TicketSystem

TicketSystem，簡易訂票系統實作。
該服務提供三支API，並且實作簡易訂票系統，並以C# lock鎖避免race condition(競爭條件)，確保大量訂票不會遇到資料重複存取問題。
並且於測試案例中採用了80000人同時非同步購買同一張票的情況，結果為正常訂票，未有多售出之問題。 (https://github.com/yuhsiang237/TicketSystem/blob/master/TicketSystemTest/Services/TicketServiceTest.cs)

關鍵字: Race condition、系統架構分層(邏輯層/資料層)、單元測試

Start

使用Visual Studio 2022 開啟./TicketSystem/TicketSystem.sln，後即可運行
