I'm trying to port my game from XNA to SharpDX, but I can't find the solution for my problem:

I'm getting this error. I don't know how fix it.

PlayerIndex? means that it can be null or contain a value. It's a synonym to Nullable<PlayerIndex>.
You can either change it to PlayerIndex or, when using it, use it as playerIndex.Value so you refer to the value it may be containing, you can also check if this is the case before using it by checking the HasValue property of the type.
More info on nullable types here.
If that doesn't help, try to be more specific on the line of code throwing the error, instead of copying the whole thing.
