IsValid

Is this object valid (see remarks)?

public static method	IsValid (object obj)
type	bool
params	obj		The object to check.
returns			true if the object is valid, false if not.

Remarks:

An object is considered valid if it is in one of the following lifecycle states:

• Initializing (the Initialize method is being called).
• Initialized
• Disposing (the Dispose method is being called).

An non-null object that does not implement the ILifecycleState interface is always valid. Null objects are always invalid.
