ParameterInfo.Name Propriété

public:
 virtual property System::String ^ Name { System::String ^ get(); };

public virtual string Name { get; }

public virtual string? Name { get; }

member this.Name : string

Public Overridable ReadOnly Property Name As String

Valeur de propriété

Nom simple de ce paramètre.

Exemples

L’exemple suivant montre comment obtenir ParameterInfo des objets pour les paramètres d’une méthode, puis utiliser la Name propriété pour obtenir les noms de paramètres.

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;
}

Remarques

Cette propriété utilise le champ protégé NameImpl et dépend d’un indicateur de métadonnées facultatif qui peut ne pas être disponible dans tous les compilateurs.

Pour obtenir le ParameterInfo tableau, commencez par obtenir la méthode ou le constructeur, puis appelez la MethodBase.GetParameters méthode.
