@Osama Abdelkader , If you want to get the count of the rows in the table, there is no need to use the SqlDatareader.
Here is a code example you could refer to.
string connstr = "connstr"; SqlConnection connection = new SqlConnection(connstr); connection.Open(); string comamnd = "select COUNT(*) from Student"; SqlCommand com = new SqlCommand(comamnd, connection); int Cond = Convert.ToInt32(com.ExecuteScalar().ToString()); Console.WriteLine(Cond); connection.Close();
Hope the code example could help you. If I have some misunderstanding, Pleas feel free to let me know.
