如何从中获取实际URL。我尝试了HttpUtility.UrlDecode和其他各种实用方法。但似乎什么都不起作用。有人能告诉我什么是%253A和其他字符吗。它看起来是Unicode，但我如何从中获得URL，它实际上可以粘贴在浏览器中？

如何从中获取可以粘贴到浏览器中的URL

它是双重编码的。

尝试

Console.Write(HttpUtility.UrlDecode(HttpUtility.UrlDecode(@"http%253A%252F%252Fo-o.preferred.bom03s03.v18.lscache5.c.youtube.com%252Fvideoplayback%253Fsparams%253Dalgorithm%25252Cburst%25252Ccp%25252Cfactor%25252Cid%25252Cip%25252Cipbits%25252Citag%25252Csource%25252Cexpire%2526fexp%253D906717%25252C903945%25252C912602%25252C913601%25252C901601%2526algorithm%253Dthrottle-factor%2526itag%253D34%2526ip%253D59.0.0.0%2526burst%253D40%2526sver%253D3%2526signature%253D904B7C772910BF285A6068BC1B5F5BB326A15A67.A0A3B85945C69A12B590D3D61695A3095039728D%2526source%253Dyoutube%2526expire%253D1331814444%2526key%253Dyt1%2526ipbits%253D8%2526factor%253D1.25%2526cp%253DU0hSRlhMUl9JTkNOMl9QRlZFOkVoSFJkckpoeHMw%2526id%253D4749aebe2c52addd")));
