Beispiele

In diesem Beispiel wird die Verwendung eines CodePropertySetValueReferenceExpression veranschaulicht, um das Wertargument darzustellen, das an einen Eigenschaftssatzwert-Anweisungsblock übergeben wird.

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

// Declares a constructor.
CodeConstructor^ constructor1 = gcnew CodeConstructor;
constructor1->Attributes = MemberAttributes::Public;
type1->Members->Add( constructor1 );

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

// Declares a property.
CodeMemberProperty^ property1 = gcnew CodeMemberProperty;

// Declares a property get statement to return the value of the integer field.
property1->GetStatements->Add( gcnew CodeMethodReturnStatement( gcnew CodeFieldReferenceExpression( gcnew 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( gcnew CodeAssignStatement( gcnew CodeFieldReferenceExpression( gcnew CodeThisReferenceExpression,"integerField" ),gcnew 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 
//            {

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

// 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:

Hinweise

CodePropertySetValueReferenceExpression stellt das Wertargument eines Methodenaufrufs eines Eigenschaftssatzes innerhalb einer Methodendeklaration des Eigenschaftssatzes dar.

Eine Eigenschaftssatzmethode weist in der Regel den der Eigenschaft zugewiesenen Wert zu oder verwendet diesen. Innerhalb der Eigenschaftssatzmethode wird dieser Wert durch eine implizite Variable dargestellt, die in CodeDOM durch einen CodePropertySetValueReferenceExpressiondargestellt wird.
