How to run multiple SQL commands in a single SQL connection?

Question

I am creating a project in which I need to run 2-3 SQL commands in a single SQL connection. Here is the code I have written:

SqlConnection con = new SqlConn

No one has mentioned this, but you can also separate your commands using a ; semicolon in the same CommandText:

using (SqlConnection conn = new SqlConnection(connString))
    {
        using (SqlCommand comm = new SqlCommand())
        {
                comm.Connection = conn;
                comm.CommandText = @"update table ... where myparam=@myparam1 ; " +
                                    "update table ... where myparam=@myparam2 ";
                comm.Parameters.AddWithValue("@myparam1", myparam1);
                comm.Parameters.AddWithValue("@myparam2", myparam2);
                conn.Open();
                comm.ExecuteNonQuery();

        }
    }
