我看到google已重定向，我想摆脱多余的东西，只保留真实链接.我在google搜索引擎中输入了一个查询，我发现有这些真的很长的google重定向链接.我想发送真实的链接(减 扩展的重定向链接)，通过单击button1进入textbox1.text.

I see that google has redirect and I would like to get rid of the extra and only leave the real link. I type a query into the google search engine and I see that there are these really long google redirect links. I would like to send the real links (minus the extended redirect links) into a textbox1.text via a click of a button1.

我的问题是，使用Regex或String Splitt方法这样做会更好吗?无论哪种方式，有人都可以提供示例代码或代码段帮助吗?

My question is, is this better to do using Regex or a String Splitt method? Either way, could someone help with an example code or snippet?

我希望得到一个例子...

I would appreciate an example...

推荐答案

可能都不是... = P

Probably neither... =P

使用IndexOf()获取起始索引，该起始索引位于"url ="结束索引位于第一个&"在起始索引或行尾之后.

Use IndexOf() to get the start index at "url=" and the end index at the first "&" after the start index, or the end of line.

现在，您可以使用SubString()仅获取URL，然后使用System.Net.WebUtility.HttpDecode()替换编码令牌.

Now you can use SubString() to get just the URL and then System.Net.WebUtility.HttpDecode() to replace the encoding tokens.
