用于创建DLL的编程语言：C ++或C＃ [英] Programming Language for Creating DLL: C++ or C#
问题描述
这不是一个编程怀疑！
我要为某些应用程序编写一个DLL。
我有两个选择：C ++或C＃在哪种语言中我应该写DLL？
I am going to write a DLL for some application. I have two options to choose from: C++ or C# In which language I should write DLL?
这是否会影响功能？
我是一个完全新手，不知道C ++和C＃（但C＃中的一些小程序）。
I am a completely newbie and Unaware of both C++ and C# (but Some Small programs in C#).
什么是优点和缺点在C ++或C＃中编写DLL？
What are Pros and Cons about Writting DLL in C++ or C#?
非常感谢您的时间！

推荐答案
DLL最好用C编写：
A DLL is best written in C :)
让我解释一下：
DLL的概念是在今天没有C ++的时候创建的。它是为C创建的。你可以用C ++编写DLL，但你只能从使用与DLL相同版本的相同编译器编写的应用程序轻松地使用它们。 AC DLL可以从.NET使用，不像C ++（是的，我知道，技术上它可以，但它是一个痛苦的臀部）。
The concept of DLL's was created when ther was no today's C++. It was created for C. You can write DLL's with C++ but you'll be able to easily use them only from applications that were written with the same version of the same compiler as the DLL. A C DLL can be used from .NET, unlike C++ (yeah, I know, technically it can, but it is a pain in the buttocks).
如果你创建DLL与C＃（或任何其他.NET语言），它是一个完全不同的事情 - 它不是一个Windows DLL，它只是一个.Net程序集，没有一个入口点（Main），所以它可以从其他.NET程序集使用，通过引用DLL。
If you create DLL with C#(or any other .NET language), it's a completely other thing - it's not a windows DLL, it's just a .Net assembly without an entry point(Main), so it can be used from other .NET assemblies by referencing the DLL.
总结：
-
如果您需要使用DLL从.NET语言 - 写在C＃，它不会是一个Windows DLL，只是一个程序集。非常容易使用。
If you need to use your DLL from .NET languages - write it in C#, it won't be a windows dll, just an assembly. Very easy to use.
如果你需要使用你的DLL从ONLY C + +和ONLY从相同的编译器应用程序，不便携，易于使用。
If you need to use your DLL from ONLY C++ and ONLY from applications written by the same compiler, write in C++. Not portable, easy to use.
如果您想创建一个可以从.NET，C，C ++使用的通用库，编译器，使用标记为externC的C或C ++独立函数并具有类似指针和POD的C样参数。
If you want to create a general-purpose library that can be used from .NET, C, C++ and regardless of the compiler, use C, or C++ freestanding functions marked as extern "C" and having C-like parameters, like pointers and POD's.
