这可能会帮助您在代码中包含以下内容以获取和发布数据：

public static string PostContent(this Uri url, string body, string contentType = null)
    {
        var request = WebRequest.Create(url);
        request.Method = "POST";

        if (!string.IsNullOrEmpty(contentType)) request.ContentType = contentType;

        using (var requestStream = request.GetRequestStream())
        {
            if (!string.IsNullOrEmpty(body)) using (var writer = new StreamWriter(requestStream)) { writer.Write(body); }

            using (var response = request.GetResponse() as HttpWebResponse)
            {
                using (var stream = response.GetResponseStream())
                using (var reader = new StreamReader(stream))
                {
                    return reader.ReadToEnd();
                }
            }
        }
    }

    public static string GetContent(this Uri url)
    {
        WebClient client = new WebClient();
        try
        {
            using (client)
            {
                client.Encoding = Encoding.UTF8;

                return client.DownloadString(url);
            }
        }
        catch (WebException)
        {
            return "";
        }
        finally
        {
            client.Dispose();
            client = null;
        }
    }

请注意，.aspx文件扩展名设计了服务器端页面，因此您只能下载在这些网站上导航时显示的html页面（{{1}也是如此） }文件）。

但是如果你想下载前端视图，这应该可行：

.php

下面的c＃代码不是从给定的网址读取网站或网页
