Do While String Question

Question

This is not working for some reason.
Please help!

//Do loop to make sure input is 1, 2 or 3 only
do
{

//Opening input question.
Console.WriteLine("Type a number: rock(1) paper(2) or scissors(3)");

//Sets string variable based on user input
choice = Convert.ToString(Console.ReadLine());

} while (choice != "1" || choice != "2" || choice != "3");

Console.WriteLine("shipoopy");

Answer 1

choice is not initialized. Write it as:
string choice = Console.ReadLine();
ReadLine() always returns a string, so no need to convert.

Use && instead of || for the condition, otherwise you'll stay in the loop even with the right input.

Answer 2

You didn't even set something :

int choice = 0;

Place it before the while loop.
In the while loop :
choice = Console.ReadLine();

Answer 3

I had already declared the CHOICE variable. Using && instead of || made it work!
