Question

I need to know if there are any input symbols in the standard input.

But I don’t know how to check such a condition.

As I understand I can’t use Console.Read() because it will actually read the next input symbol.

I think you could use Console.In as an System.IO.TextReader and use the Peek()-Method:

if(Console.In.Peek() == "I don't know what it will be...")
{ /* Do something */ }
