There's this string:

Take a= number
b= string
Intercept Method 1:
int a = Convert.ToInt32(txt1.Text.Trim().Replace('[', ']').Split(']')[1]); string b = txt1.Text.Trim().Replace('[', ']').Split(']')[2];
Interception Method 2:
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");
How to write an array
/// ///Return an array of strings/// /// /// public string[] ReturnIDAndName(string str) { string[] stringArray = new string[2]; Regex reg = new Regex(@"([^]+)\](.*) "); stringArray[0]= reg.Match(str).Groups[1].Value; stringArray[1] = reg.Match(str).Groups[2].Value; return stringArray; } /// ///Intercept string number/// public int ReturnId(string str) { try { if (string.IsNullOrEmpty(str)) { return 0; } Regex regex = new Regex("(?
