This might help some one.

Here I am using Windows.Forms.Timer and two text boxes for displaying [X and Y] cursor positions. On timer tick calling the API GetCursorPos and getting the cursor position.

public partial class Form1 : Form
{
    [DllImport("user32.dll")]
    static extern bool GetCursorPos(ref Point lpPoint);

    public Form1()
    {
        InitializeComponent();
        timer1.Start();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        var pt = new Point();

        GetCursorPos(ref pt);
        textBox1.Text = pt.X.ToString();
        textBox2.Text = pt.Y.ToString();
    }   
}
