ImportAttribute.AllowDefault Property

Definition

Gets or sets a value that indicates whether the property, field, or parameter will be set to its type's default value when an export with the contract name is not present in the container.

public:
 property bool AllowDefault { bool get(); void set(bool value); };
public bool AllowDefault { get; set; }
member this.AllowDefault : bool with get, set
Public Property AllowDefault As Boolean

Property Value

true if the property, field, or parameter will be set to its type's default value when there is no export with the ContractName in the CompositionContainer; otherwise, false. The default is false.

Remarks

The default value of the type of a property, field, or parameter is null for reference types and zero for numeric value types. For other value types, the default value will be each field of the value type initialized to zero if the field is a value type, or null if the field is a reference type.
