如何在 C# 中编写我自己的包装器？

How to write my own wrapper in C#?

提问by Skuta

In my other question, I've been trying to find someone who knows where to find free open source OCR library for C#. However, it seems there is only C++ library and obviously, C++ is not C#.

在我的另一个问题中，我一直在寻找知道在哪里可以找到 C# 的免费开源 OCR 库的人。但是，似乎只有 C++ 库，显然，C++ 不是 C#。

One of the responds suggested to write my own wrapper in C#. I have pretty much no idea how to do it, where to learn to do it, or what it actually is - except I believe it's calling C++ methods in dll by changed method calls, .. that's just assumption, indeed.

其中一个回应建议用 C# 编写我自己的包装器。我几乎不知道怎么做，在哪里学习做它，或者它实际上是什么 - 除了我相信它通过更改的方法调用在 dll 中调用 C++ 方法，..这确实只是假设。

Please, help out one more newbie. Thank you

请再帮助一位新手。谢谢

You can get a good start here:

你可以在这里有一个好的开始：

Call Unmanaged Code. Part 1 - Simple DLLImport

调用非托管代码。第 1 部分 - 简单的 DLLImport

If you're wrapping is very simple, you can get away with P/Invoke. If you actually want managed objects, your easiest solution is probably to write the wrapper in C++/CLI (formerly Managed C++), as that provides a full feature set for managed/unmanaged interop.

如果您的包装非常简单，则可以使用P/Invoke。如果您确实需要托管对象，那么最简单的解决方案可能是在 C++/CLI（以前称为托管 C++）中编写包装器，因为它为托管/非托管互操作提供了完整的功能集。

here's how I do it Interop. It shows you how to do the simple cases (BOOL to bool) as well as a bit of a harder case (passing a struct with pointers to managed memory). Good luck.

这就是我如何做到Interop。它向您展示了如何处理简单的情况（BOOL 到 bool）以及一些更困难的情况（传递带有指向托管内存的指针的结构）。祝你好运。
