你应该使用System.Windows.Forms.Cursor.Position："A Point that represents the cursor's position in screen coordinates."

如果您不想引用表单，可以使用interop来获取光标位置：

/// <summary>
/// Struct representing a point.
/// </summary>
[StructLayout(LayoutKind.Sequential)]
public struct POINT
{
    public int X;
    public int Y;

    public static implicit operator Point(POINT point)
    {
        return new Point(point.X, point.Y);
    }
}

/// <summary>
/// Retrieves the cursor's position, in screen coordinates.
/// </summary>
/// <see>See MSDN documentation for further information.</see>
[DllImport("user32.dll")]
public static extern bool GetCursorPos(out POINT lpPoint);

public static Point GetCursorPosition()
{
    POINT lpPoint;
    GetCursorPos(out lpPoint);
    //bool success = User32.GetCursorPos(out lpPoint);
    // if (!success)

    return lpPoint;
}

Cursor.Position将获得鼠标的当前屏幕位置（如果您在Control中，MousePosition属性也将获得相同的值） .

要设置鼠标位置，您必须使用 Cursor.Position 并为其指定一个新的Point：
```
Cursor.Position = new Point(x, y);
```
在创建表单之前，您可以在 Main 方法中执行此操作 .

要回答您的具体示例：
```
// your example
Location.X = Cursor.Position.X;
Location.Y = Cursor.Position.Y;

// sample code
Console.WriteLine("x: " + Cursor.Position.X + " y: " + Cursor.Position.Y);
```
不要忘记添加 using System.Windows.Forms; ，并添加对它的引用（右键单击引用>添加引用> .NET选项卡> Systems.Windows.Forms> ok）

```
System.Windows.Forms.Control.MousePosition
```
Gets the position of the mouse cursor in screen coordinates. "The Position property is identical to the Control.MousePosition property."

要获得该位置，请查看OnMouseMove事件 . MouseEventArgs将为您提供x和y位置...
```
protected override void OnMouseMove(MouseEventArgs mouseEv)
```
要设置鼠标位置，请使用Cursor.Position属性 .

internal static class CursorPosition {
  [StructLayout(LayoutKind.Sequential)]
  public struct PointInter {
     public int X;
     public int Y;
     public static explicit operator Point(PointInter point) => new Point(point.X, point.Y);       
  }

  [DllImport("user32.dll")]
  public static extern bool GetCursorPos(out PointInter lpPoint);

  // For your convenience
  public static Point GetCursorPosition() {
     PointInter lpPoint;
     GetCursorPos(out lpPoint);
     return (Point) lpPoint;
  }

}

初始化当前光标 . 用它来获得X和Y的位置

this.Cursor = new Cursor(Cursor.Current.Handle);
int posX = Cursor.Position.X;
int posY = Cursor.Position.Y;
