Where's the data coming from that needs to go into the XML - kaj 2012-04-04 07:14

You can use XmlSerializer and create a simple class with properties according to the template:

public class User
{
   public UserId{get;set;}

   ...
}

And serialize the class to XML file.

There's a good example here.

Option #2:
If for some reason you do not want to use XmlSerializer use XmlWriter - in order to prevent forgetting to close elements I suggest you use "AutoClose" XmlWriter - I've blogged about how to create this simple class on my blog - XmlWriter that automatically close elements using IDisposable

i am not plannig to use xmlserialize - user922834 2012-04-04 07:19

Why not? this way you only need to maintain code and do not need to write every single XML node "by hand - Dror Helper 2012-04-04 07:21

i have list in which it contain three objects.I want to create an xml with all three object details,then how it will be - user922834 2012-04-04 07:30

There are several attributes you can use to change the way that take a look at this SO question http://stackoverflow.com/questions/2292480/xmlserializer-list-item-element-nam - Dror Helper 2012-04-04 07:34

XmlWriter that automatically close elements using IDisposable has a pretty good implementation with c# using and .Net IDisposable. If you'd like XmlWriter, this is a good way to avoid all the WriteEnd... methods - gmaran23 2014-05-28 07:06

@gmaran23 You know it's my blog post - right? : - Dror Helper 2014-05-29 08:52

I do:) And I liked the way you of using the using. Seems pretty native c# - gmaran23 2014-06-02 09:32

Serializing is an option, but if you really need a template, you can use this https://github.com/beto-rodriguez/Templator

here is an example

UserClass user = new UserClass();
user.UserId = 1;
user.UserName = "my name";
User.Roles = new List<string>(){"admin", "sales"};
//some other properties...    

var compiler = new Compiler()
            .AddElementToScope("user", user);

var compiled = compiler.CompileXml(@"C:\...\myXml.xml")

XLM Source

<User>
  <UserId>{{user.UserId}}</UserId>
  <UserName>{{user.UserName}}</UserName>
  <Roles Tor.Repeat="role in user.Roles">
    <Role>{{role}}</Role>
  <Roles></Role>
  </Roles>
</User>

Compiled

<User>
  <UserId>1</UserId>
  <UserName>my name</UserName>
  <Roles>
    <Role>admin</Role>
    <Role>sales</Role>
  <Roles></Role>
  </Roles>
</User>

you can install it from Nuget too:

Install-Package SuperXML

var templateXML = "C://template.xml"//full path for the template xml XmlDocument doc = new XmlDocument(); FileStream fs = new FileStream(templateXML, FileMode.Open, FileAccess.Read); doc.Load(fs); XmlNode node = doc.DocumentElement; XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable); nsmgr.AddNamespace("pf", "http://www.example.com/abc"); node = doc.DocumentElement; nodeName = "/pf:Message/pf:User/pf:UserID"; node.SelectSingleNode(nodeName, nsmgr).InnerXml = "user1";put you custom value nodeName = "/pf:Message/pf:User/pf:UserName"; node.SelectSingleNode(nodeName, nsmgr).InnerXml = "fr";put you custom value .... ..... ....... var postData = node.ParentNode.InnerXml; postData = node.OuterXml;
