Web service calling for Windows Phone 7 Network Programming

The following example shows the Windows Phone 7 app through a mobile phone number attribution query.ProgramHow to call the Web service interface.

Let's take a look at the running effect:

The app calls the following Web Service Interface for phone number attribution query:

Http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx

The first step is to add a reference to the WebService and add the web service. Then, a local proxy of the web service is generated.

Because. the net platform has built-in support for Web Services, including the construction and use of web services, therefore, in the Windows Phone 7 project, you can complete Web service development without other tools or sdks.

After a web service reference is added, the project's file directory is as follows:

Added the assumereference service and the servicereferences. clientconfig file.

Step 2 call Web Service

First Look At The XAML InterfaceCode

 <  Grid  X: Name  = "Contentpanel"  Grid. Row  = "1"  Margin  = "12, 0, 12, 0"  >  
  <  Textblock  Height  = "49" Horizontalalignment  = "Left"  Margin  ="  Name  = "Des"  Text  = "Enter the phone number you want to query"  Verticalalignment  = "TOP"  Width  = "284"     />  
  < Textbox  Height  = "72"  Horizontalalignment  = "Left"  Margin  = "6,106"  Name  = "No"  Text  = ""  Verticalalignment  = "TOP"  Width  = "415"     /> 
  <  Button  Content  = "Query"  Height  = "72"  Horizontalalignment  = "Left"  Margin  = "12,184"  Name  = "Search"  Verticalalignment  = "TOP"  Width = "160"  Click  = "Search_click"     />  
  <  Textblock  Height  = "211"  Horizontalalignment  = "Left"  Margin  = "6,277"  Name  = "Information" Text  = ""  Verticalalignment  = "TOP"  Width  = "444"     />  
  </  Grid  > 

The code for calling the Web Service is concise...

 Public     Partial    Class  Mainpage: phoneapplicationpage
{
  Public  Mainpage ()
{
Initializecomponent ();
}

  Private     Void  Search_click (  Object  Sender, routedeventargs E)
{
  //  Instantiate a Web Service proxy object  
 Mobilereference. mobilecodewssoapclient proxy  =     New  Mobilereference. mobilecodewssoapclient ();
  //  Events triggered after the call of the getmobilecodeinfo method ends  
  Proxy. getmobilecodeinfocompleted  + =  New  Eventhandler  <  Assumereference. getmobilecodeinfocompletedeventargs >  (Proxy_getmobilecodeinfocompleted );
  //  Add the call information, including method names and parameters, to the SOAP message and send it to the Web Service server over HTTP.
  //  The getmobilecodeinfo method of Web Service is called.  
  Proxy. getmobilecodeinfoasync (No. Text,  ""  );
}

  Void  Proxy_getmobilecodeinfocompleted (  Object Sender, assumereference. getmobilecodeinfocompletedeventargs E)
{
  If  (E. Error  =     Null  )
{
  //  Display returned results  
  Information. Text  =  E. result;
}
}
} 

OK ....
