   Hi
  
  I want to extract sustrings from a string and want to store in an array.
  The string is dynamic it will change but the criteria to extract substring is same.
  say for example a string str="something is [!better] than [!nothing]"
  so i need to extract [!better] and [!nothing] from the string and store it in a string array, the string is dynamic it changes but i need to extract data between [ and ] including both the square brackets.
  If anybody can send any sample code, I will be very thankfull.
  Thanks

  Hi Ansari,
  
  Put your string in 'str' and your parts will be in 'parts' List, at the end of the code :

  string str = "one [str1] two [str2]"; // strings in [] are parts
  List<string> parts = new List<string>(); // saves parts
  
  int start, // location of '['
      end = 0; // location of ']'
  while ((start = str.IndexOf('[',end)) != -1) // while there is another '[' in the string
  {
      end = str.IndexOf(']', start);
      if (end == -1) // if there is no ']'
          break;
  
      parts.Add(str.Substring(start, end-start+1)); // add current part
  }
  
  MessageBox.Show(parts[0]); // shows the first part
