How to show hyperlink inside AboutBox description field

Here you can use the WinForms control to achieve the desired result: LinkLabel

.

Just add it to your AboutBox layout and double click it. A handler will be created for the LinkClicked event and then you can use Process.Start

to open your website url.

public AboutBox1()
{
    InitializeComponent();
    this.Text = String.Format("About {0}", AssemblyTitle);
    this.labelProductName.Text = AssemblyProduct;
    this.labelVersion.Text = String.Format("Version {0}", AssemblyVersion);
    this.labelCopyright.Text = AssemblyCopyright;
    this.labelCompanyName.Text = AssemblyCompany;
    this.textBoxDescription.Text = AssemblyDescription;
    this.Link.Text = "Visit our website!";
    this.Link.Tag = WpfApplication2.Properties.Resources.website;
}

private void Link_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
    System.Diagnostics.Process.Start((sender as LinkLabel).Tag.ToString());
}

      

        
        
        
      

    

In my case, I saved the URL as an application resource. And I showed this separately from the assembly description.

If you want the link to appear inside the assembly description, this is pretty tricky ...
