.net - Server.UrlEncode vs Uri.EscapeDataString

Question

What exactly is the difference between the two functions. The output seems similar except the Uri.EscapeUriString encodes spaces to %20 and Server.UrlEncode encodes them as a + sign.

And the final question which should be used preferably

Answer 1

If any one will came across this in the future:

After some digging I have found out that Uri.EscapeDataString is the preferable option. See the the highest voted answer here and this post.

EDIT: Adding the information from the second link here:

We found that in some cases you need to consider using Uri.EscapeDataString. In our case we are encrypting the querystring and found that UrlDecode is converting a plus (+) to space. This was causing us errors during decryption. Using Uri’s Escape and UnescapeDataString makes sense for us when constructing a custom querystring in the URL.
