Introduction

WCF (Windows Communication Foundation)-exception handling: general Exception handling, FaultException and FaultException throwing and handling, using IErrorHandler to handle exceptions.

Here is the third exception: throwing and handling of FaultException

1. Strongly typed an SOP error class, which needs to be passed with [DataContract] / error message entity class (for error contract FaultContract) / [DataContract] public class FaultMessage {/ DataMember] public string Message {get; set;} / error code / [DataMember] public int ErrorCode {get; set Specify the error type [ServiceContract] public interface IHello {[OperationContract] [FaultContract (typeof (FaultMessage))] void HelloFaultExceptionGeneric () with [FaultContract] error contract in the operation agreement. 3. In the implementation code, define a method that can throw an exception of FaultException / Hello class / public class Hello: IHello {/ throw FaultException exception / public void HelloFaultExceptionGeneric () {throw new FaultException (new FaultMessage {Message = "throw FaultException exception", ErrorCode =-1}, "for testing FaultException") Fourth, the exception of FaultException can be caught in the client. FaultMessage is accessed with the Detail attribute. Protected void btnHelloFaultExceptionGeneric_Click (object sender, EventArgs e) {ExceptionService.HelloClient proxy = new ExceptionService.HelloClient (); try {proxy.HelloFaultExceptionGeneric ();} catch (System.ServiceModel.FaultException ex) {lblMsg.Text = string.Format ("error Code: {0}; error message: {1} Error reasons: {2} ", ex.Detail.ErrorCode.ToString (), ex.Detail.Message, ex.Reason.ToString ();} finally {proxy.Close ();}} so far, I believe you have a deeper understanding of" what is the exception handling of WCF ".
