Quick Tip: Local Central Admin SPWebApplication

August 11, 2008 — Keith Dahlby

I’ve seen several incoming searches like “SPWebApplication for Central Admin”, so hopefully this will provide a quick answer:

SPAdministrationWebApplication.Local

Which really just returns:

SPAdministrationWebApplication.GetInstanceLocalToFarm(SPFarm.Local);

And a quick example in PowerShell for good measure:

PS C:\> [system.reflection.assembly]::LoadWithPartialName("Microsoft.SharePoint") > $null
PS C:\> $ca = [Microsoft.SharePoint.Administration.SPAdministrationWebApplication]::Local
PS C:\> $ca.DefaultServerComment
SharePoint Central Administration v3
PS C:\> $ca.AdministrativeTasks.Items | select Title -first 3

Hope this helps!

Finding an SPWebApplication by ID

June 14, 2008 — Keith Dahlby

Not sure if it was me that prompted Neil’s post, but a question that came up earlier today was how to retrieve an SPWebApplication from its ID. Neil suggested trying to retrieve the generic SPPersistedObject by that ID, which eventually led me to SPFarm.GetObject(Guid).

SPFarm farm = SPFarm.Local;
Guid webAppId = new Guid("e81de291-7205-42fe-8228-422c6bbed277");
SPWebApplication webApp = farm.GetObject(webAppId) as SPWebApplication;
Debug.WriteLine(webApp);

Have I overlooked another method, or is this really the only way?

Bonus tip: Use SPAdministrationWebApplication.Local to get the web app for Central Admin.
