public static class SampleDataCache
{
    private static Dictionary<string,SampleData> cacheDict = new Dictionary<string,object>()
 
    public static Get(string key)
    {
        if(!cacheDict.Contains[key])
            cacheDict.Add(key,new SampleData());
 
        return cacheDict[key];
    }
}

当我刷新页面时,我希望SampleDataCache保留其数据.

我能以简单的方式实现这一目标吗？
