c# - Using ternary operator on Console.WriteLine

I need to print some string based on the true or false of a condition.

For example:

if(i == m) {
Console.WriteLine("Number is valid");
} else {
Console.WriteLine("Number is invalid");
}

How can I check this condition and print a message using conditional operator and with only one Console.WriteLine?

I was trying:

(i == m) ? Console.WriteLine("Number is valid") : Console.WriteLine("Number is not valid");

I know I'm doing it wrong here. Can someone please tell me the correct way?

Try this:

Console.WriteLine("Number is " + ((i == m) ? "valid" : "not valid"));
