wpf坐标转换相关

window = Window.GetWindow(【Visual】);
Point offset = 【Visual】.TransformToAncestor(window).Transform(new Point(0, 0))

上面代码可以获得任意组件的窗口坐标。

获取鼠标相对于任意组件的位置用Mouse.GetPosition(IInputElement relativeTo)或MouseEventArgs.GetPosition(IInputElement relativeTo)

获取屏幕鼠标位置用win32api

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace Samples
{
    class Win32
    {
        [StructLayout(LayoutKind.Sequential)]
        public struct POINT
        {
            public int X;
            public int Y;

            public POINT(int x, int y)
            {
                this.X = x;
                this.Y = y;
            }
        }
        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        public static extern bool GetCursorPos(out POINT pt);     
         
    }
}
