You can try something like this:

var data = "[asd][dfhg][asfsa243]";

var re = new Regex(@"\[([^\]]*)\]");

var matches = re.Matches(data);

for (int i = 0; i < matches.Count; i++ )
{
    var m = matches[i];
    Console.WriteLine(m.Groups[1]);
}

Console.ReadLine();

This outputs:

asd
dfhg
asfsa243

The regular expression \[([^\]]*)\] matches zero or more occurrences of a character that isn’t the ] character and which is between a pair of square brackets ([ and ])
