WebRequest超时 [英] WebRequest Times out

问题描述

我有以下代码可读取正常运行的网页.第二次WebRequest超时时，两次调用相同的URL除外.
例如第一次使用http://www.yahoo.com/main.html可以正常工作
第二次http://www.yahoo.com/test.html它将超时.
有人知道如何解决这个问题吗?谢谢

for example first time http:www.yahoo.com/main.html will work fine

Anyone knows how to fix this? thanks

public static string ReadWebPage(string url)
        {
            string webPage;
            WebRequest request = WebRequest.Create(url);
            using (Stream stream = request.GetResponse().GetResponseStream())
            {
                StreamReader sr = new StreamReader(stream);
                webPage = sr.ReadToEnd();
                sr.Close();
            }
            return webPage;
        }

推荐答案

http://www.yahoo. com/test.html [ ^ ]

直接在浏览器中打开此页面时找不到该页面.它在yahoo的其他页面上将您重定向.因此，它无法处理两个请求.(一个页面导致另一页面加载)

祝您编程愉快！

http://www.yahoo.com/test.html[^]

this page is not found when open it directly in browser., it is redirecting you on something different yahoo''s page. so, it can''t process two requests.(one page is causing another page to load)

Happy coding!

使用垃圾回收处理导致问题的WebRequest对象.
在方法调用的末尾添加GC.Collect().

谢谢和问候，

Use garbage collection to dispose your WebRequest object which is causing issue.
Add GC.Collect() at end of your method call.
