Store data internally C# [closed]

Answer 1

If I understand your goal, you can use Settings to store data that will persist. Access the project properties and choose Settings. Click to create new settings file. You can add settings right there or you can do so programmatically:

static void Main(string[] args)
{
    //Assuming you added a string setting named "FooSetting" you can set it like this:
    Properties.Settings.Default.FooSetting = "Some Value...";
    Properties.Settings.Default.Save(); //you must call save or it won't persist

    //Read a value like this:
    Console.WriteLine(Properties.Settings.Default.FooSetting);

    Console.ReadKey();
}
