WPF Application using a global variable

Question

I created a WPF application in c# with 3 different windows, Home.xaml, Name.xaml, Config.xaml. I want to declare a variable in Home.xaml.cs that I can use in both the other forms. I tried doing public string wt = ""; but that didn't work. How can I make it usable by all three forms?

Answer 1

You can use a static property:

public static class ConfigClass()
{
    public static int MyProperty { get; set; }
}

Edit:

The idea here is create a class that you holds all "common data", typically configurations. Of course, you can use any class but suggest you to use a static class. You can access this property like this:

Console.Write(ConfigClass.MyProperty)

Answer 2

There are two different things you can do here (among others; these are just the two that come to mind first).

1. You could make the variable static on Home.xaml.cs

   public static string Foo = "";

2. You could just pass in the variable to all three forms.

I would go with #2, myself, and if necessary create a separate class that contains the data I need. Then each class would have access to the data.
