Get rid of special characters

Get rid of special characters

• Sean D Wright

  You wish to remove random characters from the files, or from the filenames In the latter, you should make program A to generate valid filenames only.
  
  In the previous case, here are the steps:
  
  First of all, add a Timer component to your program. Add appropriate interval, and enable it. Create Tick event handler, it should perform (at least) the following:
  
  1) Create System.IO.DirectoryInfo
  ex: DirectoryInfo dir = new DirectoryInfo(Enviroment.CurrentDirectory);
  
  2) Get the filenames inside your directory
  FileInfo[] files = dir.GetFiles();
  
  3) Now work the files in foreach loop, one file at the time
  
  4) Open the file using TextReader or such
  TextReader reader = new SreamReader(theFile.FullName); //theFile is a FileInfo object in foreach loop
  
  5) read contents of the file inside StringBuilder object (for enhanced performance), whole file to end or line at a time in a loop, its your call
  
  6) then use Replace method of the StringBuilder to replace the characters of your choice with empty strings, thus remove them: strBuild.Replace("#", "");
  
  7) now construct the new file from replaced strings, and write it to the file using TextWriter.
  
  Hope this helps---

  Hi,

  I think ruhan's post will give enough information how to internally handle files and remove special characters from file...
  
  Here i will like to add few points...
  Each of your file has goes through a step of sequence that should be maintained...

  Mean program B should not access file until its processed by program C and proram C should accessed only newly created files...

  You can handle this by many ways but what i would like to do simply is...

  I will create two folders for example
  
  1)NewFiles
  2)ModifiedFiles
  
  Now program A will create files and put them NewFiles Direcotry
  Program C will will Load files from NewFile directory and put them in ModifiedFiles directory
  Now program B will only looking files from directory ModifiedFiles and get input from them and then if these files are not needed in any case then delete then or put them in some back or processed file folder.
  
  Hope this help.

  Would it be better if I scheduled the C# program using the task scheduler rather than the ticker
