还是习惯先撸一段SQL * FROM User_Pic P AND P.Guid = R.UserPicGuid ORDER BY PicSize DESC 然后发现Linq中的join不能多条件... 结果找到解决方案如下 ; var pic = (from p in db.User_Pic join r in db.R_User_Pic on new { _guid = p.Guid, _id = ID } equals new { _guid = r.UserPicGuid, _id =
public ActionResult Edit(int id) { using (DataContext db = new DataContext(ConfigurationManager.ConnectionStrings["sqlConnection"].ConnectionString)) { IQueryable<ClassInformation> result = from c in db.GetTable<TClass>() join t in d
代码如下: private void FrmMain_Load(object sender, EventArgs e) { var list1 = Supplier.GetSuppliers(); var list2 = Product.GetProducts(); var listEnd = from a in list1 join b in list2 on new { id = a.SupplierID, name = a.Name } equals new { id = b.Suppli
使用VBA对指定的单元格赋值并填充颜色 ====================================================== 代码区域 ====================================================== Sub row应用() For Each rw In Rows("1:13") = Then rw.Interior.ColorIndex = rw.Value = End If Next End Sub 效果如下图:
原文:使用ArcGIS API for Silverlight 进行复合多条件空间查询 这两天帮网上认识的一个兄弟做了一个查询的示例,多多少少总结一下,在此和大家分享. 为什么说是复合多条件呢?因为进行空间查询有时候我们查询的条件会很复杂,比如要求某一要素的某一属性大于多少,且小于多少,且又不等于多少等等.而在官网给出的例子中并没有关于复合查询的说明.不过查看API后,你会发现一句很重要的话: A where clause for the query. Any legal SQL where c
