DBContext Filtering
本文关键字:Filtering DBContext | 更新日期: 2023-09-27 18:12:23
if (NavigationContext.QueryString.TryGetValue("selectedItem", out selectedArea))
{
using (dbContext c = new dbContext(dbContext.ConnectionString))
{
c.CreateIfNotExists();
c.LogDebug = true;
MainLongListSelector.ItemsSource = c.details.ToList();
}
}
我想过滤dbcontext中的内容,我该怎么做?谁来帮帮我
try in this way
MainLongListSelector.ItemsSource = c.details.Where(elem=> elem.Property==5).ToList();// returns elements with Property=5
我假设你的details
有一个名称为Property
的属性,但你可以使用你的字段,例如.Where(elem=> elem.Name=='Peeter' && elem.Age > 30) //takes elements with Age > 30 and Name=Peter
