HttpRuntime.Cache.Remove doesn't remove cache

Question

I am trying to remove the cache using the HttpRuntime.Cache.Remove(key) but invain. I wonder what are the best practices for using HttpRuntime.Cache.

Answer 1

The Remove method works perfectly fine and removes the item from the cache given its key. Here's an example:

class Program
{
    static void Main()
    {
        // add an item to the cache
        HttpRuntime.Cache["foo"] = "bar";
        Console.WriteLine(HttpRuntime.Cache["foo"]); // prints bar

        // remove the item from the cache
        HttpRuntime.Cache.Remove("foo");
        Console.WriteLine(HttpRuntime.Cache["foo"]); // prints empty string
    }
}

It's probably the way you are using it that is wrong. Unfortunately this hasn't been specified in your question so that's as far as we can help.
