Type.GetInterfaceMap(Type) 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Type.cs

返回指定接口类型的接口映射。

public:
 virtual System::Reflection::InterfaceMapping GetInterfaceMap(Type ^ interfaceType);

public virtual System.Reflection.InterfaceMapping GetInterfaceMap (Type interfaceType);

abstract member GetInterfaceMap : Type -> System.Reflection.InterfaceMapping
override this.GetInterfaceMap : Type -> System.Reflection.InterfaceMapping

Public Overridable Function GetInterfaceMap (interfaceType As Type) As InterfaceMapping

参数

interfaceType

Type

要检索其映射的接口类型。

返回

InterfaceMapping

表示 interfaceType 的接口映射的对象。

例外

ArgumentException

当前类型未实现 interfaceType。

- 或 -

interfaceType 参数未引用接口。

- 或 -

当前实例或 interfaceType 参数是开放式泛型类型；即，ContainsGenericParameters 属性将返回 true。

- 或 -

interfaceType 是一个泛型接口，而当前类型是一个数组类型。

ArgumentNullException

interfaceType 为 null。

InvalidOperationException

当前 Type 表示泛型类型参数；即， IsGenericParameter 为 true。

NotSupportedException

基类不支持调用的方法。 派生类必须提供一个实现。

示例

以下示例调用 GetInterfaceMap 方法以确定接口如何 IFormatProvider 映射到 CultureInfo 方法，以及接口如何 IAppDomainSetup 映射到 AppDomainSetup 属性。 请注意，由于 IAppDomainSetup 接口定义了一组属性，因此返回 InterfaceMapping 的对象包含属性的 get 和 set 访问器的独立 MethodInfo 对象。

using System;
using System.Globalization;
using System.Reflection;

public class Example
{
   public static void Main()
   {
      Type[] interf = { typeof(IFormatProvider), typeof(IAppDomainSetup) };
      Type[] impl = { typeof(CultureInfo), typeof(AppDomainSetup) };

      for (int ctr = 0; ctr < interf.Length; ctr++)
         ShowInterfaceMapping(interf[ctr], impl[ctr]);
   }

   private static void ShowInterfaceMapping(Type intType, Type implType)
   {
      InterfaceMapping map = implType.GetInterfaceMap(intType);
      Console.WriteLine("Mapping of {0} to {1}: ", map.InterfaceType, map.TargetType);
      for (int ctr = 0; ctr < map.InterfaceMethods.Length; ctr++) {
         MethodInfo im = map.InterfaceMethods[ctr];
         MethodInfo tm = map.TargetMethods[ctr];
         Console.WriteLine("   {0} --> {1}", im.Name,tm.Name);
      }
      Console.WriteLine();
   }
}

注解

接口映射表示如何将接口映射到实现该接口的类上的实际成员。

如果当前 Type 表示构造的泛型类型，则类型参数将替换为此方法返回的 元素 InterfaceMapping 中的相应类型参数。
