推荐答案

ASP.NET带有非常强大的缓存机制，可用于轻松提高响应速度和效率.您的Web应用程序.

这是清除Web应用程序中所有缓存数据的代码片段:

ASP.NET comes with very powerful caching mechanism that can be used to easily improve responsiveness and efficiency of your web applications.

Here is the code snippet that clears all cached data in your web application:

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]);
    }
}
