[Remoting series] 12: Configuration File

Replacing hard encoding with configuration files can make applications more flexible. Especially for distributed systems, this means that we can easily adjust the configuration of distributed objects. The remoting configuration file is relatively simple. For details, refer to msdn.

The following is a simple example, including Sao / Configuration example of Cao.

Server. CS
Binaryclientformattersinkprovider cbin =   New Binaryclientformattersinkprovider ();
Binaryserverformattersinkprovider sbin =   New Binaryserverformattersinkprovider ();
Sbin. typefilterlevel = Typefilterlevel. Full;

Hashtable Properties =   New Hashtable ();
Properties [ " Port " ] =   801 ;

Tcpchannel Channel =   New Tcpchannel (properties, cbin, sbin );
Channelservices. registerchannel (channel, False );

Remotingconfiguration. registerwellknownservicetype ( Typeof (Data ), " Data " , Wellknownobjectmode. Singleton );
Remotingconfiguration. applicationname =   " Test " ;
Remotingconfiguration. registeractivatedservicetype ( Typeof (Data2 ));

Client. CS
Tcpchannel Channel =   New Tcpchannel ();
Channelservices. registerchannel (channel, False );
Remotingconfiguration. registerwellknownclienttype ( Typeof (Data ), " TCP: // localhost: 801/Data " );
Remotingconfiguration. registeractivatedclienttype ( Typeof (Data2 ), " TCP: // localhost: 801/test " );

Data data =   New Data ();
Data. Test ();

Data2 data2 =   New Data2 ();
Data2.test ();

Change to the corresponding configuration file.

Server. config
<? XML version = " 1.0 " Encoding = " UTF-8 "   ?>
< Configuration >
< System. runtime. remoting >
< Application name = " Test " >
< Channels >
< Channel Ref = " TCP " Port = " 801 " >
< Clientproviders >
< Formatter Ref = " Binary " />
</ Clientproviders >
< Serverproviders >
< Formatter Ref = " Binary " Typefilterlevel = " Full "   />
</ Serverproviders >
</ Channel >
</ Channels >
< Service >
< Wellknown Mode = " Singleton " Type = " Learn. Library. remoting. Data, learn. Library " Objecturi = " Data "   />
< Activated type = " Learn. Library. remoting. data2, learn. Library "   />
</ Service >
</ Application >
</ System. runtime. remoting >
</ Configuration >

Client. config
<? XML version = " 1.0 " Encoding = " UTF-8 "   ?>
< Configuration >
< System. runtime. remoting >
< Application >
< Channels >

< Activated type = " Learn. Library. remoting. data2, learn. Library "   />
</ Client >
</ Application >
</ System. runtime. remoting >
</ Configuration >

Server. CS
Remotingconfiguration. Configure ( " Server. config " , False );

Client. CS
Remotingconfiguration. Configure ( " Client. config " , False );

Data data =   New Data ();
Data. Test ();

Data2 data2 =   New Data2 ();
Data2.test ();
