根据条件降序排列

我想编写一个 LINQ to Entity 查询，它根据输入参数按升序或降序排序，有什么办法吗？ 以下是我的代码。请建议。

    public List<Hosters_HostingProviderDetail> GetPendingApproval(SortOrder sortOrder)
    {
        List<Hosters_HostingProviderDetail> returnList = new List<Hosters_HostingProviderDetail>();
        int pendingStateId = Convert.ToInt32(State.Pending);
        //If the sort order is ascending
        if (sortOrder == SortOrder.ASC)
        {
            var hosters = from e in context.Hosters_HostingProviderDetail
                          where e.ActiveStatusID == pendingStateId
                          orderby e.HostingProviderName ascending
                          select e;
            returnList = hosters.ToList<Hosters_HostingProviderDetail>();
            return returnList;
        }
        else
        {
            var hosters = from e in context.Hosters_HostingProviderDetail
                          where e.StateID == pendingStateId
                          orderby e.HostingProviderName descending
                          select e;
            returnList = hosters.ToList<Hosters_HostingProviderDetail>();
            return returnList;
        }
    }

我认为您不能将条件放入更大的查询中，但您可以将其分离到另一个 C# 语句中，如下所示：

// Common code:
var hosters = from e in context.Hosters_HostingProviderDetail
              where e.ActiveStatusID == pendingStateId;

// The difference between ASC and DESC:
hosters = (sortOrder == SortOrder.ASC ? hosters.OrderBy(e => e.HostingProviderName) : hosters.OrderByDescending(e => e.HostingProviderName));

// More common code:
returnList = hosters.ToList<Hosters_HostingProviderDetail>();
