFileName                 traceString Append    Method     frame GetMethod   Name               traceString Append    LineNumber      frame GetFileLineNumber                 traceString Append    -- gt                          return traceString ToString        2  Call Method  You can call the method like this   try          code part which you want to catch exception on it   catch Exception ex        Debug Writeline GetAllFootprints ex        3  Get the Result   File  c  MyProject Program cs  Method MyFunction  LineNumber  29  -- gt    File  c  MyProject Program cs  Method Main  LineNumber  16  -- gt
