I have stored procedures, which like
SELECT * FROM settings ORDER BY [name]

Open in new window

or
SELECT [Value] FROM settings WHERE [Name]=@name

Open in new window

I wrote the code for the generic cases below but unfinished.
Thanks for advice.
public string ExecuteReader(string storedProcedure)
        {
            return ExecuteReader(storedProcedure, null);
        }

        public string ExecuteReader(string storedProcedure, Dictionary<string, object> parameters)
        {
            string temp = string.Empty;
            using (SqlConnection conn = new SqlConnection(_connectionString))
            {
                conn.Open();
                using (SqlCommand cmd = new SqlCommand(storedProcedure, conn))
                {
                    cmd.CommandType = CommandType.StoredProcedure;
                    if (parameters != null)
                    {
                        foreach (string parameter in parameters.Keys)
                        {
                            cmd.Parameters.AddWithValue(parameter, parameters[parameter] ?? DBNull.Value);
                        }
                    }
                    using (SqlDataReader reader = cmd.ExecuteReader())
                    {
                        reader.Read();
                        temp=reader.GetValue[
                    }
                   
                }
                conn.Close();
            }
            return temp;
        }

Are you looking for something like this?

 temp1=reader.GetValue["column1"].ToString();

 temp2=reader.GetValue["column2"].ToString();

Yes. Do we need pass the column name?
And also if I used
select * from table

Open in new window

.
Then the program will return a list instead of a string.
We have to override the code?

no it will get all the records anyways so you have to process them one by one.

It's something special you need to do? Why are you putting the values of all the results into a string and not manipulating the data?
