首先建立C#的“类库”工程CShapeDLL。
然后输入如下代码：
[csharp]

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);
}
}
}

// By MoreWindows( http://blog.csdn.net/MoreWindows )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]
//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 CMyA
