Public Property Arguments As String
属性值
一个字符串,其中包含要传递给属性中指定的 FileName 目标应用程序的参数。 默认值为空字符串(“)。
- 属性
示例
第一个示例创建一个小型应用程序(argsecho.exe),该应用程序将其参数回显到控制台。 第二个示例创建一个应用程序,该应用程序调用 argsecho.exe 来演示属性的不同变体 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($"[{i}] = {args[i]}");
}
Console.WriteLine("\nPress any key to exit");
Console.ReadLine();
}
}
}
' Place this code into a console project called ArgsEcho to build the argsecho.exe target
Module Module1
Sub Main()
Dim i As Integer = 0
For Each s As String In My.Application.CommandLineArgs
Console.WriteLine($"[{i}] = {s}")
i = i + 1
Next
Console.WriteLine(Environment.NewLine + "Press any key to exit")
Console.ReadLine()
End Sub
End Module

// console application named argsecho.exe.

// Output of ArgsEcho:

startInfo.Arguments = "/a";
Process.Start(startInfo);
// Start with multiple arguments separated by spaces.
// Output of ArgsEcho:
// [0] = /a
// [1] = /b
// [2] = c:\temp
startInfo.Arguments = "/a /b c:\\temp";
Process.Start(startInfo);

// Output of ArgsEcho:
// [0] = /a
// [1] = literal string arg
startInfo.Arguments = "/a \"literal string arg\"";
Process.Start(startInfo);

// that is, as separate arguments. Equivalent verbatim string is @"/a /b:""string with quotes"""

注解
分配给属性 Arguments 的字符串长度必须小于 32,699。
参数由目标应用程序分析和解释,因此必须与该应用程序的预期保持一致。 对于以下示例中所示的 .NET 应用程序,空格被解释为多个参数之间的分隔符。 包含空格的单个参数必须用引号括起来,但这些引号不会传递到目标应用程序。 若要在最终分析的参数中包含引号,请对每个标记进行三次转义。 如果使用此属性设置命令行参数, ArgumentList 则不得包含任何元素。
Arguments 彼此 ArgumentList 独立。 也就是说,分配给该属性的 Arguments 字符串不会填充 ArgumentList 集合,并且不会将集合的成员 ArgumentList 分配给该 Arguments 属性。
