Assembly:  mscorlib (in mscorlib.dll)

public static object GetSafeUninitializedObject(
	Type type


Type: System.Type

The type of object to create.

Return Value

Type: System.Object

A zeroed object of the specified type.

Exception Condition

The type parameter is null.


The type parameter is not a valid common language runtime type.


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. GetSafeUninitializedObject 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.

GetSafeUninitializedObject converts all class level Link Demands to Demands to ensure that all direct and indirect callers have the permissions that the demand specifies. Use GetSafeUninitializedObject to increase the level of security when deserializing from a partially trusted source. For better performance in full trust scenarios, use GetUninitializedObject.
