Configuring WCF Services in Code WCF 4.5

Question

User-1716690740 posted

Hi am trying to configure wcf using code below is the code 

public static void Configure(ServiceConfiguration config)
{
string configPath=ConfigurationManager.AppSettings["wcfconfigDBPath"];

// Enable “Add Service Reference” support
config.Description.Behaviors.Add(new ServiceMetadataBehavior { HttpGetEnabled = true });
// set up support for http, https, net.tcp, net.pipe
if (isEnabled(configPath, "enablehttp"))
config.EnableProtocol(new BasicHttpBinding());
if (isEnabled(configPath, "enablenettcp"))
config.EnableProtocol(new NetTcpBinding());
if (isEnabled(configPath, "enablepipe"))
config.EnableProtocol(new NetNamedPipeBinding());
// add an extra BasicHttpBinding endpoint at http:///basic
//config.AddServiceEndpoint(typeof(IService), new BasicHttpBinding(), "basic");

}

private static bool isEnabled(string path,string elementName)
{
try
{
string elementValue = string.Empty;
bool returnVal = false;
using (XmlTextReader reader = new XmlTextReader(path))
{

reader.ReadToFollowing(elementName);
if(reader.Read())
elementValue = reader.Value;

}
if (!string.IsNullOrEmpty(elementValue))
{
bool.TryParse(elementValue, out returnVal);
}
return returnVal;

}
catch(Exception ex)
{
return false;
}
}

Am trying the enable/disable protocol using a XMl file ; Am not sure when "static void Configure" gets fired ; Is there any way to do it ?

Hi,

>>Am not sure when "static void Configure" gets fired . Is there any way to do it?

You can put the method static void Configure in service like below:

public class Service1 : IService1
{

public static void Configure(ServiceConfiguration config)
 {
 string configPath=ConfigurationManager.AppSettings["wcfconfigDBPath"];

 // Enable “Add Service Reference” support
 config.Description.Behaviors.Add(new ServiceMetadataBehavior { HttpGetEnabled = true });
 // set up support for http, https, net.tcp, net.pipe
 if (isEnabled(configPath, "enablehttp"))
 config.EnableProtocol(new BasicHttpBinding());
 if (isEnabled(configPath, "enablenettcp"))
 config.EnableProtocol(new NetTcpBinding());
 if (isEnabled(configPath, "enablepipe"))
 config.EnableProtocol(new NetNamedPipeBinding());
 // add an extra BasicHttpBinding endpoint at http:///basic
 //config.AddServiceEndpoint(typeof(IService), new BasicHttpBinding(), "basic");

 }
}

Amy , Thanks for the link and info. I dont see a problem in making that code work.

My question is there any way to enable/disable protocol beased on DB/xml configuration without bringing down the service

You can use the code Amy send us and have a bit field in your database.

For Example -

If that bit field is 0 means disable the protocol. 

You can read the value from db or xml and then depends on value put your logic to enable/disable.
