Re: how to clear cache in asp.net

hi,

You can clear cache by using the following code,

public void ClearApplicationCache(){
    List<string> keys = new List<string>();
    // retrieve application Cache enumerator
    IDictionaryEnumerator enumerator = Cache.GetEnumerator();
    // copy all keys that currently exist in Cache
    while (enumerator.MoveNext()){
        keys.Add(enumerator.Key.ToString());
    }
    // delete every key from cache
    for (int i = 0; i < keys.Count; i++) {
        Cache.Remove(keys[i]);
    }
}

Hi,

You can try to use HttpRuntime.Close().

Hi. Do I have to erase my previous code or I will just add this "HttpRuntime.Close()" after?

Below is my code:

public void ClearApplicationCache()
        {
            List<string> keys = new List<string>();

            IDictionaryEnumerator enumerator = Cache.GetEnumerator();

            while (enumerator.MoveNext())
            {
                keys.Add(enumerator.Key.ToString());
            }

            for (int i = 0; i < keys.Count; i++)
            {
                Cache.Remove(keys[i]);
            }
        }

Thanks.
