WCF Homestay (host) self-hosted (self-hosting) Simple instance "Windows Application Host"

Tag: ODI for Style project CLI cannot connect using proc task

Objective:

　　The host principle method of self-hosted by various applications is similar, therefore: here directly on the case!

Step one: Create service contracts and services

1. Create a new solution: Add a WCF Service library project.

2, in order to demonstrate, I have automatically generated the interface and the implementation of the interface class Delete, add a WCF Service myself

3, write the service function (at the same time, because the original auto-generated interface and class deleted, it is necessary to make the configuration file corresponding changes:)

Namespace Wcfself02
{
Note:you can use the ' Rename ' command on the ' Refactor ' menu to change the interface name ' ISERVICE02 ' in both code an d config file together.
[ServiceContract]
public interface IMe02
{
[OperationContract]
String ShowName (String str);
}
}
Namespace Wcfself02
{
Note:you can use the ' Rename ' command on the ' Refactor ' menu to change the class name ' Service02 ' in both Code and con Fig file together.
public class Me02:ime02
{

String Ime02.showname (String str)
{
String STRR;
STRR = str;
Console.WriteLine (STRR);
Return "La la la" + strr;
}
}
}

Step Two: Create a service Host

Create a Windows application to implement a self-hosted WCF service "Add a Windows application, introduce a wcfservice.library_01 reference, add a using System.ServiceModel; a library file reference. ", the specific implementation as well as the code is as follows:

Program.cs:

Using System;
Using System.Collections.Generic;
Using System.Diagnostics;
Using System.Linq;
Using System.Security.Principal;
Using System.Threading.Tasks;
Using System.Windows.Forms;

Namespace wcfhost02
{
Static Class Program
{
<summary>
The main entry point for the application.
</summary>

[STAThread]
static void Main ()
{
Application.enablevisualstyles ();
Application.setcompatibletextrenderingdefault (FALSE);

Switch (checkwindowsidentity ())
{
Case 0:application.run (New Form1 ()); Break
Case 1:application.exit (); Break
}

}

static int checkwindowsidentity ()
{
WindowsIdentity identity = WindowsIdentity.GetCurrent ();
WindowsPrincipal principal = new WindowsPrincipal (identity);
if (principal. IsInRole (windowsbuiltinrole.administrator)) return 0; Administrator

Normal user, start the program with the startup object to ensure that the startup object is created with administrator run
ProcessStartInfo startinfo = new ProcessStartInfo ();
Startinfo.useshellexecute = true;
Startinfo.workingdirectory = environment.currentdirectory;
Startinfo.filename = Application.executablepath;
Startinfo.verb = "RunAs";
Try
{
Process.Start (StartInfo);
return 1;//Normal User
}
Catch
{
return-1;//not authorized to run or user abandoned
}

}

}
}

Form1.cs:

Using System;
Using System.Collections.Generic;
Using System.ComponentModel;
Using System.Data;
Using System.Drawing;
Using System.Linq;
Using System.Net;
Using System.ServiceModel;
Using System.Text;
Using System.Threading.Tasks;
Using System.Windows.Forms;
Using Wcfself02;
Namespace wcfhost02
{
public partial class Form1:form
{
Me02 MM = new Me02 ();
ServiceHost host = null;
Public Form1 ()
{
InitializeComponent ();
}

private void Open_click (object sender, EventArgs e)
{
if (host==null)
{
Host = new ServiceHost (typeof (ME02));
Host. Open ();
}
}

private void Close_click (object sender, EventArgs e)
{
if (host!=null)
{
Host. Close ();
host = null;
}
}

private void Form1_Load (object sender, EventArgs e)
{
Close_click (sender, E);
}
}
}

Use the form of a configuration file to define endpoint additions and service behavior

App.config[one configuration method]:

<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name= "Metadatabehavior" >
<servicemetadata httpgetenabled= "true" Httpgeturl= "http://localhost:8733/Design_Time_Addresses/wcfself02/Me02 /metadata "/>
</behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorconfiguration= "Metadatabehavior" name = "wcfself02. Me02 ">
<endpoint address= "http://localhost:8733/Design_Time_Addresses/wcfself02/Me02/"
Binding= "Wshttpbinding"
Contract= "WCFSELF02. IMe02 "/>
</service>
</services>
</system.serviceModel>
</configuration>

Compile the host program, open the banner. exe file as an administrator at the location of the file, and click "Open" to enter the address in the configuration file (http://localhost:8733/Design_Time_Addresses/wcfself02/Me02 /metadata), open, click "Close", unable to connect, instructions to create success!!

App.config[one of the first configuration methods]:

<?xml version= "1.0" encoding= "Utf-8"?>
<configuration>

<appSettings>
<add key= "Aspnet:usetaskfriendlysynchronizationcontext" value= "true"/>
</appSettings>
<system.web>
<compilation debug= "true"/>
</system.web>
<!--when deploying the Service library project, the content of the config file must is added to the host ' s
App. Config file. System.Configuration does not the support config files for libraries. -
<system.serviceModel>
<services>
<service name= "wcfself02. Me02 ">
<endpoint address= "" binding= "BasicHttpBinding" contract= "wcfself02. IMe02 ">
<identity>
<dns value= "localhost"/>
</identity>
</endpoint>
<endpoint address= "Mex" binding= "mexHttpBinding" contract= "IMetadataExchange"/>
<baseAddresses>
<add baseaddress= "http://localhost:8733/Design_Time_Addresses/wcfself02/Me02/"/>
</baseAddresses>
</service>
<service name= "wcfself02. Me02 ">
<endpoint address= "" binding= "BasicHttpBinding" contract= "wcfself02. IMe02 ">
<identity>
<dns value= "localhost"/>
</identity>
</endpoint>
<endpoint address= "Mex" binding= "mexHttpBinding" contract= "IMetadataExchange"/>
<baseAddresses>
<add baseaddress= "http://localhost:8733/Design_Time_Addresses/wcfself02/Me02/"/>
</baseAddresses>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!--to avoid disclosing metadata information,
Set the values below to false before deployment--
<servicemetadata httpgetenabled= "true" httpsgetenabled= "true"/>
<!--to receive exception details on faults for debugging purposes,
Set the value below to true. Set to False before deployment
To avoid disclosing exception information--
<servicedebug includeexceptiondetailinfaults= "False"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

</configuration>

Compile the host program, open the banner. exe file as an administrator at the location of the file, and click "Open" to enter the address in the configuration file (http://localhost:8733/Design_Time_Addresses/wcfself02/Me02 /), open, click "Close", unable to connect, instructions to create success!!

Special attention!! When running the host application, be sure to run the host application with Administrator privileges!!!

Step three: Create a client (reference service, verify the services created above)

Create a console application that references the above services as a client, and when adding service apps, be aware that the service is turned on!!!

Reference the function of the service side, can realize the corresponding function, here not more than repeat!
