反射-动态加载和使用类型
1
反射提供语言编译器(如 Microsoft Visual Basic 2005 和 JScript)用于实现隐式后期绑定的基础结构。绑定是查找与唯一指定的类型相对应的声明(即实现)的过程。如果此过程是在运行时而不是在编译时发生,则称其为“后期绑定”。利用 Visual Basic 2005,可以在代码中使用隐式后期绑定;Visual Basic 编译器会调用一个帮助器方法,该方法使用反射来获取对象类型。传递给帮助器方法的参数有助于在运行时调用正确的方法。这些参数包括:对其调用方法的实例(对象),被调用方法的名称(字符串),以及传递给被调用方法的参数(对象数组)。

3
在下面的示例中,Visual Basic 编译器使用反射隐式地对其类型在编译时未知的对象调用方法。HelloWorld 类具有一个 PrintHello 方法,它输出与传递给 PrintHello 方法的某些文本串联的“Hello World”。在此示例中调用的 PrintHello 方法实际上是 Type..::.InvokeMember;Visual Basic 代码允许按照对象 (helloObj) 的类型在编译时已知(早期绑定)而不是在运行时已知(后期绑定)的方式来调用 PrintHello 方法。

Imports System
7
Module Hello
8
Sub Main()
9
' Sets up the variable.
10
Dim helloObj As Object
11
' Creates the object.
12
helloObj = new HelloWorld()
13
' Invokes the print method as if it was early bound
14
' even though it is really late bound.
15
helloObj.PrintHello("Visual Basic Late Bound")
16
End Sub
17
End Module

自定义绑定
21
除了由编译器隐式地用来进行后期绑定之外,反射还可以在代码中显式地用来完成后期绑定。
22![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
23
公共语言运行库支持多种编程语言,但这些语言的绑定规则各不相同。在早期绑定的情况下,代码生成器可以完全控制此绑定。但是,当通过反射进行后期绑定时,必须用自定义绑定来控制绑定。Binder 类提供了对成员选择和调用的自定义控制。
24![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
25
利用自定义绑定,您可以在运行时加载程序集,获取有关该程序集中类型的信息,然后对该类型调用方法或访问该类型的字段或属性。如果您在编译时(例如当对象类型依赖于用户输入时)不知道对象的类型,就可以使用这种方法。
26![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
27
下面的示例说明不提供参数类型转换的简单的自定义联编程序。Simple_Type.dll 的代码位于示例主体之前。确保生成 Simple_Type.dll,然后在生成时在项目中包括对它的引用。

InvokeMember 和 CreateInstance

使用 Type..::.InvokeMember 可调用类型的成员。各个类(如 System.Activator 和 System.Reflection.Assembly)的 CreateInstance 方法是 InvokeMember 的特殊形式,它们可新建特定类型的实例。Binder 类用于在这些方法中进行重载决策和参数强制。
413![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
414
下面的示例显示参数强制(类型转换)和成员选择的三种可能的组合。在第 1 种情况中,不需要任何参数强制或成员选择。在第 2 种情况中,只需要成员选择。在第 3 种情况中,只需要参数强制。

460
当多个成员具有相同的名称时,将需要重载决策。Binder..::.BindToMethod 和 Binder..::.BindToField 方法用于解析与单个成员的绑定。Binder.BindToMethod 还通过 get 和 set 属性访问器提供了属性解析。
461![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
462
BindToMethod 返回要调用的 MethodBase;如果无法进行这种调用,则返回 null 引用(在 Visual Basic 中为 Nothing)。虽然 MethodBase 返回值通常是 match 参数中所包含的值之一,但它并不必如此。
463![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
464
当存在 ByRef 参数时,调用方可能需要取回这些参数。因此,如果 BindToMethod 已经操作参数数组,Binder 会允许客户端将参数数组映射回它的初始形式。为了实现这一目的,必须向调用方保证参数的顺序不会改变。当按名称传递参数时,Binder 将重新排列参数数组,这就是调用方所见的参数。有关更多信息,请参见 Binder..::.ReorderArgumentArray。
465![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
466
可用成员集包括在类型和任何基类型中定义的成员。如果指定 BindingFlags.NonPublic,将返回该成员集中具有任何可访问性的成员。如果未指定 BindingFlags.NonPublic,联编程序就必须强制可访问性规则。当指定 Public 或 NonPublic 绑定标志时,还必须指定 Instance 或 Static 绑定标志,否则不会返回任何成员。
467![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
468
如果只有一个成员具有给定名称,则不必进行回调,而在该方法上进行绑定。代码示例的第 1 种情况说明了这一点:只有一个 PrintBob 方法可用,因此不需要进行回调。
469![](https://www.cnblogs.com/Images/OutliningIndicators/None.gif)
470
如果可用集中有多个成员,所有这些方法都将传递给 BindToMethod,它将选择正确的方法并将其返回。在代码示例的第 2 种情况下,有两个名为 PrintValue 的方法。对 BindToMethod 的调用将选择正确的方法。

ChangeType 执行参数强制转换(类型转换),以便将实参转换为选定方法的形参的类型。即使类型完全匹配,也会为每个参数调用 ChangeType。

474
在代码示例的第 3 种情况下,将类型为 String 值为“5.5”的实参传递给了具有类型为 Double 的形参的方法。要使调用成功,必须将字符串值“5.5”转换为 double 值。ChangeType 会执行此转换。

ChangeType 仅执行无损或扩大强制,如下表所示。

Type 类具有 Get 方法,这些方法使用 Binder 类型的参数来解析对特定成员的引用。Type..::.GetConstructor、Type..::.GetMethod 和 Type..::.GetProperty 通过为当前类型的特定成员提供签名信息来搜索该成员。对 Binder..::.SelectMethod 和 Binder..::.SelectProperty 进行回调以选择相应方法的给定签名信息。
