c# - Retrieving data from the operating system and storing it in the program -

if text file stored lots of words in cat, rat, hat, bat stored in words.txt, notepad how can retrieve each word separately , them stored in string array string [] myarray using filestream , streamreader object. has stored myarray[0] = "cat", myarray[1] = "rat".

assuming words separated spaces (i.e. no punctuation, etc.), can read file string , split it:

string alltext = file.readalltext("words.txt"); string[] myarray = alltext.split(     new [] {" ", environment.newline},     stringsplitoptions.removeemptyentries); 

if reason absolutely have use filestream , streamreader, you'd write:

string alltext = null; using (filestream fs = new filestream(...))  // fill in file name , other params {     using (streamreader sr = new streamreader(fs))     {         alltext = sr.readtoend();     } } // string split here 

now, if want take account punctuation , other special characters, that's more involved problem.
