Getting mouse position in c#

Solution 1:

You should use System.Windows.Forms.Cursor.Position: "A Point that represents the cursor's position in screen coordinates."

Solution 2:

If you don't want to reference Forms you can use interop to get the cursor position:

using System.Runtime.InteropServices;
using System.Windows; // Or use whatever point class you like for the implicit cast operator

/// <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);
    // NOTE: If you need error handling
    // bool success = GetCursorPos(out lpPoint);
    // if (!success)
        
    return lpPoint;
}

Solution 3:

Cursor.Position will get the current screen poisition of the mouse (if you are in a Control, the MousePosition property will also get the same value).

To set the mouse position, you will have to use Cursor.Position and give it a new Point:

Cursor.Position = new Point(x, y);

You can do this in your Main method before creating your form.

Solution 4:

To answer your specific example:

// your example
Location.X = Cursor.Position.X;
Location.Y = Cursor.Position.Y;

// sample code
Console.WriteLine("x: " + Cursor.Position.X + " y: " + Cursor.Position.Y);

Don't forget to add using System.Windows.Forms;, and adding the reference to it (right click on references > add reference > .NET tab > Systems.Windows.Forms > ok)
