RakNet
RakNet是一個基於UDP網絡傳輸協議的C++網絡庫，允許程序員在他們自己的程序中實現高效的網絡傳輸服務。通常情況下用於遊戲.
個人編程環境 vs2017 /net4.5.1/C#
dll 引用
用到兩個文件:RakNetDotNet.dll 和 RakNet.dll
RakNet庫 https://github.com/OculusVR/RakNet
c#包裝：https://github.com/RainsSoft/RakNet-C-Sharp-binding-project
c#包裝項目名稱: RakNet-C-Sharp-binding-project-master
0.RakNet.dll 有兩個 x86 和x64 版本 編譯調試時要區分
1.RakNetDotNet.dll 和 RakNet.dll 放到項目文件夾裏
2,Solution Explorer => 右鍵 References => add References => Browse => RakNetDotNet.dll => ok button
// 3.RakNet.dll 拖到 Solution Explorer 窗口的=>項目名字上
4.調試或者編譯運行時,先複製 RakNet.dll和RakNetDotNet.dll 文件 到 exe文件夾內
自己的封裝
通過我的自己的封裝一下.
Send方法中沒有ip地址參數的,都是發給默認連接中的第一個
connect 後,通過建立一個線程 後臺執行 Rev ,不停解包 Packet
用包(Packet)的第一個字節(byte)表明包的類型(DefaultMessageIDTypes),而1個字節(byte)最多表示256種不同的狀態
byte byte_ = Packet.data[0];
DefaultMessageIDTypes type = (DefaultMessageIDTypes)byte_;寫入的時候
BitStream bitStream = new BitStream(); bitStream.Write((byte)DefaultMessageIDTypes); bitStream.Write(message); Send(bitStream, PacketPriority.HIGH_PRIORITY, PacketReliability.RELIABLE_ORDERED, (char)0, SystemAddress地址, true);讀取
BitStream receiveBitStream; receiveBitStream.Reset(); receiveBitStream.Write(date.p.data, date.p.length); receiveBitStream.IgnoreBytes(1); receiveBitStream.Read(out date.message);

1. host是一個IP地址，或域名
2. remotePort是遠端系統監聽的端口，傳遞給Startup()函數的端口參數。
3. passwordData是隨着連接請求發送的二進制數據。如果這個參數與傳遞給RakPeerInterface::SetPassword()的參數不同，遠端系統會回覆ID_INVALID_PASSWORD。
4. passwordDataLength是passwordData的長度，單位是字節。
5. publicKey 是遠端系統上傳遞給InitializeSecurity()函數的公用密鑰參數。如果你不適用，傳遞0。
6. connectionSocketINdex是你要發送的客戶端的Socket在傳遞給RakPeer::Startup（）函數的socket描述符的數組中的索引。
7. sendConnectionAttemptCount是在確定無法連接前要做出的發送嘗試次數。這個也用於MTU檢測，使用3個不同的MTU大小。默認的值12意味着發送每個MTU四次，這對於容忍任何原因的包丟失也是足夠的了。更低的值意味着ID_CONNECTION_ATTEMPT_FAILED會更快返回。
8. timeBetweenSendConnectionAttemptsMS是進行另外一次連接嘗試要等待的毫秒數。比較好的值是4倍的ping值。
9. 如果消息不能發送，在丟掉遠端系統之前，爲這次連接，timeoutTime指出了要等待多少毫秒。默認值是0，意味着使用SetTimeoutTime()方法中的全局值。
連接嘗試成功Connect()會返回CONNECTION_ATTEMPT_STARTED值，如果失敗會返回其他的值。
注意：Connect()返回TRUE並不意味着已經連接成功。如果連接成功，應該會返回ID_CONNECTION_REQUEST_ACCEPTED。否則，會收到一條錯誤消息。
