string str = "[number] string";Regex reg = new Regex(@"([^]+)\](.*) ");string a= Convert.ToInt32( reg.Match(str).Groups[1].Value);string b= Convert.ToInt32( reg.Match(str).Groups[2].Value);

Interception Method 3

string tempStr = "[number] character string"; string pattern = @"([\s§]<$)([\s\S]*)";Regex re = new Regex(pattern); string str1 = Regex.Replace(tempStr,pattern,"$1"); string str2 = Regex.Replace(tempStr, pattern, "$2");
