Methods

	Name	Description
	CompareTo	Compares the current StateRecord object to obj.
	Equals	Determines whether the current StateRecord object is equal to obj. (Overrides ObjectEquals(Object))
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GenerateBinaryImage	Generates binary image of the StateRecord and copies it into the given buffer, for BinaryLength bytes.
	GetHashCode	Returns the hash code for the current StateRecord object. (Overrides ObjectGetHashCode)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	ParseBinaryImage	Initializes StateRecord from the specified buffer.
	ToString	Returns the text representation of StateRecord object. (Overrides ObjectToString)
