Personal project framework construction and project framework construction

1. cache Interface

using System;using System.Collections.Generic;using System.Runtime.Caching;using System.Text.RegularExpressions;namespace EnterpriseFrame.Core.Caching{    /// <summary>    /// Represents a manager for caching between HTTP requests (long term caching)    /// </summary>    public partial class MemoryCacheManager : ICacheManager    {        protected ObjectCache Cache        {            get            {                return MemoryCache.Default;            }        }                /// <summary>        /// Gets or sets the value associated with the specified key.        /// </summary>        /// <typeparam name="T">Type</typeparam>        /// <param name="key">The key of the value to get.</param>        /// <returns>The value associated with the specified key.</returns>        public virtual T Get<T>(string key)        {            return (T)Cache[key];        }        /// <summary>        /// Adds the specified key and object to the cache.        /// </summary>        /// <param name="key">key</param>        /// <param name="data">Data</param>        /// <param name="cacheTime">Cache time</param>        public virtual void Set(string key, object data, int cacheTime)        {            if (data == null)                return;            var policy = new CacheItemPolicy();            policy.AbsoluteExpiration = DateTime.Now + TimeSpan.FromMinutes(cacheTime);            Cache.Add(new CacheItem(key, data), policy);        }        /// <summary>        /// Gets a value indicating whether the value associated with the specified key is cached        /// </summary>        /// <param name="key">key</param>        /// <returns>Result</returns>        public virtual bool IsSet(string key)        {            return (Cache.Contains(key));        }        /// <summary>        /// Removes the value with the specified key from the cache        /// </summary>        /// <param name="key">/key</param>        public virtual void Remove(string key)        {            Cache.Remove(key);        }        /// <summary>        /// Removes items by pattern        /// </summary>        /// <param name="pattern">pattern</param>        public virtual void RemoveByPattern(string pattern)        {            var regex = new Regex(pattern, RegexOptions.Singleline | RegexOptions.Compiled | RegexOptions.IgnoreCase);            var keysToRemove = new List<String>();            foreach (var item in Cache)                if (regex.IsMatch(item.Key))                    keysToRemove.Add(item.Key);            foreach (string key in keysToRemove)            {                Remove(key);            }        }        /// <summary>        /// Clear all cache data        /// </summary>        public virtual void Clear()        {            foreach (var item in Cache)                Remove(item.Key);        }    }}

2. Expansion

Using System; namespace using iseframe. core. caching {/// <summary> /// Extensions // </summary> public static class CacheExtensions {/// <summary> /// obtain the cache, if the acquire result does not exist, it is saved to the cache, the default time is 60 Minutes. // </summary> // <typeparam name = "T"> Type </typeparam> // <param name = "cacheManager"> Cache manager </param> /// <param name = "key"> Cache key </param> /// <param name = "acquire"> Function to load item if it's not in the cache yet </param> // <returns> Cached item </returns> public static T Get <T> (this ICacheManager cacheManager, string key, Func <T> acquire) {return Get (cacheManager, key, 60, acquire) ;}/// <summary> /// obtain the cache. If no cache exists, load and cache the execution result. /// </summary> /// <typeparam name = "T"> cache type </typeparam> /// <param name =" cacheManager "> Cache manager </param> /// <param name =" key "> Cache key </param> /// <param name =" cacheTime "> the Cache time is 0 minutes-do not cache </param> /// <param name = "acquire"> if no cache exists, execute this expression to set the cache </param> /// <returns> Cached item </returns> public static T Get <T> (this ICacheManager cacheManager, string key, int cacheTime, Func <T> acquire) {if (cacheManager. isSet (key) {return cacheManager. get <T> (key) ;}else {var result = acquire (); if (cacheTime> 0) cacheManager. set (key, result, cacheTime); return result ;}}}}

 

3. MemoryCacheManager implementation

using System;using System.Collections.Generic;using System.Runtime.Caching;using System.Text.RegularExpressions;namespace EnterpriseFrame.Core.Caching{    /// <summary>    /// Represents a manager for caching between HTTP requests (long term caching)    /// </summary>    public partial class MemoryCacheManager : ICacheManager    {        protected ObjectCache Cache        {            get            {                return MemoryCache.Default;            }        }                /// <summary>        /// Gets or sets the value associated with the specified key.        /// </summary>        /// <typeparam name="T">Type</typeparam>        /// <param name="key">The key of the value to get.</param>        /// <returns>The value associated with the specified key.</returns>        public virtual T Get<T>(string key)        {            return (T)Cache[key];        }        /// <summary>        /// Adds the specified key and object to the cache.        /// </summary>        /// <param name="key">key</param>        /// <param name="data">Data</param>        /// <param name="cacheTime">Cache time</param>        public virtual void Set(string key, object data, int cacheTime)        {            if (data == null)                return;            var policy = new CacheItemPolicy();            policy.AbsoluteExpiration = DateTime.Now + TimeSpan.FromMinutes(cacheTime);            Cache.Add(new CacheItem(key, data), policy);        }        /// <summary>        /// Gets a value indicating whether the value associated with the specified key is cached        /// </summary>        /// <param name="key">key</param>        /// <returns>Result</returns>        public virtual bool IsSet(string key)        {            return (Cache.Contains(key));        }        /// <summary>        /// Removes the value with the specified key from the cache        /// </summary>        /// <param name="key">/key</param>        public virtual void Remove(string key)        {            Cache.Remove(key);        }        /// <summary>        /// Removes items by pattern        /// </summary>        /// <param name="pattern">pattern</param>        public virtual void RemoveByPattern(string pattern)        {            var regex = new Regex(pattern, RegexOptions.Singleline | RegexOptions.Compiled | RegexOptions.IgnoreCase);            var keysToRemove = new List<String>();            foreach (var item in Cache)                if (regex.IsMatch(item.Key))                    keysToRemove.Add(item.Key);            foreach (string key in keysToRemove)            {                Remove(key);            }        }        /// <summary>        /// Clear all cache data        /// </summary>        public virtual void Clear()        {            foreach (var item in Cache)                Remove(item.Key);        }    }}
