代碼如下:
using System.Collections.Generic;
using System.Web;
using System;
namespace DataAccess
{
/// <summary>
/// 緩存控制類
/// </summary>
public class CacheControl
{
public static List<string> AllUseCacheKey = new List<string>();
/// <summary>
/// 添加緩存
/// </summary>
/// <param name="key"></param>
/// <param name="value"></param>
/// <param name="absoluteExpiration"></param>
public static void AddCache(string key, object value, DateTime absoluteExpiration)
{
if (!AllUseCacheKey.Contains(key))
{
AllUseCacheKey.Add(key);
}
HttpContext.Current.Cache.Add(key, value, null, absoluteExpiration, TimeSpan.Zero, System.Web.Caching.CacheItemPriority.Normal, null);
}
/// <summary>
/// 移除緩存
/// </summary>
/// <param name="key"></param>
public static void RemoveCache(string key)
{
if (AllUseCacheKey.Contains(key))
{
AllUseCacheKey.Remove(key);
}
HttpContext.Current.Cache.Remove(key);
}
/// <summary>
/// 清空使用的緩存
/// </summary>
public static void ClearCache()
{
foreach (string value in AllUseCacheKey)
{
HttpContext.Current.Cache.Remove(value);
}
AllUseCacheKey.Clear();
}
}
}
