我正在尝试编写一个从本地Web服务器接收数据的弹性应用程序。读取数据的代码如下:
var myRequest =
(HttpWebRequest)
WebRequest.Create(
"http://"+_ipAddress+
"/FileBrowser/Download?Path=/DataLogs/DataLogSmall.csv&RAW");
myRequest.Referer = "http://"+_ipAddress+"/Portal/Portal.mwsl?PriNav=FileBrowser";
var myHttpWebResponse = (HttpWebResponse) myRequest.GetResponse();
// Display the contents of the page to the console.
Stream streamResponse = myHttpWebResponse.GetResponseStream();
此代码由try / catch块包围。如果在程序运行时拔掉路由器,则会引发以下错误:
System.Net.WebExceptionL The request was aborted: The operation has timed out.
这个有道理,我拔掉了路由器上的插头。
System.Net.WebException: Unable to connect to the remote server
拔出路由器时,上述错误仍在继续。
System.Data.Entity.Core.EntityException: The underlying provider failed on Open.
当路由器重新上线时会发生此(上面)错误。它通常发生一次或两次
System.Net.WebException: The operation has timed out
此错误会永远重复。
如果我停止并启动该程序,它将完美运行。 有什么想法吗?
