(VB.NET UWP/WinRT) Upload Files to a Web Server - Simplest Example

This is the simplest example for uploading some files to a web server. the BlockingUpload call is synchronous and returns when the upload is finished (or failed).

A server-side C# example showing how to receive an upload is located at C# ASP.NET Code to Receive Upload

Dim upload As New Chilkat.Upload

' Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
' that will receive and process the HTTP Upload.
upload.Hostname = "www.mywebserver.com"
upload.Path = "/receiveUpload.aspx"

' Add one or more files to be uploaded.
upload.AddFileReference("file1","dude.gif")
upload.AddFileReference("file2","swordfish.xml")
upload.AddFileReference("file3","sample.doc")

' Do the upload.  The method returns when the upload
' is completed.
' This component also includes asynchronous upload capability,
' which is demonstrated in another example.
Dim success As Boolean = Await upload.BlockingUploadAsync()
If (success <> True) Then
    Debug.WriteLine(upload.LastErrorText)
Else
    Debug.WriteLine("Files uploaded!")
End If
