.NET簡陋服務器

雖然是世界上最簡陋的服務器，但是也有幾個注意點：
1.因為要一個死循環監聽客戶端響應，也就是說無法和用戶進行交互了，所以防止前臺假死就要為監聽新起一個線程；
2.要把新起的線程td.IsBackground = true;設置為后臺線程，這樣的話線程才會隨著應用程序的關閉而關閉，不然的話關了窗體，它還在運行；
3.跨線程問題，在新的線程里改變UI會報跨線程改變UI的錯誤，所以要用Invoke;
4.在監聽的死循環中加入 Thread.Sleep(1);這樣可以提高應用程序性能，不要擔心當服務的線程正在Sleep的時候來了個請求服務器會收不到，其實是收得到的。
加入Thread.Sleep(1)的CPU如圖：
不加Thread.Sleep(1)的CPU如圖：
所以一定要加！
所以服務器端代碼如下：
