範例

下列範例顯示 Type的幾個代表性功能。The following example shows a few representative features of Type. typeof C#運算子(Visual Basic 中的GetType 運算子)是用來取得代表 StringType 物件。The C# typeof operator (GetType operator in Visual Basic) is used to get a Type object representing String. 從這個 Type 物件中,GetMethod 方法是用來取得 MethodInfo,代表採用起始位置和長度的 String.Substring 多載。From this Type object, the GetMethod method is used to get a MethodInfo representing the String.Substring overload that takes a starting location and a length.

為了識別多載簽章,此程式碼範例會建立一個暫存陣列,其中包含兩個代表 intInteger 在 Visual Basic 中)的 Type 物件。To identify the overload signature, the code example creates a temporary array containing two Type objects representing int (Integer in Visual Basic).

注意

若要精確,陣列會包含兩個 Type 的實例參考,代表目前應用程式域中 intTo be precise, the array contains two references to the instance of Type that represents int in the current application domain. 針對任何類型,每個應用程式域只有一個 Type 實例。For any type, there is only one instance of Type per application domain.

此程式碼範例會使用 MethodInfo 來叫用字串 "Hello,World!" 上的 Substring 方法,並顯示結果。The code example uses the MethodInfo to invoke the Substring method on the string "Hello, World!", and displays the result.

#using <System.dll>

using namespace System;
using namespace System::Reflection;

void main()
{
    // Get a Type object representing the System.String type.
    Type^ t = String::typeid;

    MethodInfo^ substr = t->GetMethod("Substring", 
        gcnew array<Type^> { int::typeid, int::typeid });

    Object^ result = 
        substr->Invoke("Hello, World!", gcnew array<Object^> { 7, 5 });
    Console::WriteLine("{0} returned \"{1}\".", substr, result);
}

/* This code example produces the following output:

System.String Substring(Int32, Int32) returned "World".
 */
using System;
using System.Reflection;

class Example
{
    static void Main()
    {
        Type t = typeof(String);

        MethodInfo substr = t.GetMethod("Substring", 
            new Type[] { typeof(int), typeof(int) });

        Object result = 
            substr.Invoke("Hello, World!", new Object[] { 7, 5 });
        Console.WriteLine("{0} returned \"{1}\".", substr, result);
    }
}

/* This code example produces the following output:

System.String Substring(Int32, Int32) returned "World".
 */
Imports System.Reflection

Module Example
    
    Sub Main() 

        Dim t As Type = GetType(String)
        
        Dim substr As MethodInfo = t.GetMethod("Substring", _
            New Type() { GetType(Integer), GetType(Integer) })
        
        Dim result As Object = _ 
            substr.Invoke("Hello, World!", New Object() { 7, 5 })
        Console.WriteLine("{0} returned ""{1}"".", substr, result)
    
    End Sub 
End Module

' This code example produces the following output:
'
'System.String Substring(Int32, Int32) returned "World".

備註

TypeSystem.Reflection 功能的根,而且是存取中繼資料的主要方式。Type is the root of the System.Reflection functionality and is the primary way to access metadata. 使用 Type 的成員,即可取得類型宣告的相關資訊、關於類型的成員(例如,函式、方法、欄位、屬性和類別的事件),以及部署類別的模組和元件。Use the members of Type to get information about a type declaration, about the members of a type (such as the constructors, methods, fields, properties, and events of a class), as well as the module and the assembly in which the class is deployed.

程式碼不需要任何許可權,就能使用反映來取得有關類型及其成員的資訊,而不論其存取層級為何。No permissions are required for code to use reflection to get information about types and their members, regardless of their access levels. 程式碼不需要任何許可權,就能使用反映來存取公用成員,或是存取層級會在一般編譯期間顯示的其他成員。No permissions are required for code to use reflection to access public members, or other members whose access levels would make them visible during normal compilation. 不過,為了讓您的程式碼使用反映來存取通常無法存取的成員(例如私用或內部方法),或您的類別未繼承之類型的受保護欄位,您的程式碼必須具有 ReflectionPermissionHowever, in order for your code to use reflection to access members that would normally be inaccessible, such as private or internal methods, or protected fields of a type your class does not inherit, your code must have ReflectionPermission. 請參閱反映的安全性考慮See Security Considerations for Reflection.

