Type.GetInterfaces 方法

public:
 abstract cli::array <Type ^> ^ GetInterfaces();

public abstract Type[] GetInterfaces ();

abstract member GetInterfaces : unit -> Type[]

Public MustOverride Function GetInterfaces () As Type()

返回

Type[]

表示由当前 Type 实现或继承的所有接口的 Type对象数组。

• 或 - 如果没有由当前 Type 实现或继承的接口，则为 Type 类型的空数组。

实现

例外

示例

下面的示例获取指定类的类型，并显示该类型实现或继承的所有接口。 若要编译Visual Basic，请使用以下编译器命令：

vbc type_getinterfaces1.vb /r:System.Web.dll /r:System.dll

using namespace System;
using namespace System::Collections::Generic;

void main()
{
    Console::WriteLine("\r\nInterfaces implemented by Dictionary<int, String^>:\r\n");
     
    for each (Type^ tinterface in Dictionary<int, String^>::typeid->GetInterfaces())
    {
        Console::WriteLine(tinterface->ToString());
    }

    //Console::ReadLine()      // Uncomment this line for Visual Studio. 
}

/* This example produces output similar to the following:

Interfaces implemented by Dictionary<int, String^>:

System.Collections.Generic.IDictionary`2[System.Int32,System.String]
System.Collections.Generic.ICollection`1[System.Collections.Generic.KeyValuePair`2[System.Int32,System.String]]
System.Collections.Generic.IEnumerable`1[System.Collections.Generic.KeyValuePair`2[System.Int32,System.String]]
System.Collection.IEnumerable
System.Collection.IDictionary
System.Collection.ICollection
System.Runtime.Serialization.ISerializable
System.Runtime.Serialization.IDeserializationCallback
 */

using System;
using System.Collections.Generic;

public class Example
{
    static void Main()
    {
        Console.WriteLine("\r\nInterfaces implemented by Dictionary<int, string>:\r\n");

        foreach (Type tinterface in typeof(Dictionary<int, string>).GetInterfaces())
        {
            Console.WriteLine(tinterface.ToString());
        }

        //Console.ReadLine()      // Uncomment this line for Visual Studio.
    }
}

Public Class Example

    Shared Sub Main()

        For Each tinterface As Type In GetType(Dictionary(Of Integer, String)).GetInterfaces()

            Console.WriteLine(tinterface.ToString())

        Next

        'Console.ReadLine()      ' Uncomment this line for Visual Studio. 
    End Sub

注解

方法不按特定顺序（如字母顺序或声明顺序 GetInterfaces ）返回接口。 代码不得依赖于接口的返回顺序，因为该顺序会有所不同。

如果当前 Type 表示构造的泛型类型，则此方法返回对象 Type ，类型参数替换为相应的类型参数。

如果当前 表示泛型类型或泛型方法的定义中的类型参数，则此方法将搜索接口约束以及从类或接口约束继承 Type 的任何接口。
