Type Parameters

Name	Description
T	The element type

Clone<T>(T)

Clones an object by serializing and deserializing it, therefore it needs to be System.Runtime.Serialization.ISerializable"/>.

Declaration

Parameters

Type	Name	Description
T	source	The object to clone

Returns

Type	Description
T	The T.

Type Parameters

Name	Description
T	The type of the object to clone

Exceptions

Type	Condition
System.ArgumentException	Throws an execption, if the object is not serializable.
