I am making a call to an external service using a web reference. The IP's are dynamic so I call them one by one, and everything works fine. Periodically some of the IP's won't be available and I am getting a timeout which I am handling. The issue is the length of time it takes to timeout is around 30 seconds for each call. I tried changing the timeout property on the ws to 5 seconds but it doesn't seem to make a difference. Can someone please help me with this?

从MSDN文档的 HttpWebRequest.Timeout 属性：

From the MSDN documentation of the HttpWebRequest.Timeout property:

一个域名系统（DNS）查询可能需要长达 15 秒返回或时间
OUT。如果您的请求包含需要解析主机名和你设置超时的值小于15秒，可能需要15秒以上引发WebException，表示你的请求超时之前。

A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.
