的typedef [英] typedef

问题描述

我想给C＃中的类型别名，所以我可以说SOMETYPEID指的是

int等，我怎样才能在C＃上做这个？


类似于c ++中的typedef long SOMETYPEID

解决方案

使用指令

例如


A级{

}


使用B = A;

B b;

嗨先生Tickle，


你可以使用* using *指令

使用SOMETYPEID = System.Int32;


因为c＃没有像头文件那样的东西而且这些alises不是

作为元数据嵌入到程序集中你可以只在文件

中使用它你放这个声明。

本身没有typedef。你可以做这样的事情：


使用SOMETYPEID = System.Int64;


上面的主要缺点是它必须包含在你想要使用SOMETYPEID的每个

代码文件中。

I want to give an alias for a type in C# so i can say SOMETYPEID refers to
int etc, how can I do this on C#?

something like typedef long SOMETYPEID in c++

解决方案

the "using directive"
for example

class A{
}

using B = A;
B b;

Hi Mr. Tickle,

you can use *using* directive
using SOMETYPEID = System.Int32;

Because c# doesn''t have anything like header files and this alises are not
embeded as a metadata in the assemblies you can use it only in the file
where you put this declaration.

There is no typedef per se. You could do something like this, though:

using SOMETYPEID = System.Int64;

The primary drawback to the above is that it must be included in every
code file where you would want to use SOMETYPEID.
