ProcessStartInfo.Arguments Properti

Definisi

Ruang nama:

System.Diagnostics

Rakitan:

System.Diagnostics.Process.dll

Sumber:

ProcessStartInfo.cs

Mendapatkan atau mengatur kumpulan argumen baris perintah yang akan digunakan saat memulai aplikasi.

public:
 property System::String ^ Arguments { System::String ^ get(); void set(System::String ^ value); };

public string Arguments { get; set; }

member this.Arguments : string with get, set

Public Property Arguments As String

Nilai Properti

String

String tunggal yang berisi argumen untuk diteruskan ke aplikasi target yang ditentukan dalam FileName properti . Defaultnya adalah string kosong ("").

Contoh

Contoh pertama membuat aplikasi kecil (argsecho.exe) yang menggaungkan argumennya ke konsol. Contoh kedua membuat aplikasi yang memanggil argsecho.exe untuk menunjukkan variasi yang berbeda untuk Arguments properti .

// 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();
        }
    }
}

Keterangan

Panjang string yang ditetapkan ke Arguments properti harus kurang dari 32.699.

Argumen diurai dan ditafsirkan oleh aplikasi target, jadi harus selaras dengan harapan aplikasi tersebut. Untuk aplikasi .NET seperti yang ditunjukkan dalam Contoh di bawah ini, spasi ditafsirkan sebagai pemisah di antara beberapa argumen. Argumen tunggal yang menyertakan spasi harus dikelilingi oleh tanda kutip, tetapi tanda kutip tersebut tidak dibawa ke aplikasi target. Untuk menyertakan tanda kutip dalam argumen yang diurai akhir, tiga kali lipat untuk setiap tanda. Jika Anda menggunakan properti ini untuk mengatur argumen baris perintah, ArgumentList tidak boleh berisi elemen apa pun.

Arguments dan ArgumentList, yang didukung dimulai dengan .NET Core 2.1 dan .NET Standard 2.1, independen satu sama lain. Artinya, string yang ditetapkan ke Arguments properti tidak mengisi ArgumentList koleksi, dan anggota ArgumentList koleksi tidak ditetapkan ke Arguments properti .
