c# - Writing \t to a file from user input -

i have started learning c# , i'm experimenting file io. having problem writing tab (\t) character file.

this code far:

static void main(string[] args) {     string[] input = console.readline().split(' ');     console.writeline(string.join("\n", input));     file.writealllines(@"c:\users\shashank\desktop\test.txt", input);     console.readkey(); } 

when run script , input text:

hello \twhat \tis \tyour name 

the following gets written file:

hello \twhat \tis \tyour name 

but, want file output like:

hello             name 

i have looked online cannot find solution gives me desired result. tried using streamwriter no avail.

there method unescaping strings in .net, although perhaps not expect it:

regex.unescape(string)

console.writeline(regex.unescape(@"\thello\nworld")); 

will result in (depending on tab indentation setting):

    hello world 

so, if want unescape input string , split individual strings (lines) output, can this:

string[] input = regex.unescape( console.readline() ).split(' '); console.writeline(string.join("\n", input)); file.writealllines(@"c:\users\shashank\desktop\test.txt", input); console.readkey(); 

or, first split , unescape (using linq):

string[] input = console.readline().split(' ').select(regex.unescape).toarray(); console.writeline(string.join("\n", input)); file.writealllines(@"c:\users\shashank\desktop\test.txt", input); console.readkey(); 

if intention treat sequences of spaces single delimiter, use:

input.split(" ".tochararray(), stringsplitoptions.removeemptyentries)
