You can use the username string we retrieved above to programmatically output the username to a page however you want.  For example, you could easily add an <asp:label> control to the page and write code like so to set it:

Label1.Text = "Welcome " & User.Identity.Name

ASP.NET 2.0 also ships with a built-in <asp:LoginName> control that you can use to declaratively output the user-name to the page:

<asp:LoginName ID="LoginName1" FormatString="Welcome {0}!" runat="server" />

This control provides an easy way to display the username within the application without having to write any code at all (note the use of the “FormatString” property on the control above – which allows you to easily specify a text mask to use with it).
