c# - How to use LINQ to determine if specific attribute value exists? -

i programming in c# , working xdocument. want add element tree if , if there no other elements have matching attribute value.

for example, there linq expression can use @ element below , see if there exists foo element same name before add it?

<people>     <foo name="bob"> </foo>     <foo name="larry"></foo>     <foo name="tom"></foo> </people>

i want this...

while(myxdocument.element("people").elements("foo").attribute("name").contains(myname)) {     // modify myname , try again... }

this should work:

xelement.any(element => element.attribute("name").value == myname)

it return true if there's attribute name equals myname
