I use this code -

C#

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.IndentChars = (" " );
settings.CloseOutput = true;
settings.OmitXmlDeclaration = true;
using (XmlWriter writer = XmlWriter.Create("books.xml" , settings))
    {
    writer.WriteStartElement( "book" );
    writer.WriteElementString( "title" , book.Title);
    writer.WriteElementString( "author" , book.Author.Name);
    writer.WriteElementString( "publisher" , book.Publisher);
    writer.WriteElementString( "price" , book.Price.ToString());
    writer.WriteEndElement();
    writer.Flush();
    }

output in books.xml is

<book>
.....
........
</book>

but I wanna output

<book key="A">
....
...
...
</book>

Just this. nothing else.

How to do this?

Well, like most computer programs it will only do what it is coded to do. If you want to add an attribute to an element then you need to add the code at the appropriate point. If you don't want the other elements in the file then don't write them. The documentation[^] shows all the appropriate method details.

Assuming you want to add an attribute to the book element use the XmlWriter.WriteAttributeString Method (String, String)[^].

So add to your code:

C#

writer.WriteAttributeString( "key", "A" );
