I have Url with space and would like to replace spaces with %20(escape them). UrlPathEncode should do that but it do not works on url below which has spaces. Can someone explain why it is not working?
System.Web.HttpUtility.UrlPathEncode("http://a1.quickcatchlabs.com/phototemplates/football_blimp_1.html?i_url=http://lh3.ggpht.com/yf5lVBB_WNBvBHT1HoIzY1SG0-PY5zRCobP3vBacuSk9N346F7CeAIRSFOltR6ZC1-yf-MNKAcAd7bAZ_A=s612-c&i_name=Patriots vs Redskins&i_venue_name=Gillette Stadium &i_venue_address=Foxborough , MA&d_Score_0=34&d_Score_1=27&d_Period_0=Final&p_name_0=Patriots &p_name_1=Redskins");

URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
According to the W3C (and they are the official source on these things), a space character in the query string (and in the query string only) may be encoded as either " %20 " or " + ".
Spaces are not allowed in URLs. They should be replaced by the string %20. In the query string part of the URL, %20 can be abbreviated using a plus sign (+).
Yes, the space is usually encoded to "%20" though. Any parameters that pass to a URL should be encoded, simply for safety reasons.
As the name implies, UrlPathEncode encodes the path. Just the path, not the query portion of the URL. If you add a space to path and run that code again, you will see that the space in the path portion is replaced by a %20, but the spaces in the query portion are not.
If you replace the call to UrlPathEncode with one to Uri.EscapeUriString, it will correctly encode the entire URL, not just the path.

You should call Uri.EscapeDataString.
