c# 错误立即使程序崩溃

Question

//interface
[OperationContract]
[FaultContract(typeof(UserManagementFault))]
void AddUser(User user);

//class implements interface
public void AddUser(User user)
{
    //throw faultException (instant crash)
    throw new FaultException<UserManagementFault>(new UserManagementFault("User Excists"),
        new FaultReason("User Excists"));
}

//fault
[DataContract]
public class UserManagementFault
{
    private string _message;

    public UserManagementFault(string message)
    {
        _message = message;
    }

    [DataMember]
    public string Message { get { return _message; } set { _message = value; } }
}


//method invoker
try {
    AddUser();
} catch(FaultException<UserManagementFault>) {

}

throw new FaultException 行执行时程序崩溃，但我希望程序跳转到代码底部的catch 部分。我做错了什么？？

编辑：我注意到 Visual Studio 正在暂停程序，但是当我按下“继续”时，程序进入了 catch 块...奇怪

Answer 1

您的自定义异常代码中似乎有问题。我也会添加一个一般例外以查看发生了什么

try {
    AddUser();
} catch(FaultException<UserManagementFault>) {

}
catch(Exception ex) {

}

c# fault instantly crashes program

c#

try-catch
