當(dāng)我試圖顯示下劃線時，我試圖制作的劊子手游戲在 for 循環(huán)中拋出“ArgumentOutOfRangeException”。我嘗試重寫代碼，但沒有任何效果。 List<Label> underline; int left = 300; int top = 275; for (int i = 0; i < data.solution.Length; i++) //data is the object that contains the word that is the solution { underline = new List<Label>(); underline[i].Parent = this; underline[i].Text = "_"; underline[i].Size = new Size(35, 35); underline[i].Location = new Point(left, top); left += 30; underline[i].Font = new Font(new FontFamily("Microsoft Sans Serif"), 20, FontStyle.Bold); }我不明白這有什么問題。當(dāng)我點擊新游戲時它會立即拋出它。

首先不要為 for 循環(huán)中的每次迭代創(chuàng)建一個新列表，而是在循環(huán)之外創(chuàng)建它。其次，您必須Label在列表中添加一個新實例，然后才能通過它的索引訪問它：
List<Label> underline = new List<Label>();
int left = 300;
int top = 275;
for (int i = 0; i < data.solution.Length; i++) //data is the object that contains the word that is the solution
{
underline.Add(new Label());
underline[i].Parent = this;
underline[i].Text = "_";
underline[i].Size = new Size(35, 35);
underline[i].Location = new Point(left, top);
left += 30;
underline[i].Font = new Font(new FontFamily("Microsoft Sans Serif"), 20, FontStyle.Bold);
}
