c# - How the edit a specified file (kinda text) with setting only the end of the file name -

my code looks this:

string text = file.readalltext("test.txt"); text = text.replace("some text", "new value"); file.writealltext("test.txt", text);      

i want edit 2 words, not one:

• from side *side
• and barcode *barcode

also there solution find file end of name instead of full name? because file name different ends string "_abc.desc"

you can find file end of it's name

       string partialname = "text";  // ending part of file name        directoryinfo hddirectoryinwhichtosearch = new directoryinfo(@"d:\");        fileinfo[] filesindir = hddirectoryinwhichtosearch.getfiles("*" + partialname + ".*");            // files matched name show in filesindir        foreach (fileinfo foundfile in filesindir)        {            string fullname = foundfile.fullname;            string text = file.readalltext(fullname);// here text         }
