C#悬浮窗问题

Question

单击悬浮窗FlowMon时会弹出悬浮窗MainForm,如何让MainForm捕捉到FlowMon的位置进而在它的左上方显示呢？就是想把FlowMon的位置坐标传递给MainForm，从而决定MainForm的位置坐标。
FlowMon的初始化代码如下：  private void FlowMon_Load(object sender, EventArgs e)
        {
            this.Show();
            this.Top = 300;
            this.Left = Screen.PrimaryScreen.Bounds.Width - 600;
            this.Opacity = 1.0;
        }MainForm的初始化代码如下： private void MainForm_Load(object sender, EventArgs e)
        {
            this.Show();
            this.Top = 300;
            this.Left =Screen.PrimaryScreen.Bounds.Width - 600;
            this.Opacity = 1.0;
        }

Answer 1

Application.OpenForms["MainForm"].Location

Answer 2

赋值给location  不要赋给对应的x，y

Answer 3

单击事件里面 Form frm = Application.OpenForms["MainForm"];
            if (frm == null)
            {
                MainForm frmMain = MainForm  frmMain();
                //在这设置属性也就像你所谓的坐标吧
            }
            else
            {
                MessageBox.Show("该窗体已存在....");
                return;
            }

Answer 4

Application.OpenForms["MainForm"].Location = Application.OpenForms["FlowMon"].Location;
这样的话MainForm就把FlowMon挡住了……我想获得FlowMon的（x,y)坐标，让MainForm在FlowMon的左上方，该怎么实现呢？

Answer 5

 Application.OpenForms["MainForm"].Location = new Point(Application.OpenForms["FlowMon"].Location.X, Application.OpenForms["FlowMon"].Location.Y+30);
