I have a C# class (a lot of lines). 我有一个C#类（很多行）。 I want to use this class in my VB.NET project. 我想用这个class在我VB.NET项目。 So, I tried to add the .cs file to my VB.NET project and then call it by: 因此，我尝试将.cs文件添加到我的VB.NET项目中，然后通过以下方式调用它：

MyclassName.VoidName()

It's not working. 没用

( 'MycalssName' is not declared. It may be inaccessible due to its protection level. ) （ 'MycalssName' is not declared. It may be inaccessible due to its protection level. ）

How can I use a C# class in my VB.NET project? 如何在VB.NET项目中使用C# class ？

您可以简单地将C#代码编译为程序集（DLL），然后从您的VB.NET项目中引用该程序集。

A single .NET assembly/project should contain code written in one supported language only. 单个.NET程序集/项目应仅包含以一种受支持的语言编写的代码。 Compilation of any .NET project will need the language specific MSBuild targets (which are included as part of the project files). 任何.NET项目的编译都需要特定于语言的MSBuild目标（作为项目文件的一部分包含在内）。 So, you will be unable to compile/use a C# language source file in a VB.net project and vice versa. 因此，您将无法在VB.net项目中编译/使用C＃语言源文件，反之亦然。

Ignoring the MSBUild aspects, the compilation of a vb.net project (with ac# source file) will not even suceed, as the syntax will be different and compiler (vbc.exe) will throw a lot of compiler errors. 忽略MSBUild方面，甚至不会成功编译vb.net项目（带有ac＃源文件），因为语法会有所不同，并且编译器（vbc.exe）会引发很多编译器错误。

So, its best to compile the C# project and refer to the types from the VB.net project. 因此，最好编译C＃项目并引用VB.net项目中的类型。
