ASP.NET

I have a System.Collections.Generic.Dictionary<System.Web.UI.Control, object> where all keys can be either type of System.Web.UI.WebControls.HyperLink or type of System.Web.UI.WebControls.Label.

I want to change Text property of each control. Because HyperLink doesn't implement (why??) ITextControl, I need to cast Label or HyperLink explicitly:

Dictionary<Control,object> dic = ..

dic
  .Where(p => p.Key is HyperLink)
  .ForEach(c => ((HyperLink)c).Text = "something")

dic
  .Where(p => p.Key is Label)
  .ForEach(c => ((Label)c).Text = "something")

Are there ways to workaround such approach?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
