传递方法名称作为参数 [英] Passing a method's name as a parameter

问题描述

private void Method1()
{
    //Do something
    Log("Something","Method1");
}

private void Method2()
{
    //Do something
    Log("Something","Method2");
}

private void Log(string message, string method)
{
    //Write to a log file
    Trace.TraceInformation(message + "happened at " + method);
}

我有几种方法，例如上面的Method1和Method2，我想以某种方式将方法的名称作为参数传递，而无需手动编辑代码.

I have several methods like Method1 and Method2 above, and i would like some way pass the method's name as a parameter, without manually editing the code.

有可能吗?

推荐答案

乔恩·斯凯特(Jon Skeet)的出色回答.

Excellent answer from Jon Skeet.

但是，如果您不使用.NET 4.5，则可以尝试reflection.你怎么应该知道reflection must be used only when it is absolutely necessary. Do not over-use it for the sake of using it.

However, if you don't use .NET 4.5 , you can try reflection. How ever you should know that reflection must be used only when it is absolutely necessary. Do not over-use it for the sake of using it.

回来， 您可以做类似的事情，

Coming back, You could do something like,

 using System.Reflection; //include Reflection namespace

 Console.WriteLine(MethodBase.GetCurrentMethod().Name) //Get the method-name of the current method

在您的情况下，如下所示，

In your case, it would be like below,

private void Method1()
{
    //Do something
    Log("Something", System.Reflection.MethodBase.GetCurrentMethod().Name);
}

private void Method2()
{
    //Do something
    Log("Something", System.Reflection.MethodBase.GetCurrentMethod().Name);
}

private void Log(string message, string method)
{
    //Write to a log file
    Trace.TraceInformation(message + "happened at " + method);
}

根据@Jon Skeet的以下评论，如果您想要.Net 4.5那种精美而整洁的实现，请查看Micrsoft.Bcl NUGET软件包.
