Passing values between C# classes

I'm quite new in the wonderful world of C# and I'm not sure how to cope with such a problem.

I have a .NET website on Visual Studio 2008, and I have a main page, main.aspx (with its following main.aspx.cs) and a game page, game.aspx (also with game.aspx.cs).

In the main class in main.aspx.cs I have a static variable, private static string _username; and with it, a method called getUsername that simply returns this value.

Now in my game class (game.aspx.cs) I have an event handler, saveButton_Click(), and in this function I need the value of _username!

If it helps, a user starts on the main page, and then logs in... the variable _username is saved if the login is valid and then the user clicks a link to go to the game.aspx page!

I've looked into the internal keyword, but I am not sure how to use it in this particular example or even if it's the right thing to do in this example!

IMHO, you could use Forms Based Authentication which would then make it very simple to get the user name, via User.Identity.Name.

You have to use Sessions to store and access the value in multiple pages:

//To store value in session variable
Session["UserName"] = "UserName"; 

//To access the value in the session variable
String UserName = Session["UserName"];

Check for Details ASP.NET Session State

Add this to your main page and game page classes:

protected string UserName {
    get { 
        string retVal=string.Empty;
        if (!string.IsNullOrEmpty(Session["UserName"]))
            retVal=Session["Username"].ToString();
        return retVal;
    }
    set{
        Session["UserName"]=value;
    }
}

and then access the property from your code;

To answer your question, you can make a public static property in a separate class.

However, don't.

This model will fail horribly (or worse) when two people use your site at once.

Instead, you should use Session State.
