篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了C# Redis之ServiceStack相关的知识，希望对你有一定的参考价值。
前面几篇博客基本把redis基本操作学习了下，但一些高级应用并没有写进博客，例如持久化、虚拟内存等，像这些主要是通过配置文件来解决的，运维方向可能更侧重一些，对于开发者来说，可能就想知道怎么用C#来和Redis服务器打交道，今天使用的ServiceStack就是用来做这事的。
一、引入ServiceStack
通过NuGET搜索ServiceStack，安装之后会有4个dll，如下图
二、启动Redis服务
这里按照上一篇博客主从复制的结果搭建Redis服务器。6379的是主服务器，6380的是从服务器。图我就不截了，上篇博客中已经有了。
三、封装帮助类
关于ServiceStack的帮助类也挺多的，我在这博客贴出来的类也是从网上搜的，只是在它的基础上进行了下修改，比如配置RedisConfig.cs文件，我这里直接返回一个定值，这主要是测试，如果在开发中，应该写在配置文件中。这里我新建了一个RedisHelper的文件夹来存放这些帮助类。
1.配置文件 主要配置服务器的一些参数 读写服务器地址 最大的读写数量等
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Configuration; namespace RedisHelper { public sealed class RedisConfig : ConfigurationSection { public static string WriteServerConStr{ get { return string.Format("{0},{1}","127.0.0.1:6379","127.0.0.1:6380"); } } public static string ReadServerConStr { get { return string.Format("{0}", "127.0.0.1:6379"); } } public static int MaxWritePoolSize { get { return 50; } } public static int MaxReadPoolSize { get { return 200; } } public static bool AutoStart { get { return true; } } } }
2.RedisManager管理类 主要管理维护服务端访问类
using ServiceStack.Redis; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RedisHelper { public class RedisManager { private static PooledRedisClientManager prcm; /// <summary> /// 静态构造方法，初始化链接池管理对象 /// </summary> static RedisManager() { CreateManager(); } /// <summary> /// 创建链接池管理对象 /// </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> /// 客户端缓存操作对象 /// </summary> public static IRedisClient GetClient() { if (prcm == null) CreateManager(); return prcm.GetClient(); } } }
3.RedisBase类 字符串、List等操作类的基类
using ServiceStack.Redis; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RedisHelper { /// <summary> /// RedisBase类，是redis操作的基类，继承自IDisposable接口，主要用于释放内存 /// </summary> public abstract class RedisBase : IDisposable { public static IRedisClient Core { get; private set; } private bool _disposed = false; static RedisBase() { Core = RedisManager.GetClient(); } protected virtual void Dispose(bool disposing) { if (!this._disposed) { if (disposing) { Core.Dispose(); Core = null; } } this._disposed = true; } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } /// <summary> /// 保存数据DB文件到硬盘 /// </summary> public void Save() { Core.Save(); } /// <summary> /// 异步保存数据DB文件到硬盘 /// </summary> public void SaveAsync() { Core.SaveAsync(); } } }
4.字符串、List、Hash等操作类
(1)string操作类
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RedisHelper { public class RedisString : RedisBase { #region 赋值 /// <summary> /// 设置key的value /// </summary> public static bool Set(string key, string value) { return RedisBase.Core.Set<string>(key, value); } /// <summary> /// 设置key的value并设置过期时间 /// </summary> public static bool Set(string key, string value, DateTime dt) { return RedisBase.Core.Set<string>(key, value, dt); } /// <summary> /// 设置key的value并设置过期时间 /// </summary> public static bool Set(string key, string value, TimeSpan sp) { return RedisBase.Core.Set<string>(key, value, sp); } /// <summary> /// 设置多个key/value /// </summary> public static void Set(Dictionary<string, string> dic) { RedisBase.Core.SetAll(dic); } #endregion #region 追加 /// <summary> /// 在原有key的value值之后追加value /// </summary> public static long Append(string key, string value) { return RedisBase.Core.AppendToValue(key, value); } #endregion #region 获取值 /// <summary> /// 获取key的value值 /// </summary> public static string Get(string key) { return RedisBase.Core.GetValue(key); } /// <summary> /// 获取多个key的value值 /// </summary> public static List<string> Get(List<string> keys) { return RedisBase.Core.GetValues(keys); } /// <summary> /// 获取多个key的value值 /// </summary> public static List<T> Get<T>(List<string> keys) { return RedisBase.Core.GetValues<T>(keys); } #endregion #region 获取旧值赋上新值 /// <summary> /// 获取旧值赋上新值 /// </summary> public string GetAndSetValue(string key, string value) { return RedisBase.Core.GetAndSetValue(key, value); } #endregion #region 辅助方法 /// <summary> /// 获取值的长度 /// </summary> public static long GetCount(string key) { return RedisBase.Core.GetStringCount(key); } /// <summary> /// 自增1，返回自增后的值 /// </summary> public static long Incr(string key) { return RedisBase.Core.IncrementValue(key); } /// <summary> /// 自增count，返回自增后的值 /// </summary> public static double IncrBy(string key, double count) { return RedisBase.Core.IncrementValueBy(key, count); } /// <summary> /// 自减1，返回自减后的值 /// </summary> public static long Decr(string key) { return RedisBase.Core.DecrementValue(key); } /// <summary> /// 自减count ，返回自减后的值 /// </summary> /// <param name="key"></param> /// <param name="count"></param> /// <returns></returns> public static long DecrBy(string key, int count) { return RedisBase.Core.DecrementValueBy(key, count); } #endregion } }
(2)List操作类

(3)Hash操作类
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace RedisHelper { public class RedisHash : RedisBase { #region 添加 /// <summary> /// 向hashid集合中添加key/value /// </summary> public static bool SetEntryInHash(string hashid, string key, string value) { return RedisBase.Core.SetEntryInHash(hashid, key, value); } /// <summary> /// 如果hashid集合中存在key/value则不添加返回false，如果不存在在添加key/value,返回true /// </summary> public static bool SetEntryInHashIfNotExists(string hashid, string key, string value) { return RedisBase.Core.SetEntryInHashIfNotExists(hashid, key, value); } /// <summary> /// 存储对象T t到hash集合中 /// </summary> public static void StoreAsHash<T>(T t) { RedisBase.Core.StoreAsHash<T>(t); } #endregion #region 获取 /// <summary> /// 获取对象T中ID为id的数据。 /// </summary> public static T GetFromHash<T>(object id) { return RedisBase.以上是关于C# Redis之ServiceStack的主要内容，如果未能解决你的问题，请参考以下文章
