一些思考的时间

简介
本文将重点。NET Framework中的反射API。反思文档通常包括属性和编写动态代码，但我会避免后者，并试图解释一些比较重要的方面使用反射，即使它可能不会出现有任何书面现实世界的应用价值。相反，它和一个人得到精通它，将能够使用反射写开发工具，甚至计划，减少堆消费。对于初学者的重要缘故，某些路段会一步虽然一些源代码，以获得一个C＃语法的掌握，但在我有限的知识）的文章（大概接近中间。反射是经常被用来确定哪些类型的程序集的定义。 Framework类库提供了许多方法来获取这些信息，但最常用的方法是大会GetExportedTypes。以下只是一些示例源代码，加载程序集和显示中定义的所有公开导出的类型名称。一些基本的解释后，输出会出现在下面的部分。检查此代码，然后我们将在大会类的方法，属性和静态方法。 大会类的静态方法GetAssemblyGetCallingAssemblyGetEntryAssemblyGetExecutingAssembly负载的LoadFile的LoadFromReflectionOnlyLoadReflectionOnlyLoadFrom
正如你可以看到，GetExportedTypes方法也不是一成不变的的。检查大会类的属性:入口点真实姓名GlobalAssemblyCache地点ReflectionOnly
在这一点上，它是重要的检查语法。研究这个程序:{C}
下面是输出:

c:\Windows\Microsoft.NET\Framework\v4.0.30319>getmod

System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

From GAC? True

   Mod: System.dll

From GAC? False

Path:     c:\Windows\Microsoft.NET\Framework\v4.0.30319\GetMod.exe

Version:  v4.0.30319

   Mod: GetMod.exe

代码首先声明了一个字符串:
string path = @"C:\windows\Microsoft.net\Framework\v2.0.50727\System.dll";

引号的字符串存储在分配给String对象的值？？代码>路径？？因此认为在左引号中（其中包含要加载的程序集）的目录路径的参考。下一行代码实例化类大会。这是等于向大会类？？静态方法的LoadFile。请注意，该方法具有上述路径（其中存储的字符串值）作为参数传递的值。还要注意以下代码>大会现在存储该程序集的路径，因为它现在已经加载？？？？:
Assembly a = Assembly.LoadFile(path);

在这一点上，我们写了一个静态方法来显示当前加载的程序集的信息。目前正在执行中，我们实例大会类的另一个实例。静态方法ShowAssemblyInfo做什么顾名思义。重要的是对于初学者要注意原始值的代码>一个是作为参数传递的是点语法写入显示属性的字符串路径的参考作用:？？？（一个地点，a.GlobalAssemblyCache，a.FullName，等等）下面是一些大会类的方法，AREN，AOT静态？？:的CreateInstanceGetCustomAttributesGetExportedTypesGetModuleGetModulesGetTypes
在说，让AOS看看原始的源代码的输出。对于为了简单起见，请注意，这些都是（近一半）市民的出口类型:

该对象是什么类型？
或者，什么是类型对象呢？正如我们都知道，。NET中的所有对象派生自System.Object。在这根命名空间中定义的方法的GetType。请注意，前面的代码迭代的System.Type对象数组。的System.Type类型是你的出发点做类型和对象操作。的System.Type是一个抽象基的类型从System.Reflection.MemberInfo派生（因为类型可以是另一种类型的成员）。整箱提供了几种类型的System.Type从派生:System.RuntimeType， System.ReflectionOnlyType，System.Reflection.TypeDelegator，并在System.Reflection中定义的一些类型。发出的命名空间（EnumBuilder，GenericTypeParameterBuilder，并TypeBuilder）。 Object类支持的方法GetType返回一个类型的对象，是指一个对象的实际类型。例如，让AOS创建一个动物类，然后创建两个类，动物类派生:
using System;

public class Animal

   {

   }

public class Dog : Animal

   {

   }

public class Cat : Animal

   {

   }

class App {

static void Main() {

Animal aAnim = new Animal();

Animal aDog = new Dog();

Animal aCat = new Cat();

Console.WriteLine("Typename for aAnim is {0}", aAnim.GetType().Name);

Console.WriteLine("Typename for aDog is {0}", aDog.GetType().Name);

Console.WriteLine("Typename for aCat is  {0}", aCat.GetType().Name);

