Type 关键字解读

概述

System.Type 类对于反射起着核心的作用。但它是一个抽象的基类，Type有与每种数据类型对应的派生类，我们使用这个派生类的对象的方法、字段、属性来查找有关该类型的所有信息。

Type Assembly的用途：
    （1）使用Assembly定义和加载程序集，加载在程序集清单中列出模块，以及从此程序集中查找类型并创建该类型的实例。
    （2）使用Module了解包含模块的程序集以及模块中的类等，还可以获取在模块上定义的所有全局方法或其他特定的非全局方法。
    （3）使用ConstructorInfo了解构造函数的名称、参数、访问修饰符（如pulic 或private）和实现详细信息（如abstract或virtual）等。
    （4）使用MethodInfo了解方法的名称、返回类型、参数、访问修饰符（如pulic 或private）和实现详细信息（如abstract或virtual）等。
    （5）使用FiedInfo了解字段的名称、访问修饰符（如public或private）和实现详细信息（如static）等，并获取或设置字段值。
    （6）使用EventInfo了解事件的名称、事件处理程序数据类型、自定义属性、声明类型和反射类型等，添加或移除事件处理程序。
    （7）使用PropertyInfo了解属性的名称、数据类型、声明类型、反射类型和只读或可写状态等，获取或设置属性值。
    （8）使用ParameterInfo了解参数的名称、数据类型、是输入参数还是输出参数，以及参数在方法签名中的位置等。

  System.Type 类－－通过这个类可以访问任何给定数据类型的信息。

   获取给定类型的Type引用有3种常用方式：
●使用 C# typeof 运算符。

?

1	Type t = typeof(string);

    ●使用对象GetType()方法。

?

1 2	string s = "grayworm";        Type t = s.GetType();

    ●还可以调用Type类的静态方法GetType()。
 

?

1	Type t = Type.GetType("System.String");

 

Type类的属性：
        Name 数据类型名
        FullName 数据类型的完全限定名(包括命名空间名)
        Namespace 定义数据类型的命名空间名
        IsAbstract 指示该类型是否是抽象类型
        IsArray   指示该类型是否是数组
        IsClass   指示该类型是否是类
        IsEnum   指示该类型是否是枚举
        IsInterface    指示该类型是否是接口
        IsPublic 指示该类型是否是公有的
        IsSealed 指示该类型是否是密封类
        IsValueType 指示该类型是否是值类型
Type类的方法：
        GetConstructor(), GetConstructors()：返回ConstructorInfo类型，用于取得该类的构造函数的信息
        GetEvent(), GetEvents()：返回EventInfo类型，用于取得该类的事件的信息
        GetField(), GetFields()：返回FieldInfo类型，用于取得该类的字段（成员变量）的信息
        GetInterface(), GetInterfaces()：返回InterfaceInfo类型，用于取得该类实现的接口的信息
        GetMember(), GetMembers()：返回MemberInfo类型，用于取得该类的所有成员的信息
        GetMethod(), GetMethods()：返回MethodInfo类型，用于取得该类的方法的信息
        GetProperty(), GetProperties()：返回PropertyInfo类型，用于取得该类的属性的信息
    可以调用这些成员，其方式是调用Type的InvokeMember()方法，或者调用MethodInfo, PropertyInfo和其他类的Invoke()方法。

