Backslash and quote in command-line arguments

Question

Is the following behaviour some feature or a bug in C# .NET?

Test application:

using System;
using System.Linq;

namespace ConsoleApplication1
{
             


        

Answer 1

I have escaped the problem the other way...

Instead of getting arguments already parsed I am getting the arguments string as it is and then I am using my own parser:

static void Main(string[] args)
{
    var param = ParseString(Environment.CommandLine);
    ...
}

// The following template implements the following notation:
// -key1 = some value   -key2 = "some value even with '-' character "  ...
private const string ParameterQuery = "\\-(?\\w+)\\s*=\\s*(\"(?[^\"]*)\"|(?[^\\-]*))\\s*";

private static Dictionary ParseString(string value)
{
   var regex = new Regex(ParameterQuery);
   return regex.Matches(value).Cast().ToDictionary(m => m.Groups["key"].Value, m => m.Groups["value"].Value);
}

This concept lets you type quotes without the escape prefix.
