Want to Create an Xml format through C# source code.

in which format is your input data?

check at the "Generate a XML output" section from http://emoreau.com/Entries/Articles/2009/04/Using-LINQ-and-XML-Literals-to-transform-a-DataTable-into-a-HTML-table.aspx

I've had to do this sort of thing with JSON.  From the question I'm spit balling here but I would created a class hierarchy to manage building the the message. The structure of XML lends itself to that nicely.  Each class<like message> would now the tags it would use to wrap itself as well as each field. An taking it in chunks helped me to work out the user interface.

<Message> cMessage
   <Request> cRequest
      <Detail> cDetail
         <TranType>Credit</TranType> member
         <TranAction>Auth</TranAction>member
         <Amount>19.99</Amount>
         <CurrencyCode>840</CurrencyCode>
      </Detail>
      <IndustryData> cIndustryData
         <Industry>CardNotPresent</Industry>
         <Eci>7</Eci>
      </IndustryData>
      <Account>
         <Pan>4111111111111111</Pan>
         <Expiration>1217</Expiration>
         <Postal>197201234</Postal>
         <Address>123 Fake Street</Address>
      </Account>
   </Request>
   <Authentication>
      <Client>73</Client>
      <Source>1</Source>
   </Authentication>
</Message>

The approach is fairly strait forward

Please share with us the source of the input data and its format which will be used to create the XML document.

Hi  TAPAN;

The XML that you posted has no node with the name Response and also has no root node. Which part do you want to get?

How will I add Root node as "<Response>"  in the above xml string which I am receiving from the client and I want to save the above xml file. File should be like this.

<Response>
 <Reference>......</Reference>
 <Result>......</Result>
<QueryResponse>.........</QueryResponse>
</Response>

Thank you so much
