问题 Although the current Mono project's ServicePointManager class has the DnsRefreshTimeout property enabled into its interface. The related property isn't implemented. Sample call: ServicePointManager.DnsRefreshTimeout = 10*60*1000; // 10 minutes When running my application I get the next exception on runtime: The requested feature is not implemented. (System.NotImplementedException) at System.Net.ServicePointManager.set_DnsRefreshTimeout (Int32 value) [0x00000] in /Developer/MonoTouch/Source

问题 I can't find any proper description in the documentation for what this actually does. Does it check for the existence of A records or CNAME records or both? My understanding is that in .NET 4, this throws a SocketException if the host does not exist, and this is confirmed by my testing. 回答1: This is the list of addresses returned by var ips = System.Net.Dns.GetHostEntry("microsoft.com").AddressList; foreach (var ip in ips) Console.WriteLine(ip); // output 64.4.11.37 65.55.58.201 And these are

问题 I am trying to download some data from the reporting services instance on our TFS server. Given that the code should run on a computer that is not domain-joined, I figured that I would set the credentials myself. No luck, got a HTTP 401 Unauthorized back. Ok, so I hooked up Fiddler to see what was happening. But that's when I got Heisenberged - the call now went through without a hitch. So the authentication goes through with Fiddler connected, but fails without it. Is the Webclient broken or

问题 I want to POST multiple files and form variables to a CGI script, all in one HTTP request. I believe this requires a HTTP post with multipart/form-data encoding. Here is a sample HTML form that sends the required information; I need to send the same information through the application: <form action="/process.php" enctype="multipart/form-data" method="post"> <input type="text" name="foo" value="bar"> <input type="text" name="blah" value="baz"> <input type="file" name="file1"> <input type="file

问题 I'm using the .NET WebRequest while changing my HOSTS file. I'm observing that System.Net doesn't honor those changes - how can I make it do so? I have a number of servers load-balanced behind a single hostname, let's say 'example.com'. I want to target several of them individually, so my program will hard-code the machine-specific IP address in my HOSTS file before sending a request to example.com: 163.56.0.34 example.com For the first server and first request, this works fine. Then my
