Question

So, I want to create an Uri from user input.
I have a textbox, an Ok button and web browser control.

User writes his desired web address, clicks button and launches getUri method.

I tried to create something like this:

private void ok_tap(object sender, System.Windows.Input.GestureEventArgs e)
{
    Uri address = new Uri(AdressBox.Text, UriKind.Absolute);
    web.Navigate(address);
}

Aaand it works quite allright. However, only when user types adress with “http://”. Problem is: no one writes whole links, and with just “google.com” app crashes.

i could check if there is something like “http” in user input and add it manually… but it feels like I try to reinvent the wheel.

Use the UriBuilder class. Its String constructor defaults to HTTP protocol:

private void ok_tap(object sender, System.Windows.Input.GestureEventArgs e)
{
    Uri address = new UriBuilder(AdressBox.Text).Uri;
    web.Navigate(address);
}
