Tricky VB to C# conversion

[meerkatinfrance]

I am trying to convert some VB that uses Linq into C#
Is there anyone out there who is kind enough (clever enough) to show
me how to convert the following Sub loadAddress into C# for me.

Sub DoIt()
Dim WWV5 As New WWV5DataContext
Dim Xorg As Object

If Roles.IsUserInRole("Admin") Then
Xorg = (From o In WWV5.ORGs Where o.OrgID = ID Select o).Single
Else
Xorg = (From o In WWV5.ORGScopies Where o.OrgID = ID Select o).Single
End If
loadAddress(Xorg)
End Sub

Protected Sub loadAddress(ByRef pOrg As Object)
txtName.Text = pOrg.OrgName
txtCharNum.Text = pOrg.CharNum
txtAdd1.Text = pOrg.Add1
End Sub

Oh; one other thing; data contexts are usually disposable, so I'd
actually have something like:

using(var ctx = new WWV5DataContext()) {
Org org;
if(Roles.IsUserInRole("Admin")) {
org = ctx.ORGs.Where(o=>o.OrgID == ID).Single();
} else {
org = ctx.ORGScopies.Where(o=>o.OrgID == ID).Single();
}
LoadAddress(org);
}

Hello Marc,

Me again !
I forgot to mention that the using statement you suggestion did not
work. error:Cannot implicitly convert type 'ORGScopy' to 'ORG'

I hope you have not gone home :-)
