Question

我在点击按钮时尝试在运行时添加标签，这是我的代码，但当你点击按钮时，只需在新位置添加新标签，然后点击该按钮即可显示之前制作的标签我想在点击按钮后逐一显示所有这些内容我该如何解决？

Label lbl;
int number;
int locationX = 2;
int locationY = 4;

public void CreateRuntimeControl(PictureBox pic)
{
    lbl; = new Label();
    number++;
    locationX++;
    locationY++;
    lbl.Name = "lbl" + number.ToString();
    lbl.Size = new System.Drawing.Size(100, 50);
    lbl.Location = new System.Drawing.Point(10 + locationX, 10 + locationY);
    lbl.Text = number.ToString();
    lbl.BackColor = Color.Gray;
    pic.Controls.Add(lbl);
}

Answer 1

你应该移动lbl = new Label（）;声明到CreateRuntimeControl（）函数的主体，否则你重新使用相同的标签，只是移动它而不是创建新标签

Answer 2

尝试：

int number;
int locationX = 2;
int locationY = 4;

public void CreateRuntimeControl(PictureBox pic)
{
    Label lbl = new Label();
    number++;
    locationX++;
    locationY++;
    lbl.Name = "lbl" + number.ToString();
    lbl.Size = new System.Drawing.Size(100, 50);
    lbl.Location = new System.Drawing.Point(10 + locationX, 10 + locationY);
    lbl.Text = number.ToString();
    lbl.BackColor = Color.Gray;
    pic.Controls.Add(lbl);
}
