Syntax

Copy

[SerializableAttribute]
public struct ObjectId : IComparable<ObjectId>, 
	IEquatable<ObjectId>, IConvertible

<SerializableAttribute>
Public Structure ObjectId
	Implements IComparable(Of ObjectId), IEquatable(Of ObjectId), 
	IConvertible

[<SealedAttribute>]
[<SerializableAttribute>]
type ObjectId =  
    struct
        interface IComparable<ObjectId>
        interface IEquatable<ObjectId>
        interface IConvertible
    end

The ObjectId type exposes the following members.

	GetHashCode	Gets the hash code. (Overrides ValueTypeGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Pack	Obsolete. Packs the components of an ObjectId into a byte array.
	Parse	Parses a string and creates a new ObjectId.
	ToByteArray	Converts the ObjectId to a byte array.
	ToByteArray(Byte, Int32)	Converts the ObjectId to a byte array.
	ToString	Returns a string representation of the value. (Overrides ValueTypeToString.)
	TryParse	Tries to parse a string and create a new ObjectId.
	Unpack	Obsolete. Unpacks a byte array into the components of an ObjectId.
