Experience the new. Net Ajax brushless Technology

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 description for Methods.
///

public class DemoMethods
{

[Ajax.AjaxMethod]
public string GetCustomerMac(string clientIP) //para IP is the client's IP
{
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();
}
}
}

4. Write JavaScript and create a new file named default. The JS file is as follows:

function GetMac()
{
var clientIP="192.168.0.1";
document.getElementById("Mac").value=DemoMethods.GetCustomerMac(clientIP).value
alert(DemoMethods.GetCustomerMac(clientIP).value);
}

5. Put an HTML button on An ASPX page

Reference default. js on the page:

Add onclick = "javascript: getmac ()" to the onclick event of input ()"

Value = "Client IP" onclick = "javascript: getmac ();">

　　 6. Modify the application_start event of Global. asax and set the Ajax handlerpath:

Protected void application_start (Object sender, eventargs E)
{
Ajax. Utility. handlerpath = "ajax ";
}

Note that the. NET Ajax version must be manually added with Ajax. Utility. handlerpath = "ajax" in global. asax. The httphandler configuration information must be added to the web. config configuration file!
