YouTube Data API – Google Code
What is the YouTube Data API?
The YouTube Data API offers a simple and powerful way to access YouTube’s content in the form of Google Data API feeds. Your client application can request a list of videos that match specific search criteria, get access to the most popular YouTube videos, or get public information about YouTube users (such as playlists, subscriptions, or contacts).
The YouTube Data API is based on the Atom 1.0 and RSS 2.0 syndication formats and the Atom Publishing Protocol. Learn more about Google Data APIs.

Thanks for this information
i am new to Youtube API and going through the Youtube Developer’s
Guide to run the test application:
i just follow the guide about always some problems came out:
For instance::
i am using this code in aspx.cs file
static void printVideoFeed(YouTubeFeed feed)
{
foreach (YouTubeEntry entry in feed.Entries)
{
printVideoEntry(entry);
}
}
static void printVideoEntry( Video video)
{
….. just copy from the .net guide..
}
But the VS 2008 always says
Error 4 Argument ’1′: cannot convert from
‘Google.GData.Client.Feed’ to
‘Google.GData.YouTube.YouTubeFeed’.
However, how to change the YoutubeEntry to Video?!. Here.?
Any suggestion. thx in advanced..
