using System.Runtime.InteropServices;

public static extern void Output(int adress, int value);

[DllImport("inpout32.dll", EntryPoint="Inp32")]
public static extern int Input(int adress);
}

//Output函数为给端口传送数据，Input是从端口读取数据如：

PortAccess.Input( 888 );//从888（即0x378）端口读取数据

PortAccess.Output( 888, 4 )//把4从888端口输出
