Many people have been asking me how to manage publishing point programmatically on IIS Media Services 3.0 (instead of the 2.0 bits, as I explained in this post)

So, I started to dig and I came up with the following code:

// Live Streaming Section Path
const string LiveStreamingSectionPath = "system.webServer/media/liveStreaming";

// Change this settings with your values

// Site name
string siteName = "Default Web Site";
// Application name
string applicationName = "/SmoothStreaming";
// Publishing point filename
string fileName = "LiveSmooth.isml";

ServerManager serverManager = new ServerManager();

// Gets the site from IIS
Site site = serverManager.Sites[siteName];

// Gets the application from IIS
Application application = site.Applications[applicationName];

// Gets the LiveStreamingSection from the site configuration
ConfigurationSection section = site.GetWebConfiguration().GetSection(LiveStreamingSectionPath);

// Gets the ConfigurationMethodInstance to get the available publishing points
ConfigurationMethodInstance instance = section.Methods["GetPublishingPoints"].CreateInstance();

// Sets the input parameters of the GetPublishingPoints method
instance.Input["siteName"] = site.Name;
instance.Input["virtualPath"] = applicationName;

// Executes the method
instance.Execute();

// Gets the PublishingPointCollection associated with the method output
ConfigurationElement collection = instance.Output.GetCollection();

// Looks for the publishing point and Invokes the desired method of the Publishing Point.
// In this case we are calling the Start method (others supported functions are "Shutdown" and "Stop")
foreach (var item in collection.GetCollection())
{
    if (item.Attributes["name"].Value.ToString().Equals(fileName))
    {
        var method = item.Methods["Start"];
        var methodInstance = method.CreateInstance();
        methodInstance.Execute();
        break;
    }
}

Remember that in order to use the previous code, you must have references to the following assembly:

Microsoft.Web.Administration.dll (can be found at IIS Directory %windir%\System32\inetSrv)

Hope this helps.

Happy streaming!

  Ezequiel,
  Have you been successful in using this code remotely with the ServerManager.OpenRemote(this.ServerName) method?
  
  Is there some specific configuration that needs to happen first on the box to enable the remote management?

  Hi
  i am using below code to get the list of all Publishing points.
  ConfigurationMethodInstance instance = liveStreamingConfig.Methods[METHODGETPUBPOINTS].CreateInstance();
  
  instance.Input[ATTR_SITENAME] = siteName;
  instance.Input[ATTR_VIRTUALPATH] = applicationPath;
  
  instance.Execute();
  
  ConfigurationElement collection = instance.Output.GetCollection();
  
  foreach (var item in collection.GetCollection())
  {
  retVal.Add(new PublishingPoint
  {
  SiteName = siteName,
  Path = applicationPath,
  Name = item.Attributes[ATTR_NAME].Value.ToString(),
  ArchiveState = (State)item.Attributes[ATTR_ARCHIVES].Value,
  FragmentState = (State)item.Attributes[ATTR_FRAGMENTS].Value,
  StreamState = (State)item.Attributes[ATTR_STREAMS].Value,
  PubState = (PublishingPointState)item.Attributes[ATTR_STATE].Value
  });
  LogDetails(“—————————————-”);
  LogDetails(“siteName: ” + siteName);
  LogDetails(“applicationPath: ” + applicationPath);
  LogDetails(“Name: ” + item.Attributes[ATTR_NAME].Value.ToString());
  LogDetails(“ArchiveState: ” + item.Attributes[ATTR_ARCHIVES].Value.ToString());
  LogDetails(“FragmentState: ” + item.Attributes[ATTR_FRAGMENTS].Value.ToString());
  LogDetails(“StreamState: ” + item.Attributes[ATTR_STREAMS].Value.ToString());
  LogDetails(“PubState: ” + item.Attributes[ATTR_STATE].Value.ToString());
  LogDetails(“”);
  }
  
  But i always get the item.Attributes[ATTR_STATE].Value as zero, whatever be the state.
  can you please help me why it is not showing the correct state?
  
  Additionally if I click the shutdown button I get an error:
  ————————-
  Exception Details: System.Runtime.InteropServices.COMException: The data is invalid. (Exception from HRESULT: 0x8007000D)
  
  Source Error:
  
  Line 277: var method =

  Line 280: break;
  Line 281: }

  Please suggest
  Thanks in advance.
