Convert IHtmlContent/TagBuilder to string in C#

public static string GetString(IHtmlContent content)
{
    using (var writer = new System.IO.StringWriter())
    {        
        content.WriteTo(writer, HtmlEncoder.Default);
        return writer.ToString();
    } 
}       

Answer 1

作为一个选项，您可以使用 html 解析器，例如 HtmlAgilityPack并获取一个 html 节点，然后创建一个 TagBuilder使用节点的名称、属性和内部 html:

public TagBuilder GetTagBuilder(string html)
{
    var node = HtmlAgilityPack.HtmlNode.CreateNode(html);
    var tagBuilder = new TagBuilder(node.Name);
    tagBuilder.MergeAttributes(node.Attributes.ToDictionary(x => x.Name, x => x.Value));
    tagBuilder.InnerHtml = node.InnerHtml;
    return tagBuilder;
}

例如:

var html = @"<div id=""div1"" class=""class1"">Something</div>";
var tagBuilder = GetTagBuilder(html);
var str = tagBuilder.ToString();

那么 str 的值将是:

<div class="class1" id="div1">Something</div>
