        网络通信共享库NetShare用于保证客户端与服务器通信数据包的规范和统一，客户端与服务器共同使用本库，提升数据包序列化和反序列化的准确性和安全性，并且用于满足不同的通信数据需求。

NetShare：DataPacket（通用数据包）

using System;
using System.IO;
using System.Runtime.Serialization;namespace NetShare

}

NetShare：ServerDataPacket（服务器数据包）

using System.IO;
using System.Runtime.Serialization;namespace NetShare
{/// <summary>/// 服务端数据包/// </summary>[DataContract]public class ServerDataPacket : DataPacket{/// <summary>/// 构造函数/// </summary>public ServerDataPacket(){mLocalEndPointStr = string.Empty;mContent = string.Empty;}/// <summary>/// 将服务端数据包实例转换为字节数组/// </summary>/// <returns>字节数组</returns>public override byte[] ToBytes(){using (MemoryStream ms = new MemoryStream()){DataContractSerializer serializer = new DataContractSerializer(typeof(ServerDataPacket));serializer.WriteObject(ms, this);return ms.ToArray();}}/// <summary>/// 服务端数据包的字符串内容/// </summary>/// <returns>字符串内容</returns>public override string ToString(){return $"[LocalEndPointStr:{mLocalEndPointStr},Content:{mContent}]";}}
}

NetShare：PCDataPacket（私聊频道客户端数据包）

using System.IO;

}

NetShare：PSDataPacket（私聊频道服务器数据包）

using System;
using System.IO;
using System.Runtime.Serialization;namespace NetShare
{/// <summary>/// 私聊频道服务端数据包/// </summary>[DataContract]public class PSDataPacket : ServerDataPacket{/// <summary>/// 已与服务器进行连接的客户端名称合集/// </summary>[DataMember]public string[] mClientNames;/// <summary>/// 构造函数/// </summary>public PSDataPacket(){mClientNames = Array.Empty<string>();}/// <summary>/// 将私聊频道服务端数据包实例转换为字节数组/// </summary>/// <returns>字节数组</returns>public override byte[] ToBytes(){using (MemoryStream ms = new MemoryStream()){DataContractSerializer serializer = new DataContractSerializer(typeof(PSDataPacket));serializer.WriteObject(ms, this);return ms.ToArray();}}}
