次のコード例は、サービスからスローされた FaultException オブジェクトをキャッチして処理する try/catch ブロックの使用方法を示しています。これは、サービス アプリケーションでデバッグがオンの場合にしばしば使用される方法です。
using System;
using System.ServiceModel;
using System.ServiceModel.Channels;
using Microsoft.WCF.Documentation;
public class Client
{
public static void Main()
{
// Picks up configuration from the configuration file.
SampleServiceClient wcfClient = new SampleServiceClient();
try
{
// Making calls.
Console.WriteLine("Enter the greeting to send: ");
string greeting = Console.ReadLine();
Console.WriteLine("The service responded: " + wcfClient.SampleMethod(greeting));
Console.WriteLine("Press ENTER to exit:");
Console.ReadLine();
}
catch (TimeoutException timeProblem)
{
Console.WriteLine("The service operation timed out. " + timeProblem.Message);
wcfClient.Abort();
Console.ReadLine();
}
// Catch the contractually specified SOAP fault raised here as an exception.
catch (FaultException<GreetingFault> greetingFault)
{
Console.WriteLine(greetingFault.Detail.Message);
Console.Read();
wcfClient.Abort();
}
// Catch unrecognized faults. This handler receives exceptions thrown by WCF
// services when ServiceDebugBehavior.IncludeExceptionDetailInFaults
// is set to true.
catch (FaultException faultEx)
{
Console.WriteLine("An unknown exception was received. "
+ faultEx.Message
+ faultEx.StackTrace
);
Console.Read();
wcfClient.Abort();
}
// Standard communication fault handler.
catch (CommunicationException commProblem)
{
Console.WriteLine("There was a communication problem. " + commProblem.Message + commProblem.StackTrace);
Console.Read();
wcfClient.Abort();
}
}
}
