char *转换为C#中的字符串 [英] char* to a string in C#

问题描述

我正在从本机DLL调用一个返回char*指针的函数，如何将返回的指针转换为字符串? 我试过了:

I'm calling a function from a native DLL which returns a char* pointer, how can I convert the returned pointer to a string ? I tried :

char* c = function();
string s = new string(c);

但是它只是返回了一个奇怪的汉字，这不是c的正确值.

But it just returned a weird Chinese character, which isn't the right value for c.

推荐答案

也许本机DLL实际上返回的是ANSI字符串而不是Unicode字符串.在这种情况下，请致电Marshal.PtrToStringAnsi:

Perhaps the native DLL is actually returning an ANSI string instead of a Unicode string. In that case, call Marshal.PtrToStringAnsi:

using System.Runtime.InteropServices;
...
string s = Marshal.PtrToStringAnsi((IntPtr)c);
