This is part 12 of my Exploring the .NET CoreFX Series.
In C++, the inline keyword allows a developer to provide a hint to the compiler that a particular method should be inlined. C# has the identical ability but uses an attribute instead:
internal class SecurePooledObject<T>
{
....
[MethodImpl(MethodImplOptions.AggressiveInlining)]
internal bool IsOwned<TCaller>(ref TCaller caller)
where TCaller : struct, ISecurePooledObjectUser
{
return caller.PoolUserId == _owner;
}
}
In System.Collections.Immutable, this attribute is used highly selectively — only once, in fact.
Recommendations
- In rare cases, consider using
MethodImpl(MethodImplOptions.AggressiveInlining)to suggest to the .NET runtime that a particular method should be inlined.
