Net使用Redis详解之ServiceStack.Redis（七）
序言
本篇从.Net如何接入Reis开始，直至.Net对Redis的各种操作，为了方便学习与做为文档的查看，我做一遍注释展现，其中会对list的阻塞功能和事务的运用做二个案例，进行记录学习。
Redis官方推荐的.NET驱动类库为Service.Stack.Redis。然而网上对这个类库的中文文档不是很全面与合理，这篇文章主要就对这个类库做注释展现。不足遗漏之处还望见谅，海涵。
.Net使用Redis是非常方便与快捷与简单的，下面就让我展示下吧。
这里有必要说一下，如果你对Redis 中的基本对象数据类型还不了解，建议你看下我的前几篇Redis文章，保证要到病除。点击：我的Redis系列文章
项目中安装下载Service.Stack.Redis类库
右击项目->管理NuGet程序包->在联机中输入Reis就能出现这个类库，然后添加引入就行啦。
.Net链接Redis数据库，支持读写分离
1、配置文件
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>

/// </summary>
[ConfigurationProperty("WriteServerConStr", IsRequired = false)]
public string WriteServerConStr
{
get
{
return (string)base["WriteServerConStr"];
}
set
{
base["WriteServerConStr"] = value;
}
}
/// <summary>
/// 可读的Redis链接地址
/// </summary>
[ConfigurationProperty("ReadServerConStr", IsRequired = false)]
public string ReadServerConStr
{
get
{

}
set
{

}
}
/// <summary>

/// </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>

return _maxReadPoolSize > 0 ? _maxReadPoolSize : 5;
}
set
{

}
}
/// <summary>

{

{
return (bool)base["AutoStart"];
}

{

}
}
/// <summary>

}
}

}
}
}
2、配置Redis链接
public class RedisManager
{
/// <summary>

/// </summary>
private static RedisConfig RedisConfig = RedisConfig.GetConfig();
private static PooledRedisClientManager prcm;
/// <summary>

}
/// <summary>

private static void CreateManager()
{

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、IRedisClient为操作Redis的接口，是.Net操作Redis的主要类库，这里我们把它接入
/// <summary>

{
public static IRedisClient Core { get; private set; }

static RedisBase()
{

}

{
if (!this._disposed)
{
if (disposing)
{
Core.Dispose();
Core = null;
}
}
this._disposed = true;
}
public void Dispose()
{
Dispose(true);
GC.SuppressFinalize(this);
}
