I have a simple c# question about how to grab a users input and store it into an Array

public void RunExercise()
{
int[] userIn = new int[9];
Console.WriteLine("User, please enter number 0 - 10");


}

This is what I have so far...

I just want it to ask the user to enter numbers 0-10
and then store them in the array
and then just sum up the numbers and print it out...
If anyone could help me that would be much appreciated
