Pulling first values from xml file in c#

I have an xml file that starts with:


<SAMPLEPROFILE
    Name="File Name"
    Number="2"
    >

I am trying to pull out the Number.

Here is what I am trying:


string number = _myXml.GetElementsByTagName("SAMPLEPROFILE").Item(1).Value;

When debugging I can see the xml file by hovering over _myXml, but I cannot see the number property?
