c#Cache的用法

public class Cache
{
///

/// 获取数据缓存
///

/// 键
public static object GetCache(string cacheKey)
{
var objCache = HttpRuntime.Cache.Get(cacheKey);
return objCache;
}
///

/// 设置数据缓存
///

public static void SetCache(string cacheKey, object objObject)
{
var objCache = HttpRuntime.Cache;
objCache.Insert(cacheKey, objObject);
}
///

/// 设置数据缓存
///

public static void SetCache(string cacheKey, object objObject, int timeout = 7200)
{
try
{
if (objObject == null) return;
var objCache = HttpRuntime.Cache;
//相对过期
//objCache.Insert(cacheKey, objObject, null, DateTime.MaxValue, timeout, CacheItemPriority.NotRemovable, null);
//绝对过期时间
objCache.Insert(cacheKey, objObject, null, DateTime.Now.AddSeconds(timeout), TimeSpan.Zero, CacheItemPriority.High, null);
}
catch (Exception)
{
//throw;
}
}
///

/// 移除指定数据缓存
///

public static void RemoveAllCache(string cacheKey)
{
var cache = HttpRuntime.Cache;
cache.Remove(cacheKey);
}
///

/// 移除全部缓存
///

public static void RemoveAllCache()
{
var cache = HttpRuntime.Cache;
var cacheEnum = cache.GetEnumerator();
while (cacheEnum.MoveNext())
{
cache.Remove(cacheEnum.Key.ToString());
}
}
}
