Question

我正在尝试编写FXCop规则来验证以下类型的代码，

namespace ClassTarget
{
    public class Class1
    {
        private static readonly Type DeclType = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType;
        public void StartWatchingForUpdates1()
        {
            using (new TraceGuard(DeclType,"StartWatchingForUpdates1"))
            {
                Console.Write("Test");
            }
        }

        /// <see cref="IAutomaticUpdaterBackendHelper.StopWatchingForUpdates"/>
        public void StopWatchingForUpdates2()
        {
            using (new TraceGuard(DeclType, "StopWatchingForUpdates2"))
            {

            }
        }

    }
}

这里我要验证方法名称和TraceGuard构造函数内部调用的字符串（使用（新的TraceGuard（DeclType，＆＃34; StopWatchingForUpdates2＆＃34;））是否相同。

我可以从我的FX警察规则中捕获Traceguard构造函数，但无法找到传递给它的第二个参数作为方法名称。

有人可以帮我吗？

感谢您的帮助，虽然这不是确切的解决方案，但它带我到了确切的一个。非常感谢!!
