Declare a persistent string array in C#

Question

Declare a persistent string array in c#. The string array to be put in a separate class.

Answer 1

Use a static field in a separate class so the array instance lives for the lifetime of the AppDomain.

public static class AppData
{
    // Persistent string array, accessible from anywhere in the app
    public static string[] Values = new string[10];
}

Usage:

// Read
string first = AppData.Values[0];

// Write
AppData.Values[0] = "Hello";

If the array size should not change, keep it as above. If the number of elements may change over time, consider using a List<string> instead of a fixed-size array.
