读写并口报外部组件异常，怎么回事？
程序如下： （Inpout32.dll已经放到system目录下）

public class PortAccess
{

[DllImport( "inpout32.dll ", EntryPoint = "Out32 ")]
public static extern void Output(int adress, int value);

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

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

[解决办法]
