VB to C#: Does Learning = Job?

C# seems the rampant job requirement in the Tampa Bay, FL area {my sector of the world}. Since I am seeking employment, even after 10 + years developing in VB I wonder if spending my unemployed days learning C# is a benefit.
Specifically, will learning C# after all these years jump start my career again?
Will it lead to a job offer?
Finally, is it better to take a class or go the self-taught route?
