问题描述

我有一个HTTPPPot其返回我捕捉使用：

I have a HTTPPPot whose return I capture using :

WebResponse webResponse = httpWebRequest.GetResponse();

Stream responseStream = webResponse.GetResponseStream();

StreamReader responseReader = new StreamReader(responseStream);

string responseString = responseReader.ReadToEnd();

在响应字符串，客户端返回以下

In the response string, the client returns the following

<input type="hidden" name="Location" value="sometext.txt"><input type="hidden" name="tableid" value="2"><input type="hidden" name="GroupID" value="1236781329">

根据以上情况，我需要得到每个表单元素的值。我不知道隐藏的表单元素的名称。是否有一个快速的方法来obatin这一点没有逐行读取整个响应线，确定该行包含我lookinng任何模式？

Based on the above, I need to obtain the values of each form element. I do know the names of the hidden form elements. Is there a quick way to obatin this without reading the entire response line by line and determining if the line contains any pattern that I am lookinng for?

推荐答案

我会用System.Xml.Linq的和解析响应到的XElement，并使用LINQ检索节点和属性的枚举列表。 LinqPad（ http://www.linqpad.net/ ）是一个伟大的工具来微调您的LINQ查询你把它粘贴到你的代码之前。

I would use System.Xml.Linq and parse the response into an XElement, and use LINQ to retrieve enumerated lists of nodes and attributes. LinqPad (http://www.linqpad.net/) is a great tool to fine-tune your LINQ queries before you paste it into your code.
