小编给大家分享一下C#中如何调用Cards.dll实现图形化发牌功能，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
具体如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using System.Windows.Forms.Design;

public static extern bool cdtInit(ref int width, ref int height);
[DllImport("cards.dll")]
public static extern void cdtTerm();
[DllImport("cards.dll")]
public static extern bool cdtDraw(IntPtr hdc,int x,int y,int card,int mode,long color);
//mode=0表正面,1表反面,Color我从0-0xFF000试了很多,好象没颜色改变
//[DllImport("cards.dll")]
//public static extern bool cdtDrawExt(IntPtr hdc,int x,int y,int dx,int dy,int card,int type,long color);
//[DllImport("cards.dll")]
//public static extern bool cdtAnimate(IntPtr hdc,int cardback,int x,int y,int frame);

{

}
}

for (int i = 0; i < 52; i++)
{

}
for (int i = 0; i < 52; i++) //就是做52次随机交换两张牌
{

}

{

}
}界面设计的话截图比贴Designer.cs省事多了:
