[SOLVED] VB.Net Webview2 How can I get html source code?

VB.Net Webview2 How can I get html source code?

I sucessfully display a web site on WebView2 in my VB.net (Visual Studio 2017) project but can not get html souce code. Please advise me how to get html code.

My code:

Private Sub testbtn_Click(sender As Object, e As EventArgs) Handles testbtn.Click
        WebView2.CoreWebView2.Navigate("https://www.microsoft.com/")
End Sub

Private Sub WebView2_NavigationCompleted(sender As Object, e As CoreWebView2NavigationCompletedEventArgs) Handles WebView2.NavigationCompleted
        Dim html As String = ?????
End Sub

Thank you indeed for your advise in advance.

Solution

I've only just started messing with the WebView2 earlier today as well, and was just looking for this same thing. I did manage to scrape together this solution:

Dim html As String
html = Await WebView2.ExecuteScriptAsync("document.documentElement.outerHTML;")

' The Html comes back with unicode character codes, other escaped characters, and
' wrapped in double quotes, so I'm using this code to clean it up for what I'm doing.
html = Regex.Unescape(html)
html = html.Remove(0, 1)
html = html.Remove(html.Length - 1, 1)

Converted my code from C# to VB on the fly, so hopefully didn't miss any syntax errors.