 }

}

输出与预期。请注意使用的代码> typeof关键字？？？:
Typename for aAnim is Animal

Typename for aDog   is Dog

Typename for aCat   is  Cat

构造泛型类型的实例，首先获得一个开放式的参考，然后呼叫类型，AOS公共实例调用MakeGenericType方法，传递要使用类型参数类型的数组。然后，返回的类型对象，并传递到上面列出的各种方法之一。下面是一个例子:
using System; 

using System.Reflection; 

using System.Collections.Generic; 

using System.Linq; 

internal sealed class Dictionary<tkey, /> { } 

public static class Program { 

public static void Main() 

{ 

Type openType = typeof(Dictionary<,>); 

Type closedType = openType.MakeGenericType(typeof(String), 

	typeof(Int32)); Object o = Activator.CreateInstance(closedType); 

Console.WriteLine(o.GetType()); 

} 

}

当您编译此代码，你应该得到以下结果:
Dictionary`2[System.String,System.Int32]
使用反射来发现一个类型的成员
据微软的技术文档，能够发现和调用类型的成员通常用于创建开发工具和实用程序，通过一定的编程模式，或使用某些成员大会，分析。工具/实用工具，做到这一点的例子是ILDASM.EXE，FxCopCmd.exe，和Visual Studio中的Windows窗体和网页设计师。
字段，构造，方法，属性，事件，和嵌套类型都可以被定义为在一个类型的成员。整箱包含名为System.Reflection.MemberInfo类型。这个类是一个抽象的基类，它封装了所有类型的成员的共同属性的一堆。从MemberInfo的派生一堆类，每类封装了相关的一些特定类型的成员更多的属性。以下是这些类型的层次结构列表:
System.Object

System.Reflection.MemberInfo

System.Type

System.Reflection.FieldInfo

System.Reflection.MethodBase

System.Reflection.ContructorInfo

System.Reflection.MethodInfo

System.Reflection.PropertyInfo

System.Reflection.EventInfo

对于每个类型的，GetMembers方法被调用，并返回的MemberInfo派生的对象的数组，每个对象是指一个单一的类型内定义的成员。 ，BF的BindingFlags变量传递到GetMembers方法，告诉该方法返回成员。然后，为每个成员，其种类（字段，构造函数，方法，属性，等）和它的字符串值（调用toString得到）所示。不久将讨论主题的BindingFlags。研究这样的代码:
using System;

using System.Reflection;

public static class Program {

public static void Main() {

// Loop through all assemblies loaded in this AppDomain

Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();

foreach (Assembly a in assemblies) {

WriteLine(0, "Assembly: {0}", a);

// Find Types in the assembly

foreach (Type t in a.GetExportedTypes()) {

WriteLine(1, "Type: {0}", t);

// Discover the type's members

const BindingFlags bf = BindingFlags.DeclaredOnly |

BindingFlags.NonPublic | BindingFlags.Public |

BindingFlags.Instance | BindingFlags.Static;

foreach (MemberInfo mi in t.GetMembers(bf)) {

String typeName = String.Empty;

if (mi is Type) typeName = "(Nested) Type";

else if (mi is FieldInfo) typeName = "FieldInfo";

else if (mi is MethodInfo) typeName = "MethodInfo";

else if (mi is ConstructorInfo) typeName = "ConstructoInfo";

else if (mi is PropertyInfo) typeName = "PropertyInfo";

else if (mi is EventInfo) typeName = "EventInfo";

WriteLine(2, "{0}: {1}", typeName, mi);

    }

  }

 }

}

 private static void WriteLine(Int32 indent, String format, params Object[] args) {

Console.WriteLine(new String(' ', 3 * indent) + format, args);

  }

}

编译后的代码运行时，大量的信息输出。这里是一个小样本的输出，并尝试建立连接的层次结构列表。

使用的的BindingFlags
BindingFlags枚举是用来控制一个类型的成员是如何检索使用的GetMembers方法，以及每个成员的类型的具体成员。更重要的一点，选举产生的议员的BindingFlags筛选种。您查询的类型，调用类型，AOS GetMembers，GetNestedTypes，GetFields，GetConstructors，GetMethods，GetProperties，或GetEvents方法AOS成员。当您调用这些方法中的任何一种，您可以通过在一个System.Reflection.BindingFlags枚举类型的一个实例。枚举类型的标识设置标志位，AOD一起帮助您过滤，这些方法返回的成员。尽管事实是，我们使用的BindingFlags是我们最后一个例子，这里是源代码，充分体现了其直目的:
using System;

using System.Reflection;

public class Program

 {

    public static void Main(string[]  args)

