在C中调用C＃.NET的静态函数（ICLRRuntimeHost_ExecuteInDefaultAppDomain） [英] Calling static function of C# .NET in C (ICLRRuntimeHost_ExecuteInDefaultAppDomain)

问题描述

我有用C＃.NET Framework 2.0编写的此类 KernelHelper 。我想做的就是在C程序中调用其静态函数。

I have this class KernelHelper which is written in C# .NET Framework 2.0. What I want to do is call its static functions in a C program.

namespace Kernel.Client {

    public class KernelHelper {

        public static int testc(string msg) {
            // Removing the message box does not change anything
            System.Windows.Forms.MessageBox.Show(msg);
            return 0;
        }

        // ...

    }
}

可以编译，到目前为止似乎没有任何问题。但是调用 ICLRRuntimeHost_ExecuteInDefaultAppDomain（）会返回 0x80131513 ，这根据这我没有遵循正确的签名约定的事实。但这不是问题。

which compiles and does not seem to make any problems so far. But calling ICLRRuntimeHost_ExecuteInDefaultAppDomain() returns 0x80131513 which is according to this the fact that I didn't follow the correct signature convention. But this can not be the problem.

#if defined(_WIN32)
#   include <Windows.h>
#   define COBJMACROS
#   define CINTERFACE
#   include <mscoree.h>
#endif 

// ...

HRESULT status;
ICLRRuntimeHost *Host;
BOOL Started;
DWORD Result;

Host = NULL;
Started = FALSE;

status = CorBindToRuntimeEx(
             NULL,
             NULL,
             0,
             &CLSID_CLRRuntimeHost,
             &IID_ICLRRuntimeHost,
             (PVOID *)&Host
             );

if (FAILED(status)) {
    printf("failed 1\n");
}

status = ICLRRuntimeHost_Start(Host);
if (FAILED(status)) {
    printf("failed 2\n");
}

Started = TRUE;

status = ICLRRuntimeHost_ExecuteInDefaultAppDomain(
             Host,
             L"C:\\svn\\Server\\Kernel\\interface\\bin\\Kernel.Client.dll",
             L"Kernel.Client.KernelHelper",
             L"testc",
             L"My message",
             &Result
             ); 

if (FAILED(status)) {
    printf("failed 3\n");
}

有人可以在这里帮助我吗？

Could anybody help me here?

编辑：
我也尝试了不带消息框的操作，并让该函数只返回 0 ，但是它没有

推荐答案

哇，我没想到自己会这么快找到解决方案。如果您遇到相同的问题，请尝试此。

Wow, I did not expect to find the solution so fast and on my own. If you experiance the same problem try this. It seems not to work for everyone.

我要做的就是将平台目标从我的项目属性中的任何CPU 到 x86 。

All I needed to do is to change the Platform Target from Any CPU to x86 inside my project properties.

编辑：如果有人可以向我展示其他解决方案，我仍然很高兴，因为我仍然无法确定这是否不是问题更改此设置。

If anyone can show me another solution I'd still be glad since I can not tell if this might not be a problem anyway changing this setting.
