I use the following code to count the number of rows in a table in MSSQL 2005 DB.
But, how should I write the C# code to get the number?

SQL

SqlConnection objcon = new SqlConnection();
            objcon.ConnectionString = "Data source=localhost; Initial catalog=BRIDGES_DB; User ID=sa; password=123;";
            SqlCommand objcom = new SqlCommand();
            objcom.CommandType = CommandType.Text;
            objcom.CommandText = "SELECT COUNT(marks_org) FROM activity_result";
            objcom.Connection = objcon;
            objcon.Open();
            if (dr.Read())
            {

               Label1.Text=?

            }
            objcon.Close();

You would find the value by doing the following:

C#

Label1.Text = dr[0].ToString();

However, I don't see dr defined anywhere. Make sure you are doing the following:

C#

SqlDataReader dr = objcom.ExecuteReader();

before you do the if statement.

Here is a working tutorial that will point you in the right direction:
