在匿名方法中使用 MethodInfo.GetCurrentMethod()

发布于 2024-10-12 16:07:55 字数 260 浏览 4 评论 0原文

public static void Main(string[] args)
{
    Action a = () => Console.WriteLine(MethodInfo.GetCurrentMethod().Name);
    a();
}

此代码将返回一个模糊的字符串，如下所示：

b__0。

有没有办法忽略匿名方法并获得更易读的方法名称？

原文

public static void Main(string[] args)
{
    Action a = () => Console.WriteLine(MethodInfo.GetCurrentMethod().Name);
    a();
}

This code will return an obscure string like so: <Main>b__0.

Is there a way of ignoring the anonymous methods and get a more readable method name?

你可以在外面捕捉它：

var name = MethodInfo.GetCurrentMethod().Name + ":subname";
Action a = () => Console.WriteLine(name);

除此之外；不。

You could capture it outside:

var name = MethodInfo.GetCurrentMethod().Name + ":subname";
Action a = () => Console.WriteLine(name);

Other than that; no.

不，没有。这就是为什么它是一个匿名方法。该名称由编译器自动生成，并保证唯一。如果您想获取调用方法名称，您可以将其作为参数传递：

public static void Main()
{
    Action<string> a = name => Console.WriteLine(name);
    a(MethodInfo.GetCurrentMethod().Name);
}

或者如果您确实想要一个有意义的名称，您将需要提供它：

public static void Main()
{
    Action a = MeaningfullyNamedMethod;
    a();
}

static void MeaningfullyNamedMethod()
{
    Console.WriteLine(MethodInfo.GetCurrentMethod().Name);
}

No, there isn't. That's why it is an anonymous method. The name is automatically generated by the compiler and guaranteed to be unique. If you want to get the calling method name you could pass it as argument:

public static void Main()
{
    Action<string> a = name => Console.WriteLine(name);
    a(MethodInfo.GetCurrentMethod().Name);
}

or if you really want a meaningful name you will need to provide it:

public static void Main()
{
    Action a = MeaningfullyNamedMethod;
    a();
}

static void MeaningfullyNamedMethod()
{
    Console.WriteLine(MethodInfo.GetCurrentMethod().Name);
}
