Hai,
I am inserting bulk data(serial number,pin number) to DB.Before inserting,the data from datatable is binded into XML tag.Here the pin number is encrypted one...as follows,
strXml = " version=" + @"""1.0"" encoding=" + @"""iso-8859-1""?><batch>";
strPinXml =strPinXml + "";
strXml = strXml + strPinXml + "";

Problem is after inserting into db, to verify whether the actual pinnumber(encrypted format in db) is inserted, i decrypted the pinnumber and found that,

->The first digit in all data are displaced by (’)single quote and last digit for some pinnumber is empty (if the pinnumber is-œA_¡/Ì·ÞvËÛ (ie)ending in Û for that pins last digit is empty).

Please provide the solution to resolve this issue

Result as follows-
