ProcessStartInfo.Arguments 屬性

定義

命名空間:

System.Diagnostics

組件:

netstandard.dll, System.Diagnostics.Process.dll

來源:

ProcessStartInfo.cs

取得或設定啟動應用程式時要使用的命令列參數集合。

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

屬性值

String

一個包含屬性中指定 FileName 要傳遞給目標應用程式的參數的單一字串。 預設為空字串（“”）。

範例

第一個範例會建立一個小型應用程式（argsecho.exe），將其參數回傳給主控台。 第二個範例則建立一個應用程式，用 argsecho.exe 來展示該性質的不同變體 Arguments 。

// 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();
        }
    }
}

備註

分配給該 Arguments 屬性的字串長度必須小於32,699。

參數會被目標應用程式解析與解讀，因此必須符合該應用程式的期望。 如下方範例所示，對於 .NET 應用程式，空格被解釋為多個參數之間的分隔符。 包含空格的單一參數必須被引號包圍，但這些引號不會延續到目標應用程式。 若要在最後解析的論點中加入引號，每個標記都要三重轉義。 如果你用這個屬性來設定命令列參數，必須 ArgumentList 不包含任何元素。

Arguments 且 ArgumentList 彼此獨立。 也就是說，指派給 Arguments 屬性的字串不會填滿整個 ArgumentList 集合，集合的 ArgumentList 成員也不會被指派到該 Arguments 屬性。

這很重要
