Create A XML doc

[scriptick]

I use this code -

 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 pavel.xml is 

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

but I wanna output 

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

Just this. nothing else.

How to do this?

Those extra pieces of information found in the opening tags of XML are called attributes. You need to look into the WriteAttributeS tring method of XmlWriter.

After your line 10 you would need an extra line of code like this:

writer.WriteStartElement( "book" );
writer.WriteAttributeString("Key", "A");

Check out the documentation here (MSDN documentation for WriteAttributeS tring)
