为什么我获取不到 GetType() 的 MethodBody？
Why can't I get the MethodBody of GetType()?
假设我有这条线：
MethodBody getTypeMethod = typeof(object).GetMethod("GetType").GetMethodBody();
// getTypeMethod is null
为什么 getTypeMethod 为空？如何获取GetType()方法的MethodBody？
您自己找到了答案，但只是为了确认，Object.GetType() 是一个外部方法，外部方法没有指定方法体。
来自 C# 规范 10.6.7
When a method declaration includes an extern modifier, that method is
said to be an external method. External methods are implemented
externally, typically using a language other than C#. Because an
external method declaration provides no actual implementation, the
method-body of an external method simply consists of a semicolon.
