Exemples

Le premier exemple crée une petite application (argsecho.exe) qui renvoie ses arguments à la console. Le deuxième exemple crée une application qui appelle argsecho.exe pour illustrer différentes variantes pour la Arguments propriété.

// Place this code into a console project called ArgsEcho to build the argsecho.exe target

using namespace System;

int main(array<System::String ^> ^args)
{
    Console::WriteLine("Received the following arguments:\n");

    for (int i = 0; i < args->Length; i++)
    {
        Console::WriteLine("[" + i + "] = " + args[i]);
    }

    Console::WriteLine("\nPress any key to exit");
    Console::ReadLine();
    return 0;
}

// Place this code into a console project called ArgsEcho to build the argsecho.exe target

using System;

namespace StartArgs
{
    class ArgsEcho
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Received the following arguments:\n");

            for (var i = 0; i < args.Length; i++)
            {
                Console.WriteLine($"[{i}] = {args[i]}");
            }

            Console.WriteLine("\nPress any key to exit");
            Console.ReadLine();
        }
    }
}

Remarques

La longueur de la chaîne affectée à la Arguments propriété doit être inférieure à 32 699.

Les arguments étant analysés et interprétés par l'application cible, ils doivent correspondre aux attentes de cette application. Pour les applications .NET, comme illustré dans les exemples ci-dessous, les espaces sont interprétés comme un séparateur entre plusieurs arguments. Un argument unique qui comprend des espaces doit être placé entre guillemets, mais les guillemets ne sont pas transmises à l'application cible. Pour inclure des guillemets dans l’argument analysé final, triple-échappement chaque marque. Si vous utilisez cette propriété pour définir des arguments de ligne de commande, ArgumentList ne doit contenir aucun élément.

Arguments et ArgumentList, qui est pris en charge à partir de .NET Core 2.1 et .NET Standard 2.1, sont indépendants les uns des autres. Autrement dit, la chaîne affectée à la Arguments propriété ne remplit pas la ArgumentList collection et les membres de la ArgumentList collection ne sont pas affectés à la Arguments propriété .
