[DotNetDevelopment] Query a Generated Class Using LINQ c#

[Ms C]

I have this xml:

<Customers>
        <CustomerDetail>
                <CustomerFormofPayment Amount="200.00" Code="USD">
                        <Billing>
                                <Address>
                                        <FirstName>Test1</FirstName>
                                        <LastName>Test2</LastName>
                                </Address>
                                <TID>1234568</TID>
                        </Billing>
                </CustomerFormofPayment>
        </CustomerDetail>
                <CustomerInfo>
                        <Name>
                                <GivenName>test</GivenName>
                                <MiddleName></MiddleName>
                                <Surname>testing</Surname>
                        </Name>
                        <Address>
                                <AddressLine>222 Elm Street</AddressLine>
                                <AddressLine></AddressLine>
                                <CityName>Anycity</CityName>
                                <StateProv>XX</StateProv>
                                <CountryName>US</CountryName>
                        </Address>
                        <Telephone PhoneNumber="111-222-3333"></Telephone>
                        <Email>t...@u.com</Email>
                </CustomerInfo>
</Customers>

I used the xsd from this xml to generate a class.  I am trying to
query the generated class
using LINQ to create an object.  My problem is that the element
<CustomerDetail> has two other choices that could have been selected.
Now the tag <Item> is generated in the class. Is there a way I can
select all the elements with this class and then create a query using
LINQ to generated an object?
