Check if user pressed Enter

Question

the following scenario is given:

Welcome screen appears. If user has read the welcome text he has 2 choices:

a) pressing ENTER to continue an getting the next text

b) pressing the E-Key in oder to leave the program

So my problem is:

how can I check if the user pressed the ENTER-Key?

what i tried so far - just as very primitive prototype

...var userInput= Console.ReadLine();

    if (userInput == "\r")
    {
        Console.WriteLine("correct");
    }
    else
    {
        Console.WriteLine("wrong");
    }....

I also tried it via Regex but I didn't make it run. Thanks for helping...

Look into using Console.ReadKey. It returns a ConsoleKey which you could then check if it is "Enter" — Carl Reid

Many thanks - I did try that as well. But I struggle with the part of identify the specific key "ENTER"... — Dr.Sun

Just like this (with Console.ReadKey):

static void Main(string[] args)
{
    Console.WriteLine("Hello Mr.Sun! Try press enter now:");
    var userInput = Console.ReadKey();
    if(userInput.Key == ConsoleKey.Enter)
    {
        Console.WriteLine("You pressed enter!");
    } else
    {
        Console.WriteLine("You pressed something else");
    }
}
