我有一个很大的 url，我正在使用 System.Web.HttpUtility.UrlEncode 进行编码。当我对其进行编码时，它不像我拥有的​​工作示例那样对其进行编码。我不确定问题是什么，可能是不同的字符类型或其他东西，我举了一个例子来说明应该创建的内容和实际创建的内容。感谢您的帮助，我迷路了。

工作示例（看看这个有 Did%252Citag%252 而另一个没有）

看起来在第一个示例中，URL 是双重编码的。这意味着如果您查看解码的 sparams 参数，它表示为

sparams=id%2Citag%2Csource%2Cip%2Cipbits%2Cexpire

在你的第二个例子中

sparams=id、itag、来源、ip、ipbits、过期

因此，第一个示例中发生的情况是，他们首先对值执行 UrlEncode。使用此值构造 URL，然后对构造的 URL 执行 UrlEncode。

更新：如果您的查询字符串的值包含需要进行 UrlEncoded 的值（例如，& 空格？等），这是要遵循的一般做法

根据w3c标准，您的示例很好。没有 %252 符号。

我不确定您到底在期待什么，但是当您将这些字符串发送到URL Decoder时，您会得到以下结果：

你的 URLS 完全不同，而且它们还有一个我不确定你想要的前导字符。