    {

      string path = @"C:\Windows\Microsoft.NET\Framework\v2.0.50727\" +

      "System.ServiceProcess.dll";



       // using BindingFlags to only get the declared

       // and instance members



       BindingFlags flags =

       BindingFlags.DeclaredOnly |

       BindingFlags.Public |

       BindingFlags.Instance;



       Assembly a = Assembly.LoadFrom(path);

       Console.WriteLine(a.FullName);



       Type[] types = a.GetTypes();



       foreach ( Type t in types )

       {

         Console.WriteLine("  Type:  {0}", t.Name);

         MemberInfo[] m = t.GetMembers(flags);



       foreach (MemberInfo member in m)

        {

           Console.WriteLine("  {0}: {1}", member.MemberType, member.Name);

        }

       }



       Console.Read();

     }

  }

当我们运行编译后的代码，我们将看到（像往常一样，有大量信息），净使用API​​返回信息类型thatnbsp;接受的BindingFlags标志风格的枚举值来约束搜索那些持有的某些属性的抽象:

最后，记得C＃编译器发出元数据和IL代码。元数据存储在一堆表。当你建立一个程序集或模块，您正在使用的编译器将创建一个类型定义表，字段定义表，方法定义表，等等。 System.Reflection命名空间中包含了几种类型，让您编写代码，以反映（或解析）这些元数据表。实际上，这个命名空间中的类型提供了程序集或模块中元数据的对象模型。使用这些类型的对象模型，您可以轻松地枚举类型定义元数据表中的所有类型。然后为每个类型，可以获取其基本类型，它实现的接口和类型相关的标志。在System.Reflection命名空间中的其他类型允许你查询的类型的字段，方法，属性，并通过分析相应的元数据表的事件。如果你要编写一个组件，你可以利用，然后转储大会和研究它的信息。用来做完全是一个宝贵的工具。NET的反射。参考文献专业。NET Framework 2.0中，乔达菲的书面历史8月27日，2010年:战后初期

新手没问题 - 大家都开始某处（！，大多是，我们没有任何挑战你尝试什么附近开始）

首先要注意的是，在MSDN页面的示例代码的C / C，而不是C＃。这是一个很大的区别，示例代码将不会编译在C＃类库。所以，你要么创建一个DLL使用C / C，或转化为等价的C＃代码的C代码。

这两种方法前，你需要创建在其中粘贴示例代码从MSDN页面的非托管（三）DLL。希望样本是完整和正确的，而且会产生明显的效果，可以借鉴。要调用到这样的一个C＃控制台应用程序的DLL，你需要使用P / Invoke来参考到DLL的入口点（S），你会从C＃中使用。

跳深结和创建从样品。NET / C＃的DLL，您也将使用P / Invoke的，但这个时候，引用调用SetWindowsHookEx和任何其他的Windows方法将被调用。您需要了解
StructLayout属性，IntPtr和无疑其他互操作所需的晦涩难懂的细节。

要明白为什么页面说，从您的控制台应用程序使用一个单独的DLL，您需要了解原生DLL的性质（这是从大异其趣。NET程序集编译成DLL），DLL和EXE如何不同。 。NET程序员，这是有点低层次的东西，但值得理解。我没有安装Windows挂钩自己，所以在这里我只是猜测，但EXE和DLL的"看"到Windows（不是猜测）不同，所以调用SetWindowsHookEx方法可能只是不工作，如果它是从一个EXE调用（
这是猜测）。
在安装一个窗钩，你告诉Windows的"这里的一些有效的代码（DLL的），这里是哪里来跳时，钩子是发射" - 并从这个角度的Windows只有了解本土的东西（和不知道的所有东西。NET）。当Windows要调用您的钩子，它需要确定DLL是否正确初始化（你可能有全局（静态）变量和其他事情之前，安全地运行在DLL的方法，需要初始化 - 初始化初始化一个EXE，DLL是非常不同。

我们希望，所有的一些有意义的。
