IQueryable with Entity Framework - order， where， skip and ta

Question

我正在使用实体框架(代码优先(，如下所示：

IQueryable<StammdatenEntityModel> query = dbSet;
query.OrderByDescending(s => s.CreateDateTime);
query.Where(s => s.Deleted == false);
if(!String.IsNullOrEmpty(keyword))
{
query.Where(s => s.SerialNumber.Contains(keyword)); //simplified for SO
}
query.Skip(skip);
query.Take(take);

然而OrderByDescending、Where、Skip和Take没有任何影响。

Answer 1

您没有使用查询结果

IQueryable<StammdatenEntityModel> query = dbSet;
query = query.OrderByDescending(s => s.CreateDateTime);
query = query.Where(s => s.Deleted == false);
if(!String.IsNullOrEmpty(keyword))
{
query = query.Where(s => s.SerialNumber.Contains(keyword)); //simplified for SO
}
query = query.Skip(skip);
query = query.Take(take);
