You can use this snippet i stole from a here. Wich was stolen from here.

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

    public class Form1 : Form
    {
       [DllImport("user32.dll",CharSet=CharSet.Auto, CallingConvention=CallingConvention.StdCall)]
       public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);
       //Mouse actions
       private const int MOUSEEVENTF_LEFTDOWN = 0x02;
       private const int MOUSEEVENTF_LEFTUP = 0x04;
       private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
       private const int MOUSEEVENTF_RIGHTUP = 0x10;

       public Form1()
       {
       }

       public void DoMouseClick()
       {
          //Call the imported function with the cursor's current position
          uint X = (uint)Cursor.Position.X;
          uint Y = (uint)Cursor.Position.Y;
          mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
       }

       //...other code needed for the application
    }
