使用C＃在Visual Studio中的GUI標簽中打印數組

Question

因此，我試圖找出如何在程序中打印出保齡球名稱和得分的列表。 使用控制台時，這很簡單。 我試圖弄清楚如何在GUI上將數組打印到標簽中？ 有什么建議么？ 我嘗試了if / else if語句，但顯然沒有用。

這是我的表單代碼：

Answer 1

作為一般解決方案，我建議使用LINQ輸出每個項目一個String的列表，然后使用String.Join將它們連接成一個String是最簡潔的選擇，例如

myLabel.Text = string.Join(Environment.NewLine, myArray.Select(obj => string.Format("{0}, {1}", obj.Property1, obj.Property2)));
