Reducing linq and convert C#2005

I want to reducing linq code below and convert C# 2005

private void cmdCaculator_Click(object sender, EventArgs e)
{            
     int rowcount = gridView1.RowCount;

     Thread myThr = new Thread(() =>
     {
          for (int i = 0; i < rowcount; i++)
          {
               x *=i;
          }
     });
     myThr.Start();    
}

There's no LINQ in that code - just a lambda expression. You can use an anonymous method instead:

private void cmdCaculator_Click(object sender, EventArgs e)
{            
     int rowcount = gridView1.RowCount;

     Thread myThr = new Thread(delegate ()
     {
          for (int i = 0; i < rowcount; i++)
          {
               x *= i;
          }
     });
     myThr.Start();    
}

However, I would strongly recommend that you update your toolchain. By restricting yourself to C# 2 you're missing out on lots of massively useful features.
