Question

please help me this problem.
I want to split “-action=1” to “action” and “1”.

string pattern = @"^-(\S+)=(\S+)$";
Regex regex = new Regex(pattern);
string myText = "-action=1";
string[] result = regex.Split(myText);

I don’t know why result have length=4.

result[0] = ""
result[1] = "action"
result[2] = "1"
result[3] = ""

Please help me.

P/S: I am using .NET 2.0.

Thanks.

Hello, I tested with string: @”-destination=C:\Program Files\Release” but it have inaccurate result, I don’t understand why result’s length = 1. I think because it has a white space in string.

I want to split it to “destination” & “C:\Program Files\Release”

More info: This is my requirement:
-string1=string2 -> split it to: string1 & string2.
In string1 & string2 don’t contain characters: ‘-‘, ‘=’, but they can contain white space.

Please help me. Thanks.

Try this (updated to add Regex.Split):

string victim = "-action=1";
string[] stringSplit = victim.Split("-=".ToCharArray());
string[] regexSplit = Regex.Split(victim, "[-=]");

EDIT: Using your example:

string input = @"-destination=C:\Program Files\Release -action=value";
foreach(Match match in Regex.Matches(input, @"-(?<name>\w+)=(?<value>[^=-]*)"))
{
    Console.WriteLine("{0}", match.Value);
    Console.WriteLine("\tname  = {0}", match.Groups["name" ].Value);
    Console.WriteLine("\tvalue = {0}", match.Groups["value"].Value);
}
Console.ReadLine();

Of course, this code have issues if your path contains - character
