c# - Flushing System.Console.Read()

I'm learning C# for one of my classes and for my assignment I need to get user input from the console.

In my program I have:

choice = (char)System.Console.Read();

Later on in the program I use

if (System.Console.ReadLine() == "y")

to get input from the user.

The second statement gets skipped when I run the program. I'm guessing that the System.Console.Read() is leaving a newline in the stream. In C/C++, there's fflush() and cin.ignore(). What is the equivalent function in C#?

I know that it's probably easier for me to use ReadLine() or ReadKey(), but I'm just curious as to how to use Read() with newlines

This is my equivalent for fflush:

while (Console.KeyAvailable)
    Console.ReadKey(true);
