没有主体的C#方法 [英] C# methods with no body

问题描述

我是C#的新手，在我将要研究的代码库中遇到了类似的事情(这些特定示例来自Microsoft.Extensions.CommandLineUtils).

I'm new to C# and have come across stuff like this in the codebase I'll be working on (these specific examples are from Microsoft.Extensions.CommandLineUtils).

public CommandArgument Argument(string name, string description, Action<CommandArgument> configuration, bool multipleValues = false);
public CommandArgument Argument(string name, string description, bool multipleValues = false);

我真的只想知道调用此函数的含义以及调用这些函数时的实际情况?我猜他们是具有一些编译时魔术的代理，但不确定.

I really just want to know what this construct is called and what's actually going on when you call these functions? I'm guessing they are proxies with some compile time magic but not sure.

推荐答案

这不是有效的C#代码.

It is not a valid C# code.

很有可能您在VS.Net中单击了转到定义"/F12，并且向您显示了外部DLL的元数据.

Most probably you clicked "Go to Definition" / F12 in VS.Net, and you were presented with metadata of external DLL.
