actively resetting cache of web a method

[mmuurman]

Hello,

I am trying to reset the cache of a web method from code like this:

[WebMethod(CacheDuration=100)]
public DateTime TheTime()
{
return DateTime.Now;
}
[WebMethod]
public void ResetCache()
{
System.Reflection.MethodInfo mi = GetType().GetMethod("TheTime");
object [] attributes = mi.GetCustomAttributes(false);
foreach( object objAttribute in attributes)
{
if( objAttribute is WebMethodAttribute)
{
WebMethodAttribute webmethodAttribute =
(WebMethodAttribute)objAttribute;
webmethodAttribute.CacheDuration = 0;
//webmethodAttribute.CacheDuration =100;
}
}
}

My ResetCache() method should enforce the TheTime() method to reset but
this doesn't work. Does anybody know how to reset/flush the cache of a
web method from code?

Greetings,
Martijn Muurman

I believe that in order to do this you have to use the Context.Cache
(System.Web.Caching.Cache) object to cache the data as opposed to the result
of the method call ...

You can even provide a dependency object to that cache.
