.Net使用Redis詳解之ServiceStack.Redis
序言
本篇從.Net如何接入Redis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。
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;

});
}

}
