Esempio

In questo esempio viene illustrato l'uso di un oggetto CodePropertySetValueReferenceExpression per rappresentare l'argomento valore passato a un blocco di istruzioni value set di proprietà.

// Declares a type.
CodeTypeDeclaration type1 = new CodeTypeDeclaration("Type1");

// Declares a constructor.
CodeConstructor constructor1 = new CodeConstructor();
constructor1.Attributes = MemberAttributes.Public;
type1.Members.Add( constructor1 );

// Declares an integer field.
CodeMemberField field1 = new CodeMemberField("System.Int32", "integerField");
type1.Members.Add( field1 );

// Declares a property.
CodeMemberProperty property1 = new CodeMemberProperty();
// Declares a property get statement to return the value of the integer field.
property1.GetStatements.Add( new CodeMethodReturnStatement( new CodeFieldReferenceExpression(new CodeThisReferenceExpression(), "integerField") ) );
// Declares a property set statement to set the value to the integer field.
// The CodePropertySetValueReferenceExpression represents the value argument passed to the property set statement.
property1.SetStatements.Add( new CodeAssignStatement( new CodeFieldReferenceExpression(new CodeThisReferenceExpression(), "integerField"),
                                    new CodePropertySetValueReferenceExpression() ) );
type1.Members.Add( property1 );

// A C# code generator produces the following source code for the preceeding example code:

//    public class Type1
//    {
//
//        private int integerField;
//
//        public Type1()
//        {
//        }
//
//        private int integerProperty
//        {
//            get
//            {
//                return this.integerField;
//            }
//            set
//            {
//                this.integerField = value;
//            }
//        }
//    }

' Declares a type.
Dim type1 As New CodeTypeDeclaration("Type1")

' The CodePropertySetValueReferenceExpression represents the value argument passed to the property set statement.
property1.SetStatements.Add(New CodeAssignStatement(New CodeFieldReferenceExpression(New CodeThisReferenceExpression(), "integerField"), New CodePropertySetValueReferenceExpression()))
type1.Members.Add(property1)

' A Visual Basic code generator produces the following source code for the preceeding example code:

'   Public Class Type1
'
'       Private integerField As Integer
'
'       Public Sub New()
'           MyBase.New()
'       End Sub
'
'       Private Property integerProperty() As Integer
'           Get
'               Return Me.integerField
'           End Get
'           Set(ByVal Value As Integer)
'               Me.integerField = value
'           End Set

Commenti

CodePropertySetValueReferenceExpression rappresenta l'argomento valore di una chiamata al metodo del set di proprietà all'interno di una dichiarazione del metodo del set di proprietà.

Un metodo set di proprietà assegna o usa in genere il valore assegnato alla proprietà . All'interno del metodo del set di proprietà, questo valore è rappresentato da una variabile implicita rappresentata in CodeDOM da un oggetto CodePropertySetValueReferenceExpression.
