属性

异常

当前类型未实现 interfaceTypeinterfaceType is not implemented by the current type.

-or- interfaceType 参数未引用接口。The interfaceType argument does not refer to an interface.

-or-

当前实例或 interfaceType 参数是开放式泛型类型;即,ContainsGenericParameters 属性将返回 trueThe current instance or interfaceType argument is an open generic type; that is, the ContainsGenericParameters property returns true.

-or-

interfaceType 是一个泛型接口,而当前类型是一个数组类型。interfaceType is a generic interface, and the current type is an array type.

interfaceTypenullinterfaceType is null.

当前 Type 表示泛型类型参数;即, IsGenericParametertrueThe current Type represents a generic type parameter; that is, IsGenericParameter is true.

基类不支持调用的方法。The invoked method is not supported in the base class. 派生类必须提供一个实现。Derived classes must provide an implementation.

示例

下面的GetInterfaceMap示例调用方法来确定IFormatProvider接口如何映射到CultureInfo方法,以及IAppDomainSetup接口如何映射到AppDomainSetup属性。The following example calls the GetInterfaceMap method to determine how the IFormatProvider interface maps to CultureInfo methods, and how the IAppDomainSetup interface maps to AppDomainSetup properties. 请注意,由于IAppDomainSetup接口定义了一组属性,因此,返回InterfaceMapping的对象为属性的 get 和 set 访问器包含单独MethodInfo的对象。Note that, because the IAppDomainSetup interface defines a set of properties, the returned InterfaceMapping object includes separate MethodInfo objects for a property's get and set accessors.

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

接口映射表示接口如何映射到实现该接口的类上的实际成员。The interface map denotes how an interface is mapped into the actual members on a class that implements that interface.

如果当前Type表示构造泛型类型,则在此方法返回的的InterfaceMapping元素中,类型参数将替换为相应的类型参数。If the current Type represents a constructed generic type, type parameters are replaced by the appropriate type arguments in the elements of the InterfaceMapping returned by this method.
