thank , devin magaro

currently you're creating new element using document, never adding document. you're trying set attribute had text within element itself.

assuming want update element, i'd use linq xml instead of xmldocument:

var doc = xdocument.load("version.xml"); // single() ensures there's 1 such element var element = doc.descendants("product").single();  int currentvalue = (int) element; element.setvalue(currentvalue + 1); doc.save("version.xml"); 

if want update all product elements, should loop on doc.descendants("product") foreach loop.
