Literal<T> Literal<T> Literal<T> Literal<T> Class


Represents an expression activity that returns a literal value of the specified type.

generic <typename T>
public ref class Literal sealed : System::Activities::CodeActivity<T>, System::Activities::XamlIntegration::IValueSerializableExpression
public sealed class Literal<T> : System.Activities.CodeActivity<T>, System.Activities.XamlIntegration.IValueSerializableExpression
type Literal<'T> = class
    inherit CodeActivity<'T>
    interface IValueSerializableExpression
Public NotInheritable Class Literal(Of T)
Inherits CodeActivity(Of T)
Implements IValueSerializableExpression
