使用 FaultException 抛出用户友好的消息
你可以处理异常并抛出一个最友好的消息,例如’Unavailable service’抛出 FaultException:
try
{
// your service logic here
}
catch (Exception ex)
{
// You can do something here, like log the original exception
throw new FaultException("There was a problem processing your request");
}
在你的客户端中,你可以轻松获取消息:
try
{
// call the service
}
catch (FaultException faultEx)
{
var errorMessage = faultEx.Message;
// do something with error message
}
你可以将处理的异常与其他异常区分开来,例如网络错误,在代码中添加其他捕获:
try
{
// call the service
}
catch (FaultException faultEx)
{
var errorMessage = faultEx.Message;
// do something with error message
}
catch (CommunicationException commProblem)
{
// Handle the communication error, like trying another endpoint service or logging
}
