标签上包含C#键 [英] C# bonds contains on a label

问题描述

这是mt代码
beatdetector = picurebox

this is mt code
beatdetector= picurebox

foreach (Control pControl in panel1.Controls)
            {
              Label pLabel=pControl as Label;
              if (null != pLabel)
              {
if (BeatDetector.Bounds.Contains(pLabel))
                     {
                         msgbox.show("it touched!!!");
                     }

              }

             }

这是我的2个错误
Error 1 The best overloaded method match for ''System.Drawing.Rectangle.Contains(System.Drawing.Rectangle)'' has some invalid arguments Z:\ll Studio\ll Studio\Form1.cs 193 29 ll Studio

Error 2 Argument 1: cannot convert from ''System.Windows.Forms.Label'' to ''System.Drawing.Rectangle'' Z:\ll Studio\ll Studio\Form1.cs 193 58 ll Studio

我知道它不是矩形或其他任何形状，但是我想知道这是否可能吗?

I know its not a rectangle or whatever, but I was wondering if this is possible?

推荐答案

尝试:

if (BeatDetector.Bounds.Contains(new Rectangle(pLabel.Location, pLabel.Size)))

但是，您可能要改为检查四个角点中的每一个-Rectangle.Contains只会找到 整个 的对象在矩形内.如果您使用标签的边界矩形进行检查，则它将仅检测标签何时完全在BeatDetector内.您可以使用Rectangle.Contains(Point)或Rectangle.Contains(int，int)

However, you may want to check each of the four corner Points instead - Rectangle.Contains will only find objects which are entirely within the rectangle. If you check using the bounding rectangle for the label, then it will only detect when the label is entirely within the BeatDetector. You can use Rectangle.Contains(Point) or Rectangle.Contains(int, int)
