Is there an easy way to read a fixed length file that will be parsed and it’s
data inserted into a DB table?

Currently, the fixed length file contains 61 columns, and I am defining
variables in my code to store those values.  I am also defining the variables
that specifies the size and position of the columns in the file so I can loop
though the columns and rows correctly.  Below is a code snippet to give you
an idea of what I am doing.  I am open to better way of do this.

public override void FileReader()
{
   // read from the file
   StreamReader oFs;
   string sTemp;
   string[] aData;
   Hashtable oRow;
   string sFile;
   bool bAddRec = !CumulativeResults;
   string sFileNumber;
   string sAccountInfo = string.Empty;
   Int32 iCounter = 0;
   
   // define fields, positions, and lengths
   string sNumber;
   Int32 iNumberLen = 10;
   const Int32 coniNumberPos = 0;
   
   string sCustomerNumber;
   Int32 iCustomerNumberLen = 30;
   const Int32 coniCustomerNumberPos = 1;
   
   string sPhone1;
   Int32 iPhone1Len = 10;
   const Int32 coniPhone1Pos = 2;
   
   sFile = WorkingPath;
   
   if (File.Exists(sFile))
   {
           oFs = File.OpenText(sFile);
           
           sTemp = oFs.ReadLine();
           while (sTemp != string.Empty)
       {

        // parse the line
        iStartPos = 0;
        sNumber = sTemp.Substring(iStartPos, iNumberLen).Trim;
        iStartPos += iNumberLen;

        sCustomerNumber = sTemp.Substring(iStartPos, iCustomerNumberLen).Trim;
        iStartPos += iCustomerNumberLen;

        sPhone1 = sTemp.Substring(iStartPos, iPhone1Len).Trim;
        iStartPos += iPhone1Len;

        // completed parsing the line
        oRow = new Hashtable();
        if (!Information.IsNumeric(sNumber)) {
           sNumber = INVALID_ACCOUNT_ID.ToString;
        }
        oRow.Add("FileNumber".ToLower, sNumber);

        // Account
        oRow.Add("Account".ToLower, sCustomerNumber);

        // HomePhone
        sPhone1 = CleanPhoneNumber(sPhone1);
        oRow.Add("HomePhone".ToLower, sPhone1);
                       
        // increment our row counter...
        iCounter += 1;
        base.DataCol.Add(oRow);
       }
               sTemp = oFs.ReadLine();
   }
}
