C# Coding Trouble

Question

I am really stuck on how to do this:

 

Prompt a user to enter a zip code, and display a message indicating whether the zip code is in the company’s delivery area.

 

For example if the user enters a zip code in the array, such as 60007, the output should be Delivery to 60007 ok.

 

If the user enters a zip code not in the array, such as 60008, the output should be "Sorry - no delivery to 60008."

 

Here is what i have so far:

 

{

static void Main()

{

string[] zips = {"12789", "54012", "54481", "54982", "60007",

"60103", "60187", "60188", "71244", "90210"};

}

}
