Winforms循環不起作用

嗨，我們正在爲我們的學校製作一個應用程序，我們需要每5秒鐘更新（刷新）的表單。我們嘗試了一個簡單的「do while」循環和定時循環，但似乎沒有任何工作，任何人都可以幫忙嗎？Winforms循環不起作用

代碼效率不高，但我們剛剛開始程序員。我們想要循環的部分是從timer1_tick部分到結尾的所有內容。

如果你看看你，如果條件你會看到你多次檢查相同的東西。這不是必需的。您可以將所有子條件放入一個if子句中。 –

您需要啓動定時器：

timer1.Start();

而你需要調用的函數InitializeTimer，最好是在構造函數中

public Form1() 
{ 
    InitializeComponent(); 

    InitializeTimer(); 
}

對不起，我很新的pogramming，你能告訴我我應該把它放在哪裏嗎？ –

@CrazeJocker我編輯了我的答案。構造函數將在表單創建時調用。這樣你的計時器將被初始化 –
