How would you insert records into a SQL Server 2005 table from a List using C# with VS2010?

How would you modify the following method to insert each record into a SQL Server 2005 table titled tbl_SMR_Bank_Credits_A that is comprised of the fields f1 through f14 that are
of type nvarchar(255)?

For ex:

f1 =   convertedRow[0]
f2 =   convertedRow[1]
...
f14 = convertedRow[13]

protected void UploadToDB(string fileName)
        {
            FileInfo info = new FileInfo(fileName);
            string tableName = info.Name;

            List<string> rows = new List<string>();

            StreamReader reader = new StreamReader(fileName);
            string record = reader.ReadLine();
            while (record != null)
            {
                rows.Add(record);
                record = reader.ReadLine();
            }

            List<string[]> rowObjects = new List<string[]>();

            int maxColsCount = 0;
            foreach (string s in rows)
            {
                string[] convertedRow = s.Split(new char[] { ',' });
                if (convertedRow.Length > maxColsCount)
                    maxColsCount = convertedRow.Length;
                rowObjects.Add(convertedRow);
            }
        }
