在Frame.Navigate中使用可变页面类型

Question

Using WinRT, I am trying to implement navigation based on the users input. I tried to use a variable page type in the Navigate method. Unfortunately it doesn't look like it accepts variables as a page type. Does anybody know a way around this?

object myPage = page2;

this.Frame.Navigate(typeof(myPage));

I could just create switch statements and put the whole instruction in each statement but that seems ungainly and hard to maintain, especially since I may end up having a great deal of page types.

Any help would be appreciated. Thank you.

Edit: A little clarification. I am writing a quiz program that stores the quizzes in a List, however the are multiple types of quizzes that require specific page formats so I need different page types. I am storing the the Page type as a string in the List, and the list is randomized so I don't know the next page type from the current test. The quiz engine will pre read the next quiz in the queue and extract the page type and create a variable to insert into the this.Frame.Navigate command. This is where I am having the problem. Any ideas on how to get around this issue?

Thanks

There is no any "variable" type. var just allows you to write less code. Compiler substitutes return type of the expression as the variable type, there's no "magic".

You can write it like this:

object myPage;

if (???)
    myPage = new Page1();
else
    myPage = new Page2();

this.Frame.Navigate(myPage.GetType());

If you want to implement navigation based on the user's input, you definely need to use if or switch statement. You need to pass type of the page to Navigate() method. I don't really get what have you been trying to do with code above. I would do it by using simple if statement.
