文本块内的HyperlinkBut​​ton

Question

There is some text that i want to take from JSON file:

"text":"evqvqgqegweg<br>wegewg<br>e<br>ewgewg<br>ewg<br>http:\/\/f.com<br>egewg"

How can I detect the link and parse it to the textblock with HyperlinkButton ?

Thanks in advance!

You can use a simple regular expression to pick out your links: http:.*[.com|.co.uk] This will of course also parse any escape characters: http:\\/\\/f.com .

You can use it like this:

Match match = Regex.Match(inputTextString, "http:.*[.com|.co.uk]");
if (match.Success) PublicLinkProperty = new Uri(match.Value);

Where PublicLinkProperty is a property on your view model/code behind:

// you should implement the INotifyPropertyChanged interface on this property
public Uri PublicLinkProperty { get; set; }

You can then use that property to Bind to the HyperlinkButton.NavigateUri property:

<HyperlinkButton Content="Click here" NavigateUri="{Binding PublicLinkProperty}" 
    TargetName="_blank" />

Note that this regular expression will pick out anything that starts with http: and ends with either .com or .co.uk .
