以上定义的都是数值不变的常量
---------------------------------------------------
private delegate void HandleInterfaceUpdateDelegate(byte[] RecvData,int iLen); //委托，此为重点
创建一个参数为byte[]的无返回值的委托。
----------------------------------------------------------
private HandleInterfaceUpdateDelegate interfaceUpdateHandle;
private byte[] PackageBuf = new byte[4096];
private int PackageBufLength = 0;
FDataShow pFDataShow;
FDataShow1 pFDataShow1;
定义一些变量
-----------------------------------------------------------
interfaceUpdateHandle = new HandleInterfaceUpda
