.net c# winform获取当前任务栏的位置,宽度和高度

winform 通过调用系统底层方法,获取任务栏位置信息,来计算自己窗体的显示处理.

1.注册底层方法

        [DllImport("user32.dll")]
        public static extern int FindWindow(string lpClassName, string lpWindowName);

        [DllImport("user32.dll")]
        public static extern int GetWindowRect(int hwnd, ref Rectangle lpRect);

2.获取位置信息

            if (GetWindowRect(FindWindow("Shell_TrayWnd", null), ref myrect) == 0) return;
            zleft.Text = Convert.ToString(myrect.Left);
            ztop.Text = Convert.ToString(myrect.Top);
            zright.Text = Convert.ToString(myrect.Right);
            zbottom.Text = Convert.ToString(myrect.Bottom);
            zwidth.Text = Convert.ToString(myrect.Width);
            zheight.Text = Convert.ToString(myrect.Height - myrect.Top);
