Searching in XML

[C# Programming]

hi all http://www.barakasoft.com/script/Forums/Images/smiley_biggrin.gif ,

my query as following
var result = (from page in xmlDoc.Descendants("Page")
from id in page.Descendants("User")
select new
{
Name = page.Element("Name").Value,
ID = id.Element("ID").Value,
View = id.Element("View").Value,
Add = id.Element("Add").Value,
Edit = id.Element("Edit").Value,
Delete = id.Element("Delete").Value,
Grant = id.Element("Grant").Value,
UserID = id.Element("UserID").Value,
LoginID = id.Element("LoginID").Value
}).Distinct().Where(t => t.LoginID.StartsWith(LoginID) && t.Name == Name).ToList();

return result;

above query is working well......but it is case sensitive http://www.barakasoft.com/script/Forums/Images/smiley_sigh.gif
i don't know where is problem........
