自己動手設計多人聊天室程式 - 使用 C#
程式下載：ChattingRoom.zip
// ---------------------------------------------------------------
// 共有5個程式檔案
//
// 程式檔 : ChatLib.cs
// 程式檔 : ChattingServer.cs
// 程式檔 : FormChatClient.cs
// 程式檔 : FormChatClient.Designer.cs
// 程式檔 : WinChatClient.cs
//
// 編譯方式 :
// 步驟 1 : csc ChattingServer.cs ChatLib.cs
// 會產生 ChattingServer.exe 檔
//
// 步驟 2 : csc FormChatClient.cs FormChatClilent.Designer.cs ChatLib.cs
// 會產生 FormChatClient.exe 檔
//
// 執行方式 :
// 步驟 1 : 執行 ChattingServer.exe
// 步驟 2 : 執行 FormChatClient.exe
// 步驟 3 : 執行 FormChatClient.exe
//
// 如此，兩個 FormChatClient.exe 的視窗間即可透過本機聊天
