Exemplos

O código de exemplo a seguir define um método que invoca para gerar o parâmetro de cadeia de caracteres Console.WriteLine passado para o método . Um CodeArgumentReferenceExpression faz referência ao argumento passado para o método pelo nome do parâmetro de método.

// Declare a method that accepts a string parameter named text.
CodeMemberMethod^ cmm = gcnew CodeMemberMethod;
cmm->Parameters->Add( gcnew CodeParameterDeclarationExpression( "String","text" ) );
cmm->Name = "WriteString";
cmm->ReturnType = gcnew CodeTypeReference( "System::Void" );
array<CodeExpression^>^ce = {gcnew CodeArgumentReferenceExpression( "test1" )};

// Create a method invoke statement to output the string passed to the method.
CodeMethodInvokeExpression^ cmie = gcnew CodeMethodInvokeExpression( gcnew CodeTypeReferenceExpression( "Console" ),"WriteLine",ce );

// Add the method invoke expression to the method's statements collection.
cmm->Statements->Add( cmie );

// A C++ code generator produces the following source code for the preceeding example code:
// private:
//  void WriteString(String text) {
//       Console::WriteLine(text);
// }

// Declare a method that accepts a string parameter named text.
CodeMemberMethod cmm = new CodeMemberMethod();
cmm.Parameters.Add( new CodeParameterDeclarationExpression("String", "text") );
cmm.Name = "WriteString";
cmm.ReturnType = new CodeTypeReference("System.Void");

// Create a method invoke statement to output the string passed to the method.
CodeMethodInvokeExpression cmie = new CodeMethodInvokeExpression( new CodeTypeReferenceExpression("Console"), "WriteLine", new CodeArgumentReferenceExpression("text") );

// Add the method invoke expression to the method's statements collection.
cmm.Statements.Add( cmie );

// A C# code generator produces the following source code for the preceeding example code:
//        private void WriteString(String text)
//        {
//            Console.WriteLine(text);
//        }

 ' Declare a method that accepts a string parameter named text.
 Dim cmm As New CodeMemberMethod()
 cmm.Parameters.Add(New CodeParameterDeclarationExpression("String", "text"))
 cmm.Name = "WriteString"
 cmm.ReturnType = New CodeTypeReference("System.Void")
 
 ' Create a method invoke statement to output the string passed to the method.
 Dim cmie As New CodeMethodInvokeExpression(New CodeTypeReferenceExpression("Console"), "WriteLine", New CodeArgumentReferenceExpression("text"))
 
 ' Add the method invoke expression to the method's statements collection.
 cmm.Statements.Add(cmie)

 ' A Visual Basic code generator produces the following source code for the preceeding example code:
 '		Private Sub WriteString(ByVal [text] As [String])
 '			Console.WriteLine([text])
 '		End Sub

Comentários