Type 是允許多個執行的抽象基類。Type is an abstract base class that allows multiple implementations. 系統一律會提供衍生類別 RuntimeTypeThe system will always provide the derived class RuntimeType. 在反映中,所有以 word 執行時間開頭的類別,只會針對系統中的每個物件建立一次,並支援比較作業。In reflection, all classes beginning with the word Runtime are created only once per object in the system and support comparison operations.

注意

在多執行緒案例中,請勿鎖定 Type 物件,以便同步處理 static 資料的存取。In multithreading scenarios, do not lock Type objects in order to synchronize access to static data. 其他您沒有控制項的程式碼,也可能會鎖定您的類別類型。Other code, over which you have no control, might also lock your class type. 這可能會導致鎖死。This might result in a deadlock. 相反地,藉由鎖定私用 static 物件來同步處理靜態資料的存取。Instead, synchronize access to static data by locking a private static object.

注意

衍生類別可以存取呼叫程式碼之基類的受保護成員。A derived class can access protected members of the calling code's base classes. 此外,也允許存取呼叫程式碼之元件的元件成員。Also, access is allowed to assembly members of the calling code's assembly. 做為規則,如果您允許在早期繫結程式碼中存取,則您也可以在晚期繫結程式碼中存取。As a rule, if you are allowed access in early-bound code, then you are also allowed access in late-bound code.

注意

擴充其他介面的介面不會繼承擴充介面中定義的方法。Interfaces that extend other interfaces do not inherit the methods defined in the extended interfaces.

類型物件代表哪些類型?What types does a Type object represent?

這個類別是安全線程;多個執行緒可以同時讀取此類型的實例。This class is thread safe; multiple threads can concurrently read from an instance of this type. Type 類別的實例可以代表下列任何一種類型:An instance of the Type class can represent any of the following types:

  • 類別Classes

  • 值類型Value types

  • 陣列Arrays

  • 介面Interfaces

  • 列舉Enumerations

  • 委派Delegates

  • 結構化泛型型別和泛型型別定義Constructed generic types and generic type definitions

  • 型別引數,以及結構化泛型型別、泛型型別定義和泛型方法定義的型別參數Type arguments and type parameters of constructed generic types, generic type definitions, and generic method definitions

正在抓取類型物件Retrieving a Type object

與特定類型相關聯的 Type 物件可以透過下列方式取得:The Type object associated with a particular type can be obtained in the following ways:

  • 實例 Object.GetType 方法會傳回代表實例類型的 Type 物件。The instance Object.GetType method returns a Type object that represents the type of an instance. 由於所有 managed 類型都是衍生自 Object,因此可以在任何類型的實例上呼叫 GetType 方法。Because all managed types derive from Object, the GetType method can be called on an instance of any type.

    下列範例會呼叫 Object.GetType 方法,以判斷物件陣列中每個物件的執行時間類型。The following example calls the Object.GetType method to determine the runtime type of each object in an object array.

    using namespace System;
    
    void main()
    {
       array<Object^>^ values = { "word", true, 120, 136.34 };
       for each (Object^ value in values)
          Console::WriteLine("{0} - type {1}", value, 
                            value->GetType()->Name);
    }
    // The example displays the following output:
    //       word - type String
    //       True - type Boolean
    //       120 - type Int32
    //       136.34 - type Double
    
    using System;
    
    public class Example
    {
       public static void Main()
       {
          object[] values = { "word", true, 120, 136.34, 'a' };
          foreach (var value in values)
             Console.WriteLine("{0} - type {1}", value, 
                               value.GetType().Name);
       }
    }
    // The example displays the following output:
    //       word - type String
    //       True - type Boolean
    //       120 - type Int32
    //       136.34 - type Double
    //       a - type Char
    
    Module Example
       Public Sub Main()
          Dim values() As Object = { "word", True, 120, 136.34, "a"c }
          For Each value In values
             Console.WriteLine("{0} - type {1}", value, 
                               value.GetType().Name)
          Next
       End Sub
    End Module
    ' The example displays the following output:
    '       word - type String
    '       True - type Boolean
    '       120 - type Int32
    '       136.34 - type Double
    '       a - type Char
    
  • 靜態 Type.GetType 方法會傳回代表其完整名稱所指定之類型的 Type 物件。The static Type.GetType methods return a Type object that represents a type specified by its fully qualified name.

