如何将C ++ 2d char数组转换为C＃字符串？ [英] How to convert a C++ 2d char array into C# string?

问题描述

我从C ++返回一个char 2d数组。我把它转换成了一个dll并做了所有包装类的东西，所有东西都准备好了。但是我如何通过C＃数组获取返回的2D char数组中的值？我怎样才能访问它们？我需要获取2D char数组中的值并将它们打印在C＃标签中。请帮助

解决方案

您需要这些步骤。



1.从C＃调用C ++获取大小缓冲区（或调用次数）

2.在C＃中准备足够的byte []
3.调用C ++填充缓冲区

4.使用C＃中的stringbuilder转换byte []


创建一个长字符串并用\ n分隔所有数组字符串并将它们拆分为C＃

I am returning a char 2d array from a C++. I converted this into a dll and did all the wrapper class things and everything is prepared.But how can I get the values in the returned 2D char array through C# array? How can I access them? I need to get the values in the 2D char array and print them in C# labels. Please help

解决方案

you need these steps.

1. call from C# to C++ get the size of the buffer (or count of calls)
2. prepare enough byte[] in C#
3. call the C++ to fill the buffer
4. convert the byte[] with stringbuilder in C#

make a "long string" and separate all your array strings with "\n" and split them in C#
