WebResponse 对象的方法 Close() 当由子类重写时，将关闭响应流。 CreateObjRef(Type) 创建一个对象，该对象包含生成用于与远程对象进行通信的代理所需的全部相关信息。...(Inherited from MarshalByRefObject) Dispose() 释放 WebResponse 对象使用的非托管资源。...Dispose(Boolean) 释放由 WebResponse 对象使用的非托管资源，并可根据需要释放托管资源。 Equals(Object) 确定指定的对象是否等于当前对象。...GetResponseStream() 当在子类中重写时，从 Internet 资源返回数据流。 GetType() 获取当前实例的 Type。...(Inherited from Object) --------------------------- 推荐一位其他人的文章，里面列出了WebRequest、WebResponse 等对象所有的方法、

例如，当您从响应很慢的API服务器下载大文件时，您的应用程序的UI不会停止响应。 HttpWebRequest通常和WebResponse一起使用，一个发送请求，一个获取数据。...HttpWebRequest http = (HttpWebRequest)WebRequest.Create("http://example.com"); WebResponse response =...(data, 0, data.Length); HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse...webRequest.Timeout = timeout; WebResponse webResponse = webRequest.GetResponse();...= new WebClient()) { webClient.DownloadFile("http://example.com", "路径"); } WebClient主要面向了WEB网页场景，在模拟

HttpWebRequest的作用： HttpWebRequest对HTTP协议进行了完整的封装，对HTTP协议中的 Header, Content, Cookie 都做了属性和方法的支持，很容易就能编写出一个模拟浏览器自动登录的程序...hl=zh-CN” ); req.Method = “GET”; using (WebResponse wr = req.GetResponse()) { //在这里对接收到的页面内容进行处理.../WebResponse /// /// 通过 WebRequest/WebResponse 类访问远程地址并返回结果，需要Basic认证； ///...request = WebRequest.Create(new Uri(uri)); if (!...); getStream = webResponse.GetResponseStream(); contentLength = webResponse.ContentLength

参看了MVP的利用WebClient和WebRequest类获得网页源代码于是想自己动手写点，当然是参考其的办法啦。...按照上面的文章编写了代码， 我的btn函数如下 string urlPage = “”; urlPage = UrlText.Text; WebRequest...request = WebRequest.Create(urlPage); WebResponse response = request.GetResponse();...，就是采用Server.HtmlEncode这个方法 我改动如下 string urlPage = “”; urlPage = UrlText.Text; WebRequest...request = WebRequest.Create(urlPage); WebResponse response = request.GetResponse();

那么怎么用C#来模拟一个用户的登录拉？要实现用户的登录，那么首先就必须要了解一般网站中是怎么判断用户是否登录的。...要写这种面向协议的网络程序，抓包工具是少不了的，我们首先是要使用抓包工具分析在普通浏览器中登录时发送和接收的内容才好进一步使用C#来模拟浏览器发包。...在面向HTTP协议上，C#中有WebRequest、WebResponse、HttpWebRequest和HttpWebResponse等类。...Cookie、PostData的情况下要获得一个页面的HTML的方法很简单： public static string GetHtml(string URL) { WebRequest...; WebResponse wrp; wrp = wrt.GetResponse(); return new StreamReader
