如何找到调用当前方法的方法？
I need a way to know the name of calling methods in C#.
我需要一种方法来知道 C# 中调用方法的名称。
For instance:
例如：
private void doSomething()
{
// I need to know who is calling me? (method1 or method2).
// do something pursuant to who is calling you?
}
private void method1()
{
doSomething();
}
private void method2()
{
doSomething();
}

using System.Diagnostics;
// get call stack
StackTrace stackTrace = new StackTrace();
// get calling method name
Console.WriteLine(stackTrace.GetFrame(1).GetMethod().Name);

You almost certainly don't want to do this. A caller should never know who is calling it. Instead, the difference between the two callers should be abstracted into a parameter, and passed into the method being called:
你几乎肯定不想这样做。调用者永远不应该知道是谁在调用它。相反，两个调用者之间的差异应该抽象为一个参数，并传递到被调用的方法中：
private void doSomething(bool doItThisWay)
{
if (doItThisWay)
{
// Do it one way
}
else
{
// Do it the other way
}
}
private void method1()
{
doSomething(true);
}
private void method2()
{
doSomething(false);
}
This way, if you add a method3, it can either doSomething one way or the other, and doSomething won't care.
这样，如果您添加方法 3，它可以以一种方式或另一种方式 doSomething，doSomething 不会在意。
