I have a string with XML in it, like this

string xml="<?xml version=\"1.0\" encoding=\"utf-16\"?>
            <UserInfo xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>  
                <UserName>First_User</UserName>  
                <Age>25</Age>  
            </UserInfo>";

I have to add namespace attribute to UserInfo node like this,without removing the existing ones

<UserInfo xmlns:'abc'>

This is what I am doing

XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.LoadXml(xml);

when I write xmlDoc.SelectNodes("UserInfo"),its not selecting any node How can I add attribute to UserInfo?

are you re-serializing the XML ? – Aniket Inge May 05 '15 at 06:19

Are you able to use LINQ to XML instead of `XmlDocument`? That makes this sort of thing *much* easier. – Jon Skeet May 05 '15 at 06:21

Given that the `UserInfo` element isn't *in* a namespace though, I'd expect it to be fine. Can you post a short but *complete* program demonstrating the problem? – Jon Skeet May 05 '15 at 06:22
@JonSkeet I can use LINQ too, can you suggest some links for that? – Syed Salman Raza Zaidi May 05 '15 at 06:43
I have to add namespace attribute as I have to de-serialize it in a class and class contains a namespace – Syed Salman Raza Zaidi May 05 '15 at 06:44
@JonSkeet check my this question and its accepted answer http://stackoverflow.com/questions/30030943/deserialize-xml-to-class – Syed Salman Raza Zaidi May 05 '15 at 06:45
Your question is really unclear - you're showing code which calls `SelectNodes`, and that *would* select the appropriate node - what's that got to do with adding attributes? (And again, it should be fine...) Is it only the root node that you need to change? – Jon Skeet May 05 '15 at 07:19
