Question

I have almost 200,000 html pages and I need to figure out the height and width at which each html will render in any browser. I only need approximate numbers. How I can programmatically do this with C#?

Answer 1

C# Does not execute inside of a browser, and should not be used to try and determine the width and height a given HTML page will render at in a browser. Moreover, there is no answer for “any browser”, as different browsers may support different fonts, may render the same content slightly different, and may be configured with different display-related settings (most browsers allow the user to arbitrarily scale the default font size up or down as desired, which would of course impact the final render size).

In general, however, I would suggest you do something like:

1. Come up with a JavaScript snippet that can compute the current size of the document.
2. Write a C# (or Java, C, bash, etc.) program to append your snippet to each of your 200,000 pages.
3. Use a browser-based test-harness like Selenium or Webdriver to load up each of your 200,000 pages, extract the result from your JavaScript snippet, and log it out to somewhere convenient.
4. Optionally, you can repeat step 3 with different browsers to get the width/height for all the different browsers that you care about.

Edit: Apparently Webdriver and Selenium are the same thing now. When did that happen?
