Question

I ve created a C# application. Within this application I would like to use/run a C++ API from another project(the API is written in macro coding). I tried import the dll of that C++ project and tried to call a functions which belongs to that API. The problem is that it throws "unable to find method" error.

我如何在C#项目中开展C++项目?

Answer 1

你可以增加一个本地的DLL,作为管理项目的一个参考。你有三个主要选择:

Make the native functions available with p/invoke.
Expose the native code through COM.
Compile the native code as a managed C++ assembly.

对于任何严重的法典,选项3是最有成效和最有效的方法。

Answer 2

If by "running", you mean a separate process:

Use the class System.Diagnostics.Process available in .NET:

myProcess.StartInfo.FileName = "notepad.exe";
myProcess.StartInfo.CreateNoWindow = false;
myProcess.Start();

如果你指使用C++中开发的批号,你可使用<代码>。平台:

using System;
using System.Runtime.InteropServices;

class PlatformInvokeTest
{
    //First param is of course either in your PATH, or an absolute path:
    [DllImport("msvcrt.dll", EntryPoint="puts", CallingConvention=CallingConvention.Cdecl)]
    public static extern int PutString(string c);
    [DllImport("msvcrt.dll", CallingConvention=CallingConvention.Cdecl)]
    internal static extern int _flushall();

    public static void Main() 
    {
        PutString("Test");
        _flushall();
    }
}
