I want to put all the database data in the list

Question

 List<int> values = new List<int>();

string sql = "SELECT Values_To_Add FROM table";

command.CommandText = sql;

MySqlDataReader reader = command.ExecuteReader(); 
while(reader.Read())
{
    values.Add(reader["Values_To_Add "]);
}

Error CS1503 Argument 1: cannot convert from 'object' to 'int'

Someone's idea?

Answer 1

You should cast the value from the reader as integer. You can do it safely like this:

 var intValue = reader["Values_To_Add"] as int?;
 if (intValue != null) { values.Add(intValue.Value); }
