没有 HAP 的更新根据 wimh 的评论。只需将 &action=raw 作为查询字符串附加即可让您无需抓取即可完成这项工作。

using System;
using System.Net.Http;

public class Program
{
    private static HttpClient client = new HttpClient();

    public static void Main()
    {
        var response = client.GetAsync("https://en.wikipedia.org/w/index.php?title=Albatross&action=edit&action=raw").Result;
        var rawEditCode = response.Content.ReadAsStringAsync().Result;

        Console.WriteLine(rawEditCode);
    }
}

原始答案你可以使用 HtmlAgilitypack并简单地刮掉它:

using System;
using HtmlAgilityPack;

public class Program
{
    public static void Main()
    {
        HtmlWeb web = new HtmlWeb();
        HtmlDocument html = web.Load("https://en.wikipedia.org/w/index.php?title=Albatross&action=edit");

        var editorContent = html.DocumentNode.SelectSingleNode(@"//textarea[@id='wpTextbox1']").InnerHtml;
        Console.WriteLine(editorContent);
    }
}
