推荐答案
我假设您尝试使用代码而不是浏览器来完成所有这些工作？
您必须将HTML加载到XMLReader。
通读XML找到表单元素和所有输入元素。
获取action表单元素的属性，因为这是您应该将表单发回的地址。
获取value和name来自每个输入元素的属性。
然后使用action和name，value对来构建一个新的WebRequest对象。
然后提交web请求。
I assume you're trying to do all of this with code and not a browser?
You have to load the HTML into anXMLReader.
Read through the XML to find theformelement and all theinputelements.
Get theactionattribute of the form element as this is the address to which you should post the form back to.
Get thevalueandnameattributes from each of the input elements.
Then use the action and name, value pairs to build up a new WebRequest object.
Then submit the web request.
