Question

Hello i am developing application for windows phone and i want to read an xml from the web
so i am using on page loaded event :

Dim cl As New WebClient
AddHandler cl.DownloadStringCompleted, AddressOf cl_DownloadStringCompleted
cl.DownloadStringAsync(New Uri("demo.com/1.xml",UriKind.RelativeOrAbsolute))

and on cl.DownloadStringCompleted event :

Dim doc = XDocument.Load("demo.com/1.xml")

but for some reason i crashes !
the bug must be that i have not to use URI : “demo.com/1.xml” , but some else :S

Answer 1

The DownloadStringCompleted event has DownloadStringCompletedEventArgs. You should use the Result property of those args.

Dim client As New WebClient()
AddHandler client.DownloadStringCompleted, AddressOf ClientOnDownloadStringCompleted
client.DownloadStringAsync(New Uri("http://demo.com/xml"))

and the handler:

Private Sub ClientOnDownloadStringCompleted(sender As Object, args As DownloadStringCompletedEventArgs)
    Dim doc = XDocument.Parse(args.Result)
End Sub
