HtmlDocument.Save (HtmlAgilityPack) 输出不完整的文档

Question

我们正在使用HtmlAgilityPack保存HTML ...输出正在被修剪，不明白为什么。

我们用来创建导出的代码：

var doc = new HtmlDocument();

string html = "<head>";

html += "<title>Page Title</title>";      
html += "<style>" + style + "</style>";
html += "</head><body>";
html += body; // string is not very long
html += "<script>" + js + "</script>";   
html += "</body>";

FileStream sw = new FileStream(html_file, FileMode.Create);
doc.LoadHtml(html);
doc.Save(sw);
sw.Close();

导出的文件 body 被修剪。我们做错了什么？

完整的字符串非常小而且直接，它不包含脚本、特殊字符、none 之类的......导出在 "Additional Charges" 标题的中间被修剪标题后的第二部分...

<div class="page-body">
                    <div class="top-title">1.Bill Summary <small style="font-size:14px;">1/2</small></div>
                    <div class="title" string="Device">

不确定您使用的是哪个版本的 .NET/HtmlAgilityPack。我能够在 .NET 4.0/HtmlAgilityPack 1.3.0.0 上重现它，但不确定这些版本是否正确。

无论如何，创建 StreamWriter 而不将 AutoFlush 设置为 true 似乎是某种 HtmlAgilityPack 错误。因此它关闭流写入器而不刷新它。

好消息是您可以自己传递 StreamWriter 而不是 Stream。

你的代码根据我得到的结果进行了调整：

var doc = new HtmlDocument();

string html = "<head>";

html += "<title>Page Title</title>";      
html += "<style>" + style + "</style>";
html += "</head><body>";
html += body; // string is not very long
html += "<script>" + js + "</script>";   
html += "</body>";

doc.LoadHtml(html);
using(FileStream fs = new FileStream(html_file, FileMode.Create))
using (StreamWriter sw = new StreamWriter(fs, Encoding.UTF8) { AutoFlush = true }) {
    doc.Save(sw);
    // You don't need to Close the stream by yourself, Dispose() will do the work
    // sw.Close();
}

请注意，我无法在最新版本的 .NET/HtmlAgilityPack.
