How to strip some parts out of a string

How to strip some parts out of a string

  Based on your picture I'm concerned the data might not be in the ASCII format. Secondly, could you paste a Base64 encoding of your array "data". It might better help us understand what's happening. What do you expect to be in this string s

  Thanks man this tip solve me problem

   

  Here is the solution

   lblData.Text = args.Text.Substring(args.Text.LastIndexOf(@"\") + 14).ToString() ;

  Use the System.Convert.ToBase64String string. It'll convert any byte array to a Base64 encoded string, for future reference. Base64 strings are easier to send on web pages and forums and people can decode them to get the original data back.

  Sorry may be i am not explain the question nicely

  This data comes from a sever upon my request into two format:

  1. As an array with dynamic length (It depends on the data i request)

  2. As a string text containing the the value like these ( 55.62, 14252252, 152.36, ....etc) but with special characters

  Please see this http://www.swa7.com/upload/uploading/StringFormat.jpg

  to get clear picture about what i want to do.

  Thanks

  You can use LastIndexOf string method.

  In your case will be someting like str.Substring(str.LastIndexOf('\') + 2)

  While I think that the format of the binary data would be useful in developing a more elegant solution here is the short term solution: You can use this regex to parse numbers from the end of the string.

     Sub Main()
        Dim numericRegex As New Regex("\d+(\.\d+) $", RegexOptions.ExplicitCapture Or RegexOptions.RightToLeft)
  
        For Each text As String In New String() {"3.1", "x\0x\0x\0x\0x\0x\0x\0x40.5", "x\0x\0x\0x\0x\0\b\0\a4463747"}
           Dim m As Match = numericRegex.Match(text)
  
           If m.Success Then Console.WriteLine(m.Value)
        Next
  
        Console.ReadLine()
     End Sub
  

  I put on explicit capture just because it's a bit more performant and right to left since we're dealing with the end of the string why not start there, no Hope that helps!

  If you know the exact size of the string you can do something like this;

  mystring.Substring(10, 5)

  My guess is your string is not always the same size so you can use

  using System.Text.RegularExpressions;
  ....
  Regex re = new Regex("[-9]", RegexOptions.Compiled);
  if (re.IsMatch(str)) {
  ...
  }

  Sorry if I am missing something but why are you using the Encoding.ASCII.GetString(data)

  what/where is "data" coming from

  I will try to use Base64 and give you a feedback
