Experience the surprise of the new. net Ajax refreshing Technology

Today, I got a. net Ajax development kit, which includes ASP2.0 and Ajax currently used in ASP1.1. For more information, see http://ajax.schwarz-interactive.de.

1. Create a new project and add reference Ajax. dll to the reference. Ajax. dll is located in the downloaded package.

2. Create HttpHandler and add it to web. config.

<Configuration> <System. web> <HttpHandlers> <Add verb = "POST, GET" path = "ajax/*. ashx" type = "Ajax. PageHandlerFactory, Ajax"/> </HttpHandlers> <System. web> </Configuration>

3. Create a new class DemoMethods, which can obtain the client MAC address:

Using System; Using System. Web; Namespace AjaxSample { /** // <Summary> /// Summary description for Methods. /// </Summary> Public class DemoMethods { [Ajax. AjaxMethod] Public string GetCustomerMac (string clientIP) // enter the Client IP address here. This function is used for testing. You can also write other simple functions instead. { String mac = ""; System. Diagnostics. Process process = new System. Diagnostics. Process (); Process. StartInfo. FileName = "nbtstat "; Process. StartInfo. Arguments = "-a" + clientIP; Process. StartInfo. UseShellExecute = false; Process. StartInfo. CreateNoWindow = true; Process. StartInfo. RedirectStandardOutput = true; Process. Start (); String output = process. StandardOutput. ReadToEnd (); Int length = output. IndexOf ("MAC Address = "); If (length> 0) { Mac = output. Substring (length + 14, 17 ); } Process. WaitForExit (); Return mac. Replace ("-", ""). Trim (); } } }
