To determine if a method is overridable, it is not sufficient to check that IsVirtual is true. For a method to be overridable, IsVirtual must be true and IsFinal must be false. For example, a method might be non-virtual, but it implements an interface method. The common language runtime requires that all methods that implement interface members must be marked as virtual; therefore, the compiler marks the method virtual final. So there are cases where a method is marked as virtual but is still not overridable.
To establish with certainty whether a method is overridable, use code such as this:
if (MethodInfo.IsVirtual && !MethodInfo.IsFinal)
If IsVirtual is false or IsFinal is true, then the method cannot be overridden.
