public void 缓存壳()
{
//不加缓存的时候，要从数据库查询
string str1 = "val";
//1一般的缓存代码，如不封装还挺繁琐的
var cacheValue = rds.Get("test1");
if (!string.IsNullOrEmpty(cacheValue))
{
try
{
var obj = JsonConvert.DeserializeObject(cacheValue);
}
catch
{
//出错时删除key
rds.Del("test1");
throw;
}
}
rds.Set("test1", JsonConvert.SerializeObject(str1), 10); //缓存10秒
//2使用缓存壳效果同上，以下示例使用 string 和 hash 缓存数据
var t1 = rds.CacheShell("test1", 10, () => str1);
var t2 = rds.CacheShell("test", "1", 10, () => str1);
var t3 = rds.CacheShell("test", new[] { "1", "2" }, 10, notCacheFields => new[] { ("1", str1), ("2", str1) });
