调试器未输入自定义属性类 [英] Debugger is not entering custom attribute class

问题描述

这是用于桌面的C＃WPF应用程序。我已经创建了一个自定义属性类，但在调试中它从来没有进入过。我是否需要向此类添加其他内容？

This is a C# WPF application for a desktop. I've created a custom attribute class but in debug it never goes in there. Do I need to add something else to this class?

[AttributeUsage(AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class Authentication : Attribute, IPrincipal
{
    public Authentication(string id)
    {
        throw new NotImplementedException();
    }

    public IIdentity Identity { get; private set; }

    public bool IsInRole(string role)
    {
        throw new NotImplementedException();
    }

}

方法是：

    [Authentication(SecurityConstants.DataEntrySupervisor)]
    [Authentication(SecurityConstants.DataVerificationClerk)]
    public void Submit(EventObject eventObject)
    {//////////}

推荐答案

运行时不会以任何方式调用属性。直到您进行反思之后，它才可能被实例化。

An attribute is not called by the runtime in any way. It probably does not even get instanciated until you poke around with reflection.

您可以查看 SecurityAttribute 。
