问题描述

总的来说，我对 VB 和 .NET 非常熟悉，但我只是遇到了这段代码:

I'm quite familiar with VB and .NET in general, but I just ran across this code:

Me.[GetType]()

GetType 括号的用途是什么?

推荐答案

方括号用于告诉编译器他应该将它解释为一个类型，即使它是一个关键字.但是您的示例应该与 Me.GetType() 相同.

The square brackets are used to tell the compiler that he should interpret it as a type, even if it would be a keyword. But your example should be the same as Me.GetType().

例如，您可以将它用于枚举.

You could use it for example for Enums.

示例枚举:

Enum Colors
    Red
    Green
    Blue
    Yellow
End Enum 'Colors

Dim colors = [Enum].GetValues(GetType(Colors))
For Each c In colors
   Console.WriteLine(c)
Next

那不会正常编译:

Enum.GetValues(GetType(Colors)) 'because Enum is a keyword'
