haveOrder(出牌權限)傳遞的具體實現：
在服務器選擇地主時，把出牌權限一並傳給地主，所以出牌是由地主開始的。這裡我先假設地主為服務器。
服務器在叫地主後，出了本局第一組牌，下面看一下出牌按鈕的處理程序：
private void btnLead_Click(object sender, EventArgs e) //出牌按鈕的事件處理程序
{
if (player1.lead())//嘗試出牌，該方法的代碼見上文，如果出牌成功，執行以下代碼
{
this.btnLead.Visible = false;
this.btnPass.Visible = false;//隱藏出牌和不要按鈕
if (this.server != null) //當玩家為服務器時
{
server.SendDataForClient("SPokerCount" + Convert.ToString(this.player1.pokers.Count), 1); //發送自己牌的剩余張數給clIEnt1
Thread.Sleep(100);//延遲100毫秒
server.SendDataForClient("SPokerCount" + Convert.ToString(this.player1.pokers.Count), 2);發送自己牌的剩余張數給clIEnt2
Thread.Sleep(100);
server.SendDataForClient("server", DConsole.leadPokers, 1);//發送自己出的牌組給clIEnt1
Thread.Sleep(100);
server.SendDataForClient("server", DConsole.leadPokers, 2);//發送自己出的牌組給clIEnt2
Thread.Sleep(100);
if (this.player1.pokers.Count == 0 && DConsole.IsStart) //當server端牌的張數為0並且游戲已經開始時
{
DConsole.Winer = 1; //勝利者為1,即server,這裡是計分系統,很簡單,不贅述
DConsole.Restart();//重新開始游戲
}
else
{
server.SendDataForClient("Order", 2); //這裡就是傳遞權限的關鍵代碼,當server端出牌並且牌沒有出完時,傳遞出牌權限給server端的下家,根據權限傳遞順序,server-client2-clinet1,所以這裡把出牌權限傳遞給clIEnt2
}
DConsole.player1.haveOrder = false; //自己的出牌權限已經消失
}
if (this.clIEnt != null) //當玩家為客戶端時
{
clIEnt.SendDataForServer("PokerCount" + Convert.ToString(this.player1.pokers.Count)); //發送客戶端牌的剩余張數給服務器,服務器會處理並轉發給另一個客戶端
Thread.Sleep(500);
client.SendDataForServer("client", DConsole.leadPokers);//發送客戶端出牌牌組給服務器,服務接收到該消息後,就知道客戶端1或者客戶端2已出牌,如果該消息是客戶端1發出的,根據權限傳遞順序clIEnt2-clinet1-server，服務器會獲得出牌權限，如果該消息是客戶端2發出的，服務器會發送消息給客戶端1使客戶端1擁有出牌權限
Thread.Sleep(100);
this.player1.haveOrder = false; //自己的出牌權限消失
}
player1.g.Clear(this.BackColor);
player1.Paint();
DConsole.PaintPlayer1LeadPoker();
}
else
{
DConsole.Write("[系統消息]:您出的牌不符合規則!");
}
}
來看看server類中有關出牌權限傳遞的相關處理程序:
/// <summary>
/// 循環接收客戶端1的請求數據
/// </summary>

NetworkStream Ns1 = clIEnt1.GetStream();

//(省略N行)
