C# MVC Saving multiple search strings for pagination

Question

I've seen examples on here for saving one string to pass onto the next page. But, I haven't been able to find or figure out how to save multiple search parameters without requiring a variable for each search string, which is something I'd rather not do, as I have 12 search fields.

I've seen examples with saving your variables to a viewbag and then passing that when you go to the next page. That works for the one variable, but not for multiple.

Is there a more eloquent solution then to have to pass individual view bags for each variable?

Thanks!

Why don't you pass an object in the viewbag with your said with variables as properties? ... Like a `Dictionary` key being search field, value being variable value. — interesting-name-here, Aug 11 '17 at 19:47
It seems to me that the information should be part of the ViewModel. — , Aug 11 '17 at 20:33

You can use a class for it like this:

public class SearchField
{
    public string Field1 { get; set; }
    public int Field2 { get; set; }
    // other fields
}

And save object to ViewBag like this:

SearchField objSearchField = new SearchField();
objSearchField.Field1="value1";
objSearchField.Field2 = 100;
// set other fields
ViewBag.SearchFields = objSearchField;

You can use viewbag or tempdata["stringid"]. tempdata might be a better choice here. What you will do is create an array of strings (or a list might be even better!) and store all your information in that array. Then you store it on tempdata. Something like this:

 string[] URLs = new string[12];
 //do stuff
 Tempdata["URLs"] = URLs;

When you get to the page you need the URLs in again, either in the controller or in the view you will write:

string[] URLS = (string[])Tempdata["URLs"];
//do stuff

or 

string[] URLS = Tempdata["URLs"] as string[];

Something like that should work. You should read up on the other ways to pass data in ASP MVC:
