Getting RemoteAppUrl programmatically inside AppEventReciever

Hi,

I want the value of RemoteAppUrl after app istallation inside AppEventReciever. Please suggest how can I find the same.

I tried AppInstance.RemoteAppUrl property, but not sure how can I get the reference of AppInstance class programmatically.

Below is the powershell script for same:

 $appInstance = Get-SPAppInstance -Web $web.Url | Where{$_.Title -eq $appTitle}

but i want do it programmatically.

Thanks,

Ashish H
