Public Overridable ReadOnly Property Name As String

Valor da propriedade

O nome simples desse parâmetro.

Exemplos

O exemplo a seguir mostra como obter ParameterInfo objetos para os parâmetros de um método e, em seguida, usar a Name propriedade para obter os nomes de parâmetro.

using namespace System;
using namespace System::Reflection;
using namespace System::Runtime::InteropServices;
public ref class parminfo
{
public:
   static void mymethod( int int1m, [Out]interior_ptr<String^> str2m, interior_ptr<String^> str3m )
   {
       *str2m = "in mymethod";
   }

};

int main()
{
   Console::WriteLine( "\nReflection.Parameterinfo" );
   
   //Get the ParameterInfo parameter of a function.
   //Get the type.
   Type^ Mytype = Type::GetType( "parminfo" );
   
   //Get and display the method.
   MethodBase^ Mymethodbase = Mytype->GetMethod( "mymethod" );
   Console::Write( "\nMymethodbase = {0}", Mymethodbase );
   
   //Get the ParameterInfo array.
   array<ParameterInfo^>^Myarray = Mymethodbase->GetParameters();
   
   //Get and display the name of each parameter.
   System::Collections::IEnumerator^ enum0 = Myarray->GetEnumerator();
   while ( enum0->MoveNext() )
   {
      ParameterInfo^ Myparam = safe_cast<ParameterInfo^>(enum0->Current);
      Console::Write( "\nFor parameter # {0}, the Name is - {1}", Myparam->Position, Myparam->Name );
   }

   return 0;
}

Comentários

Essa propriedade utiliza o campo protegido NameImpl e depende de um sinalizador de metadados opcional que pode não estar disponível em todos os compiladores.

Para obter a ParameterInfo matriz, primeiro obtenha o método ou o construtor e, em seguida, chame o MethodBase.GetParameters método .
