Windows Phone 7 network programming call WCF Service

I. Introduction to WCF Service

Windows Communication Foundation is a distributed communication programming framework provided by Microsoft to build service-oriented applications, developers can build cross-platform, secure, reliable, and enterprise-level interconnected application solutions that support transaction processing. Microsoft integrated Microsoft Distributed applicationsProgramMany mature technologies in development, such as enterprise Sevices (COM +),. Net remoting, and Web
Service (asmx), WSE, and MSMQ message queues.

Communication scope: Cross-process, cross-machine, cross-subnet, enterprise network, or Internet;

HOST: It can be ASP. NET (IIS or was), EXE, WPF, Windows Forms, NT Service, COM +;

Communication Protocol: TCP, HTTP, cross-process, and custom.

Ii. Create a WCF Service

The following shows how to set up a WCF Service and output a string.

Step 1: Open Visual Studio 2010 to create a WCF Service Application.

 
Step 2: Modify the service1.svc and iservice1.cs files.

The default file directory of the created project is as follows:

Add a method to service1.svc

Public String hellowcf ()
{
Return "Hello WCF ";

}

Add an interface to iservice1.cs:

[Operationcontract]
String hellowcf ();

Step 3: create a virtual directory of the website pointing to the project of WCF.

Find the Internet information manager in the control panel and open it. Create a virtual directory under the default web site node and name it WCF. The path points to the Web application in this example.CodeAnd click OK.

3. Call the WCF Service

Step 1: Add a reference to the WCF Service in the Windows Phone project to generate a proxy.

A servicereferences. clientconfig file is generated after the reference is successful. The file is as follows:

<Configuration>

<System. servicemodel>

<Bindings>

<Basichttpbinding>

<Binding
Name = "basichttpbinding_iservice1"
Maxbuffersize = "2147483647"

Maxcompute edmessagesize = "2147483647">

<Security
Mode = "NONE"/>

</Binding>

</Basichttpbinding>

</Bindings>
<Client>

<! -- Http: // localhost/WCF/service1.svc refers to the address of the WCF Service -->
<Endpoint address = "http: // localhost/WCF/service1.svc"
Binding = "basichttpbinding"
Bindingconfiguration = "basichttpbinding_iservice1"
Contract = "wcfservice. iservice1"
Name = "basichttpbinding_iservice1"/>
</Client>
</System. servicemodel>

</Configuration>

Step 2: Call the WCF Service.
Wcfdemo. wcfservice. service1client proxy = new wcfservice. service1client ();
Proxy. hellowcfcompleted + = new eventhandler <wcfservice. hellowcfcompletedeventargs> (proxy_hellowcfcompleted );
Proxy. hellowcfasync ();

 
Void proxy_hellowcfcompleted (Object sender,
Wcfservice. hellowcfcompletedeventargs E)
{
Textblock1.text = E. Result. tostring ();
}

XAML code

<Grid X: Name = "contentpanel" grid. Row = "1"
Margin = "12, 0, 12
<Textblock
Height = "63" horizontalalignment = "left"
Margin = "60, 47," name = "textblock1" text = ""
Verticalalignment = "TOP" width = "249"/>
</GRID>

Running effect:
