Question

我使用DownloadString类中的WebClient从页面中读取内容，然后使用StreamWriter类将其内容写入静态HTML文件。在我正在阅读的页面上，有一个内联的javascript方法，只需设置一个锚元素的OnClick属性来设置window.location = history.go(-1);我就可以了当我查看静态HTML页面时，会看到一个奇怪的字母，显示在动态网页上不会出现。

WebClient＆amp; SteamWriter代码

    using (var client = new WebClient())
        {
            var html = client.DownloadString(url);

            //This constructor prepares a StreamWriter (UTF-8) to write to the specified file or will create it if it doesn't already exist
            using (var stream = new StreamWriter(file, false, Encoding.UTF8))
            {
                stream.Write(html);
                stream.Close();
            }
        }

动态网页的HTML代码段

<span>Sorry, but something went wrong on our end. &nbsp;Click <a href="#" onclick="window.location.href = history.go(-1);">here</a> to go back to the previous page.</span>

静态网页的HTML代码段

<span>Sorry, but something went wrong on our end. Â&nbsp;Click <a href="#" onclick="window.location.href = history.go(-1);">here</a> to go back to the previous page.</span>

我在想添加Encoding.UTF8参数可以解决这个问题，但它似乎没有帮助。我需要做某种额外的编码或解码吗？或者我是否完全错过了此类操作所需的其他内容？

我更新了WebClient以在UTF8中进行编码，因为它将资源转换为字符串，似乎已经解决了这个问题。

            using (var client = new WebClient())
            {
                client.Encoding = System.Text.Encoding.UTF8;
                var html = client.DownloadString(url);

                //This constructor prepares a StreamWriter (UTF-8) to write to the specified file or will create it if it doesn't already exist
                using (var stream = new StreamWriter(file, false, Encoding.UTF8))
                {
                    stream.Write(html);
                    stream.Close();
                }
            }
