The document summarizes key aspects of applied media aesthetics in two commercials and a movie scene from "Natural Born Killers". It discusses how lighting, sound, motion, angles, and context work together to interpret events for audiences in the Old Spice commercial. Constant motion from actors and cameras, tilted angles and zooms were used to create energy in the "Natural Born Killers" scene.
Japanese Animation, also known as anime, originates from Japan and can apply to all genres of film. It is a stylized form of animation characterized by features such as bigger eyes and smaller noses. Anime goes through similar production processes as other films, involving voice actors, music, and special effects. Some influential early anime works include Osamu Tezuka's Astro Boy from the 1960s. Anime has a large audience in Japan and worldwide recognition, being distributed via television, video, theaters, and the internet. Examples of popular anime films discussed in the document are Grave of the Fireflies, Akira, and My Neighbor Totoro.

3. 这个概念很简单,其简化了我们在.NET 的时候手写一堆私有成员+属性的编程方式,我们只需要使用如下
方式声明一个属性,编译器会自动生成所需的成员变量。
public class Customer
{
public int Id { get; set; }
public string Name { get; set; }
}
在我使用 LINQ 完成的项目中,使我了解到自动属性方便的一个用途如下:
在使用 LINQ 获取数据的过程中,我们常常需要使用 select new 语句查询出一个对象(往往是 IEnumer
able 类型的)用于数据绑定。在一般情况下如果是直接绑定(如直接将查询结果赋给一个 Gridview 控件的
DataSource 属性)我们可以直接 select new 来返回一个匿名类的对象。如果我们还需要对这个集合对象
进行进一步操作,我们将必须使用 select new classname 这样的语言返回一个类的对象,大部分情况下
这个类只作为实体的一个结构而不需要完成一些操作操作,这时候使用自动属性来完成这个类将是非常简
洁高效的。
隐式类型
这个名称可能对你很陌生,但是 var 这个关键字应该都用过,在 C#中使用 var 声明一个对象时,编译器会
自动根据其赋值语句推断这个局部变量的类型。赋值以后,这个变量的类型也就确定而不可以再进行更改。
另外 var 关键字也用于匿名类的声明。
应用场合:var 主要用途是表示一个 LINQ 查询的结果。这个结果可能是 ObjectQuery<>或 IQueryable<
>类型的对象,也可能是一个简单的实体类型的对象。这时使用 var 声明这个对象可以节省很多代码书写上
的时间。
对象初始化器与集合初始化器
在.NET2.0 中构造一个对象的方法一是提供一个重载的构造函数,
二是用默认的构造函数生成一个对象,
然后对其属性进行赋值。在.NET3.5/C#3.0 中我们有一种更好的方式来进行对象的初始化。那就是使用对
象初始化器。这个特性也是匿名类的一个基础,所以放在匿名类之前介绍。
还是那就话,好的代码强于注释,下面用几个代码段说明初始化器:
(代码出自:李永京的博客 http://lyj.cnblogs.com)
基本用法:
User user = new User { Id = 1, Name = "YJingLee", Age = 22 };
嵌套使用:
User user = new User
{
4. Id = 1,
Name = "YJingLee",
Age = 22,
Address = new Address
{
City = "NanJing",
Zip = 21000
}
};
类似于对象初始化器初始化一个对象,集合初始化器初始化一个集合,一句话,有了它你就不用在将元
素通过 Add 逐个添加了。仍然给出代码示例:
基本使用:
List<int> num = new List<int> { 0, 1, 2, 6, 7, 8, 9 };
结合对象初始化器,我们可以写出如下简洁的代码:
List<User> user = new List<User>{
new User{Id=1,Name="YJingLee",Age=22},
new User{Id=2,Name="XieQing",Age=25},
};
应用场合:
还是前文提到的 select new classname 语法,后面可以直接接一个初始化器来将查询结果返回到这个
对象。
匿名类
有了前文初始化器的介绍,
匿名类就很简单了。
我们可以使用 new { object initializer }或 new[]{ object, …}
来初始化一个匿名类或不确定类型的数组。匿名类的对象需要使用 var 关键字声明。示例代码:
var p1 = new { Id = 1, Name = "YJingLee", Age = 22 };
应用场合:
还是同上面的例子提到的当直接使用 select new { object initializer }这样的语法就是将一个 LINQ 查询的
结果返回到一个匿名类中。
扩展方法
26. {
cn.Open();
EntityCommand cmd = cn.CreateCommand();
cmd.CommandText = @"SELECT VALUE c FROM Entities.Customers AS c WHERE
c.Address.City = @city";
cmd.Parameters.AddWithValue("city", city);
DbDataReader rdr = cmd.ExecuteReader(CommandBehavior.SequentialAccess);
while (rdr.Read())
Console.WriteLine(rdr["CompanyName"].ToString());
rdr.Close();
}
