.NET Framework中的语言互操作性(基本概念)是什么? [英] What is language interoperability (basic concept) in .NET Framework?

问题描述

我正在阅读Wikipedia中的 .NET Framework 文章，在第一段中介绍了该框架的一般概念，它说:

I'm reading .NET Framework article in Wikipedia, in the first paragraph describes the general concept of this framework, and it says:

它包括一个大型库，并提供跨几种编程语言的语言互操作性(每种语言都可以使用用其他语言编写的代码).

当它声明.NET提供语言互操作性时，共享的是什么:代码还是代码功能?

When it declared that .NET provides language interoperability, what is shared: the code or the code functionality?

例如，我有以下简单代码:

For example, I have the following simple code:

class Math
{
   public double Pow( double a, double b)
   {
      return Math.Pow(a,b);
   }
}

我可以访问C#代码或Math对象的实例化吗?

Do I have access to the C# code or the instantiation of the Math object?

推荐答案

编译C#程序时，它会编译为IL(中间语言).然后，该编译程序可以被任何其他.NET语言使用，例如，Visual Basic程序可以引用您的程序，创建Math类的实例并使用它.

When you compile your C# program, it is compiled into IL (Intermediate Language). That compiled program can then be used by any other .NET language, for example a Visual Basic program could reference yours, create an instance of your Math class and use it.

Visual Basic不在乎(或知道)您的Math类是用C#编写的，它看到的只是一个.NET类.这就是语言的互操作性.如果VB.NET只能使用VB.NET编写的类，而C#只能使用C#编写的类，则这些语言将无法互操作.

Visual Basic doesn't care (or know) that your Math class was written in C#, all it sees is a .NET class. That's language interoperability. If VB.NET could only use classes written in VB.NET, and C# could only use classes written C#, those languages wouldn't be interoperable.