BindingFlags 枚举

成员名称	说明
Default	没有绑定标志。
IgnoreCase	绑定时不应考虑成员名的大小写。
DeclaredOnly	只应考虑在所提供类型的层次结构级别上声明的成员。 不考虑继承成员。
Instance	实例成员应包含在搜索中。
Static	搜索中应包含静态成员。
Public	搜索中应包含公共成员。
NonPublic	搜索中应包含非公共成员。
FlattenHierarchy	应返回层次结构上的公共静态成员和受保护的静态成员。 不返回继承类中的私有静态成员。 静态成员包括字段、方法、事件和属性。 不返回嵌套类型。
InvokeMethod	要调用一个方法。 它不能是构造函数或类型初始值设定项。
CreateInstance	反射应当创建指定类型的实例。 此标志调用与给定参数匹配的构造函数。 忽略提供的成员名。 如果未指定查找类型，将应用 (Instance |Public)。 调用类型初始值设定项是不可能的。
GetField	应返回指定字段的值。
SetField	应设置指定字段的值。
GetProperty	应返回指定属性的值。
SetProperty	应设置指定属性的值。 对于 COM 属性，指定此绑定标志与指定 PutDispProperty 和 PutRefDispProperty 是等效的。
PutDispProperty	应调用 COM 对象的 PROPPUT 成员。 PROPPUT 指定使用值的属性设置函数。 如果属性同时具有 PROPPUT 和 PROPPUTREF，而且需要区分调用哪一个，请使用 PutDispProperty。
PutRefDispProperty	应调用 COM 对象的 PROPPUTREF 成员。 PROPPUTREF 指定使用引用而不是值的属性设置函数。 如果属性同时具有 PROPPUT 和 PROPPUTREF，而且需要区分调用哪一个，请使用 PutRefDispProperty。
ExactBinding	提供的参数的类型必须与对应形参的类型完全匹配。 如果调用方提供一个非空 Binder 对象，则“反射”将引发异常，因为这意味着调用方正在提供的 BindToXXX 实现将选取适当的方法。 默认联编程序忽略此标志，而自定义联编程序可以实现此标志的语义。
SuppressChangeType	未实现。
OptionalParamBinding	应返回其参数计数与提供的参数的数目匹配的成员集。 此绑定标志用于所带参数具有默认值的方法和带变量参数 (varargs) 的方法。 此标志应只与 Type.InvokeMember 方法一起使用。 具有默认值的参数仅用在省略尾部参数的调用中。 它们必须是最后的参数。
IgnoreReturn	在 COM 互操作中用于指定可以忽略成员的返回值。

一些总结

以DICOMParser dicomParser; 为例

1. 通过typeof(DICOMParser ) 或者 dicomParser.GetType() 获取类型信息, 推荐使用typef() 可以避免空引用,而且有的时候不需要构造一个DICOMParser 的实例,

typeof(DICOMParser )的性能一点都不差,不要把它和反射混为一谈,

2.对于Type.IsPrimitive来说  很多常见的类型不是原生类型

例如 String DateTime decimal 都不是原生类型

按照MSDN的说明  原生类型只包括:http://msdn.microsoft.com/en-us/magazine/bb984984.aspx

3.对于数组来说 , typeof(DICOMParser [])

可以使用Type.IsArray来判断是否数组

可以使用Type.GetElementType 获取元素的类型 , 在这里等价于typeof(DICOMParser )

数组实际上继承于System.Array, 但是数组也实现IEnumerable<T>的接口 (这会让数组和List<T>等常见类型可以按照同样的方式处理)

3.泛型来说 ,Typeof(List<DICOMParser>)

可以使用Type.IsGenericType 来判断是否是泛型类型

可以使用Type.GetGenericTypeDefinition()来获取泛型类型(开放类型) ,在这里等价于 typeof(List<>)

使用Type.GetGenericArguments()获取泛型参数集合 在这里,集合中的第一个元素等价于typeof(DICOMParser)

对于Dictionary<string,DICOMParser> 这样的字典定义来说, Type.GetGenericArugment()会返回两个类型,分别是typeof(string)和typeof(DICOMParser)  他的开放类型是typeof(Dictionary<,>)

4.可以调用Type.GetInterfaces() 然后判断某个类型是否继承与某个接口

例如数组和List<T>都继承与IEnumerable<T> 这样就可以用统一的方式处理

5.可空值类型 例如 int? 本质上也是泛型 他的开放类型是typeof(System.Nullable<>)这里的开放类型指的是类型不完全, 需要增加参数(一般是泛型参数) 才能构成一个真正的类型, 例如List<> , 增加泛型参数string 变为List<string>

开放类型还不是一个完整的类型 不能直接构造出一个实例封闭类型已经是一个完整的类型了 可以new ..
