How to load data from db just after the app launch?

Question

hello, I'm learning xamarin, android c# development and I can't just find a solution.. how to write full statement - if database is not empty, then set this textview on MainLauncher as data from this database?
At the beginning, database is empty. I want the user to input data in DialogFragment which shows after button click, and then when he opens app, data is automatically showed om the screen.
I tried something like this, but I had crashes and bugs and that's impossible for me...(onCreate)
if(db.table<MyDatabase>().Count() != 0){
// is not empty, but here is first error
textview.Text = db.Get<MyDatabase>(1)
}

hi adam,
Maybe you can take a look at NULL and ANY. Try yo debug te problem with a try/catch block. It will profide you with a bit more info. also you should look up debugging in VS. Because you can use a breakpoint and see where the error is created and wy It shows up.
Best Of Luck!!!