· ObjectService+EntitySQL
在有 EntityClient+EntitySQL 这种使用方式下,使用 ObjectService+EntitySQL 的方式是多此一举,不会得
到任何编辑时或运行时的好处。在 ObjectContext 下使用 EntitySQL 的真正作用是将其与 LINQ to Entity
结合使用。具体可见下文所示。
示例代码:
string city = "London";
using (Entities entities = new Entities())
{
ObjectQuery<Customers> query = entities.CreateQuery<Customers>(
"SELECT VALUE c FROM Customers AS c WHERE c.Address.City = @city",
new ObjectParameter("city", city)
);
foreach (Customers c in query)
Console.WriteLine(c.CompanyName);
}
· ObjectContext+LINQ( to Entity)
27. 方式一:
string city = "London";
using (Entities entities = new Entities())
{
var query = from c in entities.Customers
where c.Address.City == city
select c;
foreach (Customers c in query)
Console.WriteLine(c.CompanyName);
}
方式二:
string city = "London";
using (Entities entities = new Entities())
{
var query = entities.Customers.Where(r => r.Address.City == city);
foreach (Customers c in query)
Console.WriteLine(c.CompanyName);
}
这两段示例代码中的 entities.Customer 的写法隐式调用了 2 中示例的 ObjectQuery<Customers>来进行查
询(关于此可以参见 EDM 的设计器文件xxx.designer.cs)。在方式二中的 Where 方法传入的是一个 La
mbda 表达式,你也可以传入一条 EntitySQL 语句做参数来将 LINQ 与 EntitySQL 结合使用。如下代码演示
其使用:
string city = "London";
using (Entities entities = new Entities())
{
var query = entities.Customers.Where("r.Address.City = '"+city+"'");
foreach (Customers c in query)
Console.WriteLine(c.CompanyName);
}
28. 使用技巧及需要注意的问题
这也是上文提到的在 ObjectContext 下使用 EntitySQL 的一个主要作用,上面的例子比较简单可能看不到
这样使用的优势,但是如下两种情况下使用 EntitySQL 可能是最好的选择。
· 动态构建查询条件
当查询条件的个数固定时,我们也可以采用罗列多个 Where 扩展方法的形式,如下:
ObjectQuery.Where(LambdaExpression1) .Where(LambdaExpression2)…
· 但是当这个条件的存在与否需要在运行时判断时,我们只能通过组合字符串来得到这个条件,我
们可以将条件组合为 EntitySQL 并传递给 Where()方法。
· 数据库模糊查询
下面代码演示使用 EntitySQL 的 like 完成模糊查询:
context.Customer.Where("it.CustomerID LIKE @CustomerID", new
System.Data.Objects.ObjectParameter("CustomerID","%V%"));
这个并不是只能使用 EntitySQL 来实现,LINQ to Entity 也可以很容易完成。如下代码:
context.Customer.Where(r => r.CustomerID.Contains("V"));
同理,"V%"、"%V"可以分别使用 StartsWith()与 EndsWith()函数实现。
使用 LINQ to Entity 需要注意的一个方面是,
在完成查询得到需要的结果后使用 ToList 或 ToArray 方法
将结果转变为内存中的对象,然后使用 LINQ to Objects 来处理,否则处在 Entity Framework 的联机模式
下对性能有很大的影响。
几种方法的性能分析及使用选择
首先用下图来说明一个执行过程。
图中所示表达的意思已经非常清楚,稍加解释的是,无论是通过 EntityClient 直接提供给 Entity Client
Data Provider 的 Entity SQL 还是通过 ObjectService 传递的 Entity SQL(或是 LINQ to Entity),都在
Entity Client Data Provider 中被解释为相应的 Command Tree,并进一步解释为对应数据库的 SQL。这
32. 实体相关的一个集合。我们只需在访问关系中实体之前调用其 Load 即可,当然提前判断该实体是否
已经加载是一种比较好的实践。如下代码所示
using (Entities entities = new Entities())
{
var query = (from o in entities.Orders
where o.Customers.CustomerID == "ALFKI"
select o);
foreach (Orders order in query)
{
if (!order.CustomersReference.IsLoaded)
order.CustomersReference.Load();
Console.WriteLine(order.OrderID + " " +
order.Customers.CompanyName);
}
}
· 预先加载
先看代码示例
using (Entities entities = new Entities())
{
var query = (from o in entities.Orders.Include("Customers")
where o.ShipCountry == "USA"
select o);
foreach (Orders order in query)
Console.WriteLine(order.OrderID + " " +
order.Customers.CompanyName);
}
查询中针对 Orders 实体调用的 Include 方法接受了一个参数,该参数在本示例中将要求查询不仅要检索
Orders,而且还要检索相关的 Customers。这将生成单个 SQL 语句,它会加载满足 LINQ 查询条件的
所有 Order 和 Customer。
