vb.net 怎样获取鼠标单击点的坐标

当鼠标在本窗口单击时，获得单击点在本窗口的坐标

Answer 1

通过窗体的MouseDown事件的e.X和e.Y属性获取。通过e.Location属性获取Point类型的坐标。

下面的代码示例使用 Location 属性跟踪鼠标左键单击，并绘制一系列直线段作为对用户输入的响应。如果隐藏窗体然后重新显示它，此示例不保留已绘制的线段，该代码为简单起见而被省略了。
Dim FirstPoint As Point
Dim HaveFirstPoint As Boolean = False

Sub Form1_MouseDownDrawing(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
If HaveFirstPoint Then
Dim g As Graphics = Me.CreateGraphics()
g.DrawLine(Pens.Black, FirstPoint, e.Location)
HaveFirstPoint = False
Else
FirstPoint = e.Location
HaveFirstPoint = True
End If
End Sub
