            FileStream fs = new FileStream(path, FileMode.CreateNew);
            StreamWriter CsvfileWriter = new StreamWriter(fs);
            //This Block of code for getting the Table Headers

            for (int i = 0; i < dr.FieldCount; i++)
            {
                tableColumns.Columns.Add(dr.GetName(i));
            }
            CsvfileWriter.WriteLine(tableColumns.Columns.ConcatUsing(","));

            StringBuilder sb = new StringBuilder();
            while (dr.Read())
            {
                for (int i = 0; i < dr.FieldCount; i++)
                {
                    sb.AppendFormat("{0},", dr[i]);
                }
                sb.AppendLine();
            }
            CsvfileWriter.WriteLine(sb.ToString());

Save the path name is table.

Answer 2

Use LinqToCSV and write the file to the server. Writing should be straight forward using the built in methods of LinqToCSV. Then store the file name in the table.

Answer 3

declare @sql varchar(8000)
select @sql = 'bcp "select * from mytablename where area_code=21" queryout c:\bcp\[filename] -c -t, -T -S' + @@servername
exec master..xp_cmdshell @sql

execute this query you have to set path for write file. currently in this query you have to create a "bcp" folder in "C:\\ "Drive .
