Ejemplos

En el ejemplo siguiente se obtiene el MemberFilter delegado, se pasa como un parámetro al FindMembers método y se muestran los métodos y sus atributos de la String clase que comienzan por la letra "c", sin tener en cuenta el 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 ( Exception^ e ) 
   {
      Console::Write( "Exception : {0}", e->Message );
   }

Comentarios

Este campo contiene una referencia al delegado utilizado por el FindMembers método . El método encapsulado por este delegado toma dos parámetros: el primero es un MemberInfo objeto y el segundo es .Object El método determina si el MemberInfo objeto coincide con los criterios especificados por .Object Object se asigna un valor de cadena, que puede incluir un carácter comodín "*" final. Solo se admite la coincidencia de cadenas de extremo comodín.

Por ejemplo, Object se puede asignar el valor "ByTe*". En ese caso, cuando se invoca al FilterName delegado, devolverá true solo si el método representado por el MemberInfo objeto tiene un nombre que comienza por "byte", ignorando mayúsculas y minúsculas.
