本文主要介紹了C#實現(xiàn)網(wǎng)絡(luò)通信共享庫NetShare，網(wǎng)絡(luò)通信共享庫NetShare用于保證客戶端與服務(wù)器通信數(shù)據(jù)包的規(guī)范和統(tǒng)一，感興趣的可以了解一下

前言
NetShare：DataPacket（通用數(shù)據(jù)包）
NetShare：ClientDataPacket（客戶端數(shù)據(jù)包）
NetShare：ServerDataPacket（服務(wù)器數(shù)據(jù)包）
NetShare：PCDataPacket（私聊頻道客戶端數(shù)據(jù)包）
NetShare：PSDataPacket（私聊頻道服務(wù)器數(shù)據(jù)包）

前言

網(wǎng)絡(luò)通信共享庫NetShare用于保證客戶端與服務(wù)器通信數(shù)據(jù)包的規(guī)范和統(tǒng)一，客戶端與服務(wù)器共同使用本庫，提升數(shù)據(jù)包序列化和反序列化的準確性和安全性，并且用于滿足不同的通信數(shù)據(jù)需求。
