如何在C＃中转换C char [] [] [英] How to convert a C char[][] in C#

问题描述

大家好，

我正在使用C＃编写Winform项目，我必须使用C编写的dll与OpenVMS机器进行通信。



有些方法使用C char **或unsigned char **参数



当我尝试在字符串数组中翻译那些参数时，字节数组或StringBuilder并调用thoses方法我的软件抛出一个AccesViolation。



当我用IntPtr替换thoses参数并使用Marshal.Copy时我遇到了同样的问题（）;



我的软件是用不安全的选项构建的。



这里有一个来源摘录：

Hi every body,
I'm working on Winform project in C# and I have to use a C written dll to communicate with an OpenVMS machine.

Some methods are using a C char** or an unsigned char** parameters

When i try to "translate" those parameters in string array, byte array or a StringBuilder and call thoses methods my software threw an AccesViolation.

I have the same problem when I replace thoses parameters with an IntPtr and use Marshal.Copy();

My software is build with the unsafe option.

Here an extract from the sources :

[DllImport("IPSecureClt.dll", EntryPoint = "IPSec_ListProjet")]
public static extern int IPSec_ListProject(
[In][Out][MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.LPTStr)]
ref string[] cListProjects,int iNbElement, ref int iNbProjects);
);

这里的C声明：

Here the C declaration :

long IPSec_ListProjet(char cList[][256+1], const unsigned long lNbElement, unsigned long *lNbProjets);

如何将Cchar **转换为C＃字符串数组？



感谢您帮助

Take a look on my article and code Calling All Stations. It handles the stuff converting C++ and C# strings and function calling between the runtimes.
