本文将介绍C++中通过DLL来调用C#代码。
首先建立C#的“类库”工程CShapeDLL。
然后输入如下代码:
[csharp] view plain copy
//C++通过DLL调用C#代码

//By MoreWindows( http://blog.csdn.net/MoreWindows )
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace CShapeDLL
{
public class CMyAddClass
{
private int m_nNumber1;
private int m_nNumber2;
public int Number1
{
set { m_nNumber1 = value; }
get { return m_nNumber1; }
}
public int Number2
{
set { m_nNumber2 = value; }
get { return m_nNumber2; }
}
public int AddFunc()
{
return m_nNumber1 + m_nNumber2;
}
}
public class CMyWriteLine
{
private string m_strText;
public string Text
{
set { m_strText = value; }
get { return Text; }
}
public void WriteLineFunc()
{
Console.WriteLine(m_strText);
}
}
}

这里有两个类,一个是MyAddClass类,是用来做加法运算的,另一个是CMyWriteLine,用来输出文本的。
然后以C++控制台程序为例,C++代码如下:
[cpp] view plain copy
//C++通过DLL调用C#代码
//http://blog.csdn.net/morewindows/article/details/8678431
#using "CShapeDLL\\CShapeDLL\\bin\\Debug\\CShapeDLL.dll"
//#using "CShapeDLL\\CShapeDLL\\bin\\Release\\CShapeDLL.dll"
#include
#include
using namespace CShapeDLL;
int main()
{
printf(" C++通过DLL调用C#代码\n");
printf(" - By MoreWindows( http://blog.csdn.net/morewindows/article/details/8678431 ) -\n\n");
CMyWriteLine ^ writeLineClass = gcnew CMyWriteLine;
writeLineClass->Text = "使用C# 的CMyWriteLine示范";
writeLineClass->WriteLineFunc();
writeLineClass->Text = "By MoreWindows (http://blog.csdn.com/MoreWindows)";
writeLineClass->WriteLineFunc();
writeLineClass->Text = "http://blog.csdn.net/morewindows/article/details/8678431";
writeLineClass->WriteLineFunc();
printf("\n ---------------------------------- \n");
CMyAddClass ^ addClass = gcnew CMyAddClass;
addClass->Number1 = 3;
addClass->Number2 = 5;
printf("使用C# 的CMyAddClass示范\n");
printf("%d + %d = %d\n", addClass->Number1, addClass->Number2, addClass->AddFunc());
getch();
return 0;
}

编译,出错。提示如下:
fatal error C1190: 托管目标代码需要“/clr”选项
好吧,修改下,在“属性”->“配置属性”->“常规”->“公共语言运行库支持”中选取“公共语言运行库支持(/clr)”。如下图所示(图片访问不了?请访问http://blog.csdn.net/morewindows/article/details/8678431)。