  • Module.GetTypesModule.GetTypeModule.FindTypes 方法會傳回 Type 物件,代表模組中定義的類型。The Module.GetTypes, Module.GetType, and Module.FindTypes methods return Type objects that represent the types defined in a module. 第一個方法可以用來取得模組中定義之所有公用和私用類型的 Type 物件陣列。The first method can be used to obtain an array of Type objects for all the public and private types defined in a module. (您可以透過 Assembly.GetModuleAssembly.GetModules 方法,或透過 Type.Module 屬性,取得 Module 的實例)。(You can obtain an instance of Module through the Assembly.GetModule or Assembly.GetModules method, or through the Type.Module property.)

  • System.Reflection.Assembly 物件包含多個方法來抓取元件中定義的類別,包括 Assembly.GetTypeAssembly.GetTypesAssembly.GetExportedTypesThe System.Reflection.Assembly object contains a number of methods to retrieve the classes defined in an assembly, including Assembly.GetType, Assembly.GetTypes, and Assembly.GetExportedTypes.

  • FindInterfaces 方法會傳回類型所支援之介面類別型的已篩選清單。The FindInterfaces method returns a filtered list of interface types supported by a type.

  • GetElementType 方法會傳回代表元素的 Type 物件。The GetElementType method returns a Type object that represents the element.

  • GetInterfacesGetInterface 方法會傳回代表類型所支援之介面類別型的 Type 物件。The GetInterfaces and GetInterface methods return Type objects representing the interface types supported by a type.

  • GetTypeArray 方法會傳回 Type 物件的陣列,代表任意物件集合所指定的類型。The GetTypeArray method returns an array of Type objects representing the types specified by an arbitrary set of objects. 物件是以 Object類型的陣列來指定。The objects are specified with an array of type Object.

  • GetTypeFromProgIDGetTypeFromCLSID 方法是針對 COM 互通性所提供。The GetTypeFromProgID and GetTypeFromCLSID methods are provided for COM interoperability. 它們會傳回代表 ProgIDCLSID所指定類型的 Type 物件。They return a Type object that represents the type specified by a ProgID or CLSID.

  • 針對互通性提供 GetTypeFromHandle 方法。The GetTypeFromHandle method is provided for interoperability. 它會傳回代表類別控制碼所指定之類型的 Type 物件。It returns a Type object that represents the type specified by a class handle.

  • C# typeof 運算子、 C++ typeid 運算子和 Visual Basic GetType 運算子會取得類型的 Type 物件。The C# typeof operator, the C++ typeid operator, and the Visual Basic GetType operator obtain the Type object for a type.

  • MakeGenericType 方法會傳回代表結構化泛型型別的 Type 物件,如果其 ContainsGenericParameters 屬性傳回 true則為開放式結構化類型,否則為封閉的結構化類型。The MakeGenericType method returns a Type object representing a constructed generic type, which is an open constructed type if its ContainsGenericParameters property returns true, and a closed constructed type otherwise. 只有當泛型型別已關閉時,才可以將它具現化。A generic type can be instantiated only if it is closed.

  • MakeArrayTypeMakePointerTypeMakeByRefType 方法會傳回 Type 物件,分別代表指定類型的陣列、指定類型的指標,以及參考參數的類型(在C#refByRef)。The MakeArrayType, MakePointerType, and MakeByRefType methods return Type objects that represent, respectively, an array of a specified type, a pointer to a specified type, and the type of a reference parameter (ref in C#, ByRef in Visual Basic).

比較類型物件是否相等Comparing type objects for equality

代表類型的 Type 物件是唯一的;也就是說,只有在代表相同類型的情況下,兩個 Type 的物件參考才會參考相同的物件。A Type object that represents a type is unique; that is, two Type object references refer to the same object if and only if they represent the same type. 這可讓您使用參考相等比較 Type 物件。This allows for comparison of Type objects using reference equality. 下列範例會比較代表整數值數目的 Type 物件,以判斷它們是否屬於相同的類型。The following example compares the Type objects that represent a number of integer values to determine whether they are of the same type.

using namespace System;

void main()
{
   Int64 number1 = 1635429;
   Int32 number2 = 16203;
   double number3 = 1639.41;
   Int64 number4 = 193685412;
   
   // Get the type of number1.
   Type^ t = number1.GetType();
   
   // Compare types of all objects with number1.
   Console::WriteLine("Type of number1 and number2 are equal: {0}",
                      Object::ReferenceEquals(t, number2.GetType()));
