Exemplos

O exemplo a seguir obtém o MemberFilter delegado, passa-o como um parâmetro para o FindMembers método e exibe os métodos e seus atributos da String classe que começam com a letra "c", desconsiderando o caso.

using namespace System;
using namespace System::Collections;
using namespace System::Reflection;
using namespace System::Security;
int main()
{
   try
   {
      MemberFilter^ myFilter = Type::FilterNameIgnoreCase;
      Type^ myType = System::String::typeid;
      array<MemberInfo^>^myMemberinfo1 = myType->FindMembers( static_cast<MemberTypes>(MemberTypes::Constructor | MemberTypes::Method), static_cast<BindingFlags>(BindingFlags::Public | BindingFlags::Static | BindingFlags::Instance), myFilter, "C*" );
      IEnumerator^ myEnum = myMemberinfo1->GetEnumerator();
      while ( myEnum->MoveNext() )
      {
         MemberInfo^ myMemberinfo2 = safe_cast<MemberInfo^>(myEnum->Current);
         Console::Write( "\n {0}", myMemberinfo2->Name );
         MemberTypes Mymembertypes = myMemberinfo2->MemberType;
         Console::WriteLine( " is a {0}", Mymembertypes );
      }
   }
   catch ( ArgumentNullException^ e )

      Console::Write( "ArgumentNullException : {0}", e->Message );
   }
   catch ( SecurityException^ e ) 
   {

Comentários

Esse campo contém uma referência ao delegado usado pelo FindMembers método. O método encapsulado por esse delegado usa dois parâmetros: o primeiro é um MemberInfo objeto e o segundo é um Object . O método determina se o MemberInfo objeto corresponde aos critérios especificados pelo Object . O Object é atribuído um valor de cadeia de caracteres, que pode incluir um caractere curinga "*" à direita. Há suporte apenas para correspondência de cadeia de caracteres final de caractere curinga.

Por exemplo, o Object valor "ByTe *" pode ser atribuído a ele. Nesse caso, quando o FilterName delegado é invocado, ele retornará true somente se o método representado pelo MemberInfo objeto tiver um nome que comece com "byte", ignorando maiúsculas e minúsculas.
