c# - 在里面选择带有 if 语句的 new

Question

我有这段代码可以从我的 C# 项目的数据库中选择一些新的信息，但我只希望它在名称不是特定名称时执行，所以这里是代码

public List<Info> GetInfo(int id)
{
    var cacheKey = "allinfo-" + id;
    var info = SoftCache.GetData<List<info>>(cacheKey);
    if (info != null)
        return info;

    using (var db = DB.InfoModel)
    {
        info = (from j in db.info_list()

                select new Info
                {
                    InfoName = j.info_name,
                    InfoId = j.info_id,
                    InfoValue = j.info_value,
                }).ToList();
    }

    SoftCache.Add(cacheKey, info, new TimeSpan(0, 0, 5), new TimeSpan(0, 1, 0));
    return info;
}

我想要的是类似的东西

if(j.info_name != "BadName"){
    select new Info
    {
        InfoName = j.info_name,
        InfoId = j.info_id,
        InfoValue = j.info_value,
    }).ToList();
}

您需要添加一个 where声明在这里:

info = (from j in db.info_list()
where j.info_name != "BadName"
select new Info
{
    InfoName = j.info_name,
    InfoId = j.info_id,
    InfoValue = j.info_value,
}).ToList();
