1、Create a error class just like this
namespace TeamService.Projects
{
[DataContract]
public class ProjectServiceError
{
private string operation;
private string errorMessage;
[DataMember]
public String Operation
{
get { return operation; }
set { operation = value; }
}
[DataMember]
public String ErrorMessage
{
get { return errorMessage; }
set { errorMessage = value; }
}
}
}
2、通过FaultContract将其运用到Service Contract中制定的Operation上面
using TeamService.Data;
namespace TeamService
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IProjectService" in both code and config file together.
[ServiceContract]
public interface IProjectService
{
[OperationContract]
[FaultContract(typeof(TeamService.Projects.ProjectServiceError))]
int CreateMember(MyMember myMember);
3、在Service Implementation中以抛出Exception的方式植入这个
TeamService.Projects.ProjectServiceError对象
public int CreateMember(MyMember myMember)
{
if (myMember == null)
{
ProjectServiceError err = new ProjectServiceError();
err.Operation = " CreateMember";
err.ErrorMessage = "Input parameter is null.";
throw new FaultException(err.Operation + "：êo" + err.ErrorMessage);
}
后面还有代码，不写了
4、客户端调用
private void button1_Click(object sender, RoutedEventArgs e)
{
TeamClient.ProjectServiceReference.ProjectServiceClient sv = new ProjectServiceClient();
MyMember mb = null;
try
{
if (sv != null)
{
sv.CreateMember(mb);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
5、效果显示：
