Client Agent Analysis

Client Agent Analysis
• Each Service class corresponds to a proxy class on the client.
• Each proxy class is a subclass of the SYS. net. webserviceproxy class.
• Each method of the proxy class corresponds to a static method of the class
• Finally, the request is sent by the SYS. net. webserviceproxy. Invoke method.

Aspx < Form ID = " Form1 " Runat = " Server " >
< ASP: scriptmanager ID = " Scriptmanager1 " Runat = " Server " Scriptmode = " Debug "   />

< Input type = " Button " Value = " Get range random " Onclick = " Getrandom (1, 50,100) "   />

< Script Language = " Javascript " Type = " Text/JavaScript " >
Function getrandom (minvalue, maxvalue)
{
SYS. net. webserviceproxy. Invoke (
" Services/usehttpgetservice. asmx " ,
" Getrangerandom " ,

" Maxvalue " : Maxvalue },

}

Function onsucceeded (result)

The inlinescript = "true" of scriptmanager is not called by using the SYS. net. webserviceproxy. Invoke method instead of the client proxy.
