FormatterServices.GetUninitializedObject Method

Creates a new instance of the specified object type.

Namespace:  System.Runtime.Serialization
Assembly:  mscorlib (in mscorlib.dll)

public static Object GetUninitializedObject(
	Type type


Type: System.Type
The type of object to create.

Return Value

Type: System.Object
A zeroed object of the specified type.


The type parameter is null.


The caller does not have the required permission.

Because the new instance of the object is initialized to zero and no constructors are run, the object might not represent a state that is regarded as valid by that object. The current method should only be used for deserialization when the user intends to immediately populate all fields. It does not create an uninitialized string, since creating an empty instance of an immutable type serves no purpose.


You cannot use the GetUninitializedObject method to create instances of types that derive from the ContextBoundObject class.
