You'd have to parse the script file and extract the values from the resulting state. And, .NET doesn't have such a parser built-in. "[Parse JavaScript code in C#](http://stackoverflow.com/questions/720678/parse-javascript-code-in-c-sharp)" may help with that. Though, if you have control over `db.js`, you could rewrite it as a JSON file. — Jonathan Lonowski, Apr 17 '14 at 16:13

Simple answer. You can't

There are some limits for server side coding and client side coding.

What you can do is send a JSON string to some generic handler and parse it from there.

You can not load JS file in C# in the format you want.

But you can do following way.

Instead of simple two array, use java script object which you can deserialize using JavaScriptSerilizer

If I have to do this I can do following way.

Create C# class with all property same name as I required in JS.
I fill those object and serialize this object using JavaScriptSerilizer so It give me one JSON format.

Next time whatever data I have I fill in JSON format so I can deserilize in C#.
