The following example declares a string variable named urlConverted, and sets it to the result of an ApplyAppPathModifier method call. The code then passes the variable's value to a HyperLink control's NavigateUrl property.

// Declare a string variable and set it to the result 
// of a call to the ApplyAppPathModifier method. 
// Then set the NavigateUrl property of a Hyperlink control 
// to the string's value.
string urlConverted = Response.ApplyAppPathModifier("TestPage.aspx");
hlTest1.NavigateUrl = urlConverted;
