remove specified character [] from string

  No problem. These are forums with a buffet of answers to pick from.

  I got confused a few times myself.

  So, indeed! I only readed the first section of the topic start post and started writing a sample. But indeed in the seconds section he/she asks something else.
  
  Sorry for my reply Andreas, i looks like we both answered the question
  Thank you very much for the notice!

  Some self-explaing code:
  
  

  public void ExcludeCharacters( string y, char[] x ); {     StringBuilder buffer = new StringBuilder( y.Lenght );         for( int i = 0; i < y.Lenght; i++ )     {         bool isBad = false;         char toCheck = y[ i ];                 foreach(Char badCharacter in x )         {             if( toCheck.Equals( badCharacter ) )             {                 isBad = true;                 break;             }         }                 if( !isBad )         {             buffer.Append( toCheck );         }     }         return buffer.ToString(); }

  I also wrote an example so now you can pick and choose. When I saw the PJs post I rewrote it to be a similar function.

  private String ExcludeCharacters(String strText, Char[] arrValidChars)
  {
  // Create a string of the char array to be able to use IndexOf
  String strValidChars = new String(arrValidChars);
  
  // The filtered result
  StringBuilder strResult = new StringBuilder();
  
  // Check every character in the source string
  foreach (Char c in strText.ToCharArray())
  {
  // Is it part of the allowed characters
  if (strValidChars.IndexOf(c) >= 0)
  {
  // Yes, add it to the result
  strResult.Append(c);
  }
  }

  // Done
  return strResult.ToString();
  }

  I use a bit less own code, result is the same.

  Thank you very much andreas for you sample code!
  
  But you use a valid character array, sinds the topic starter want a invalid character array you example wouldn't work.

  I need to know How can I excluding any characters of a string except a specified set of characters defined by Char[ ].

  That is a double negation, exclude all except array, leads to include only array of chars

  so how can I return a string z  that contains only the characters belong to x and excluding all others

  The subject is opposite of the post.
