  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.
