序言
本篇從.Net如何接入Reis開始，直至.Net對Redis的各種操作，為了方便學習與做為文件的檢視，我做一遍註釋展現，其中會對list的阻塞功能和事務的運用做二個案例，進行記錄學習。
Redis官方推薦的.NET驅動類庫為Service.Stack.Redis。然而網上對這個類庫的中文文件不是很全面與合理，這篇文章主要就對這個類庫做註釋展現。不足遺漏之處還望見諒，海涵。
.Net使用Redis是非常方便與快捷與簡單的，下面就讓我展示下吧。
這裡有必要說一下，如果你對Redis 中的基本物件資料型別還不瞭解，建議你看下我的前幾篇Redis文章，保證要到病除。點選：我的Redis系列文章
專案中安裝下載Service.Stack.Redis類庫
右擊專案->管理NuGet程式包->在聯機中輸入Reis就能出現這個類庫，然後新增引入就行啦。
.Net連結Redis資料庫，支援讀寫分離
1、配置檔案
public sealed class RedisConfig : ConfigurationSection { public static RedisConfig GetConfig() { RedisConfig section = GetConfig("RedisConfig"); return section; } public static RedisConfig GetConfig(string sectionName) { RedisConfig section = (RedisConfig)ConfigurationManager.GetSection(sectionName); if (section == null) throw new ConfigurationErrorsException("Section " + sectionName + " is not found."); return section; } /// <summary> /// 可寫的Redis連結地址 /// </summary> [ConfigurationProperty("WriteServerConStr", IsRequired = false)] public string WriteServerConStr { get { return (string)base["WriteServerConStr"]; } set { base["WriteServerConStr"] = value; } } /// <summary> /// 可讀的Redis連結地址 /// </summary> [ConfigurationProperty("ReadServerConStr", IsRequired = false)] public string ReadServerConStr { get { return (string)base["ReadServerConStr"]; } set { base["ReadServerConStr"] = value; } } /// <summary> /// 最大寫連結數 /// </summary> [ConfigurationProperty("MaxWritePoolSize", IsRequired = false, DefaultValue = 5)] public int MaxWritePoolSize { get { int _maxWritePoolSize = (int)base["MaxWritePoolSize"]; return _maxWritePoolSize > 0 ? _maxWritePoolSize : 5; } set { base["MaxWritePoolSize"] = value; } } /// <summary> /// 最大讀連結數 /// </summary> [ConfigurationProperty("MaxReadPoolSize", IsRequired = false, DefaultValue = 5)] public int MaxReadPoolSize { get { int _maxReadPoolSize = (int)base["MaxReadPoolSize"]; return _maxReadPoolSize > 0 ? _maxReadPoolSize : 5; } set { base["MaxReadPoolSize"] = value; } } /// <summary> /// 自動重啟 /// </summary> [ConfigurationProperty("AutoStart", IsRequired = false, DefaultValue = true)] public bool AutoStart { get { return (bool)base["AutoStart"]; } set { base["AutoStart"] = value; } } /// <summary> /// 本地快取到期時間，單位:秒 /// </summary> [ConfigurationProperty("LocalCacheTime", IsRequired = false, DefaultValue = 36000)] public int LocalCacheTime { get { return (int)base["LocalCacheTime"]; } set { base["LocalCacheTime"] = value; } } /// <summary> /// 是否記錄日誌,該設定僅用於排查redis執行時出現的問題,如redis工作正常,請關閉該項 /// </summary> [ConfigurationProperty("RecordeLog", IsRequired = false, DefaultValue = false)] public bool RecordeLog { get { return (bool)base["RecordeLog"]; } set { base["RecordeLog"] = value; } } }
2、配置Redis連結
public class RedisManager { /// <summary> /// redis配置檔案資訊 /// </summary> private static RedisConfig RedisConfig = RedisConfig.GetConfig(); private static PooledRedisClientManager prcm; /// <summary> /// 靜態構造方法，初始化連結池管理物件 /// </summary> static RedisManager() { CreateManager(); } /// <summary> /// 建立連結池管理物件 /// </summary> private static void CreateManager() { string[] WriteServerConStr = SplitString(RedisConfig.WriteServerConStr, ","); string[] ReadServerConStr = SplitString(RedisConfig.ReadServerConStr, ","); prcm = new PooledRedisClientManager(ReadServerConStr, WriteServerConStr, new RedisClientManagerConfig { MaxWritePoolSize = RedisConfig.MaxWritePoolSize, MaxReadPoolSize = RedisConfig.MaxReadPoolSize, AutoStart = RedisConfig.AutoStart, }); } private static string[] SplitString(string strSource, string split) { return strSource.Split(split.ToArray()); } /// <summary> /// 客戶端快取操作物件 /// </summary> public static IRedisClient GetClient() { if (prcm == null) CreateManager(); return prcm.GetClient(); } }
3、IRedisClient為操作Redis的介面，是.Net操作Redis的主要類庫，這裡我們把它接入
