I am reading a bunch of queries from a database. I had an issue with the queries not closing, so I added a CommandTimeout. Now, the individual queries read from the config file each time they are run. How would I make the code cache the int from the config file only once using a static nullable and getter. I was thinking of doing something along the lines of:

static int? var;
get{ var = null;
    if (var.HasValue)
    ...(i dont know how to complete the rest)

My actual code:

private object ExecuteQuery(string dbConnStr, bool fixIt)
{
    object result = false;

    using (SqlConnection connection = new SqlConnection(dbConnStr))
    {
        connection.Open();

        using (SqlCommand sqlCmd = new SqlCommand())
        {
            AddSQLParms(sqlCmd);
            sqlCmd.CommandTimeout = 30;
            sqlCmd.CommandText = _cmdText;
            sqlCmd.Connection = connection;
            sqlCmd.CommandType = System.Data.CommandType.Text;

            sqlCmd.ExecuteNonQuery();
        }
        connection.Close();
    }
    return result;
}}
