I made a program that asks for input and returns a value. After, I want to ask if the user wants to continue. But I don't know what to use.

You want to use a do / while loop, or an infinite while loop with a conditional break.
Comments
A do-while loop is often used:
bool @continue = false;
do
{
//get value
@continue = //ask user if they want to continue
}while(@continue);
The loop will be executed once before the loop condition is evaluated.

This only allows 2 keys (Y and N):
ConsoleKeyInfo keyInfo;
do {
// do you work here
Console.WriteLine("Press Y to continue, N to abort");
do {
keyInfo = Console.ReadKey();
} while (keyInfo.Key != ConsoleKey.N || keyInfo.Key != ConsoleKey.Y);
} while (keyInfo.Key != ConsoleKey.N);

I would use a do..while loop:
bool shouldContinue;
do {
// get input
// do operation
// ask user to continue
if ( Console.ReadLine() == "y" ) {
shouldContinue = true;
}
} while (shouldContinue);

This one was the easiest to understand. Thanks.
You probably want a while loop here, something like:
bool doMore= true;
while(doMore) {
//Do work
//Prompt user, if they refuse, doMore=false;
}

use Do While Loop. something similar will work
int input=0;
do
{
System.Console.WriteLine(Calculate(input));
input = GetUserInput();
} while (input != null)

Technically speaking, any loop will do it, a for loop for example (which is another way to write a while(true){;} )
for (; true; )
{
//Do stuff
if (Console.ReadLine() == "quit")
{
break;
}
Console.WriteLine("I am doing stuff");
}
