Hiding an email address in string

I am building a string in which I have to hide an email address.

string StatusText = "Please reach out here for access."

Just wanted to know how can we hide an email address in a string. I'd like the "here" to be an email address. I have to bind StatusText to a Textblock such that when user clicks on "here", the outlook mail should open.

Here's the detailed code:

View.xaml

<TextBlock   Text="{Binding StatusText}" />

ViewModel.cs

private string _statusText;
public string StatusText
{
            get { return _statusText; }
            set { SetProperty(ref _statusText, value); }
}


DisplayMessages()
{
  //based on the boolean value, Status Text is set
  //When the case is "NoAccess", I want the "here" of StatusText to be clickable and show the mailaddress as [email protected]
  switch(Flag)
   case IsReady:
       StatusText = "Application is Ready";
     break;
   case NoAccess:
     StatusText = "Please reach out here. No access can be provided."
    break;
}

Step 1: Add the following XAML code inside Window.Resources.

<local:DataTemplateSelectorExt x:Key="Selector"></local:DataTemplateSelectorExt>

<DataTemplate x:Key="NoAccess">
        <TextBlock Background="Green">
            <Run Text="Please reach out "/>
            <Hyperlink NavigateUri="[email protected]" RequestNavigate="Hyperlink_RequestNavigate">here</Hyperlink>
            <Run Text=" for access."/>
        </TextBlock>
    </DataTemplate>

Step 2: Replace TextBlock XAML code with the following code snippet.

<Label Content="{Binding StatusText}" ContentTemplateSelector="{Binding Source={StaticResource Selector}}" />

Step 3: Add the following method inside MainWindow class.

private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
    {
        Popup popup = new Popup { IsOpen = true, Width = 100, Height = 50, Placement = PlacementMode.Mouse };
        popup.Child = new TextBlock { Text = (sender as Hyperlink).NavigateUri.ToString(), Background = Brushes.Green };
        popup.IsOpen = true;            
    }

Step 4: Finally add the below class in your project.

public class DataTemplateSelectorExt : DataTemplateSelector
{
    public override DataTemplate SelectTemplate(object item, DependencyObject container)
    {
        if (item == null) return (DataTemplate)null;

        FrameworkElement frameworkElement = container as FrameworkElement;

        if (item.Equals("Please reach out here. No access can be provided."))
            return Application.Current.MainWindow.FindResource("NoAccess") as DataTemplate;

            return null;
    }
}

Hope, this will meet your requirement.

I would you to take advantage of XAML.

<TextBlock>
    <Run Text="Please reach out "/>
    <Hyperlink NavigateUri="YOUR_URL_FOR_OUTLOOK" RequestNavigate="Hyperlink_RequestNavigate">here</Hyperlink>
    <Run Text=" for access."/>
</TextBlock>

In code behind

private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
    Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
    e.Handled = true;
}

The main benefit of using this approach is that you can use Binding to bind your emailId to Hyperlink.

Your output will look like this in Viewer enter image description here
