Example

[Visual Basic] 
Dim myDiscoFile As String = "http://localhost/MathService_vb.vsdisco"
Dim myUrlKey As String = "http://localhost/MathService_vb.asmx?wsdl"
Dim myDiscoveryClientProtocol As New DiscoveryClientProtocol()

' Get the discovery document.
Dim myDiscoveryDocument As DiscoveryDocument = myDiscoveryClientProtocol.Discover(myDiscoFile)
Dim myEnumerator As IEnumerator = myDiscoveryDocument.References.GetEnumerator()
While myEnumerator.MoveNext()
  Dim myContractReference As ContractReference = CType(myEnumerator.Current, ContractReference)
   
  ' Get the DiscoveryClientProtocol from the ContractReference.
   myDiscoveryClientProtocol = myContractReference.ClientProtocol
   myDiscoveryClientProtocol.ResolveAll()

   Dim myExceptionDictionary As DiscoveryExceptionDictionary = myDiscoveryClientProtocol.Errors

   If myExceptionDictionary.Contains(myUrlKey) Then
      Console.WriteLine("System generated exceptions.")
      
      ' Get the exception from the DiscoveryExceptionDictionary.
      Dim myException As Exception = myExceptionDictionary(myUrlKey)
      
      Console.WriteLine(" Source : " & myException.Source)
      Console.WriteLine(" Exception : " & myException.Message)
      Console.WriteLine()
   End If
End While

[C#] 
string myDiscoFile = "http://localhost/MathService_cs.vsdisco";
string myUrlKey = "http://localhost/MathService_cs.asmx?wsdl";
DiscoveryClientProtocol myDiscoveryClientProtocol = 
      new DiscoveryClientProtocol();

// Get the discovery document.
DiscoveryDocument myDiscoveryDocument = 
   myDiscoveryClientProtocol.Discover(myDiscoFile);
IEnumerator myEnumerator = 
      myDiscoveryDocument.References.GetEnumerator();
while ( myEnumerator.MoveNext() )
{
   ContractReference myContractReference =
      (ContractReference)myEnumerator.Current;

   // Get the DiscoveryClientProtocol from the ContractReference.
   myDiscoveryClientProtocol = myContractReference.ClientProtocol;
   myDiscoveryClientProtocol.ResolveAll();

   DiscoveryExceptionDictionary myExceptionDictionary 
      = myDiscoveryClientProtocol.Errors;

   if (myExceptionDictionary.Contains(myUrlKey))
   {
      Console.WriteLine("System generated exceptions.");

      // Get the exception from the DiscoveryExceptionDictionary.
      Exception myException = myExceptionDictionary[myUrlKey];

      Console.WriteLine(" Source : " + myException.Source);
      Console.WriteLine(" Exception : " + myException.Message);
   }
}
