How do I delete a row with specified index in datagridview

How do I delete a row with a specified index in datagridview? So if I want to delete the row with index [2], then how can I do that?

I have tried:

for (int i = 0; i < dg1.Rows.Count; i++)
{
    if (i == 2)//if iteration has reached index 2
    {
        dg1.Row[i].Delete;
    }
}

I am using Winforms
