XML file creation using XDocument in C#

LINQ to XML allows this to be much simpler, through three features:

• You can construct an object without knowing the document it's part of
• You can construct an object and provide the children as arguments
• If an argument is iterable, it will be iterated over

So here you can just do:

void Main(){    List<string> list = new List<string>    {        "Data1", "Data2", "Data3"    };    XDocument doc =      new XDocument(        new XElement("file",          new XElement("name", new XAttribute("filename", "sample")),          new XElement("date", new XAttribute("modified", DateTime.Now)),          new XElement("info",            list.Select(x => new XElement("data", new XAttribute("value", x)))          )        )      );    doc.Save("Sample.xml");}

I've used this code layout deliberately to make the code itself reflect the structure of the document.

If you want an element that contains a text node, you can construct that just by passing in the text as another constructor argument:

// Constructs <element>text within element</element>XElement element = new XElement("element", "text within element");

Using the .Save method means that the output will have a BOM, which not all applications will be happy with.If you do not want a BOM, and if you are not sure then I suggest that you don't, then pass the XDocument through a writer:

using (var writer = new XmlTextWriter(".\\your.xml", new UTF8Encoding(false))){    doc.Save(writer);}
