I want to read.txt file, extract every distinct from it and save it to array. So far I came up with this:
string text = File.ReadAllText(@"C:\Users\ASUS\Desktop\szyfrowanie\TextSample.txt");
string uniqueLetters = new string(text.Distinct().ToArray());
I couldn't find any way to save those distinct letters to a char array. Now I want to convert the uniqueLetters
array to a char
array. I've been trying through certain things like creating a new char[]
array and assigning uniqueLetter
value in a for
loop. ToCharArray()
also failed me. Does anybody have any ideas how to do it?
The return value type is char array and not string.
string text = "AABBCC";
var uniqueLetters = text.Distinct().ToArray();
Output (array of chars):
A, B, C.
Edit: Dont forget:
using System.Linq;
The ToArray
method returns a char[]
, that is, a char
array. Use it like this in your code:
string text = File.ReadAllText(@"C:\Users\ASUS\Desktop\szyfrowanie\TextSample.txt");
char[] uniqueLetters = text.Distinct().ToArray();
