我认为您不能将条件放入较大的查询中，但是您可以将其分成另一个C#语句，如下所示:>

I don't think you can put a condition into the larger query, but what you could do is separate it into another C# statement, like this:

// 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>();
