Programmatically Refresh DNS resolution (avoid cache) (c#)

Question

Hi all,

Is there a way to programmatically remove an address from windows' dns cache, or to re-resolve it? I'm using c#, but native code would be just fine (however, playing with the registry would not be). I'm writing a little application that measures the amount of time it takes to resolve an address and would like to avoid caching issues.

thanks!
