The following example code defines a method that invokes Console.WriteLine
to output the string parameter passed to the method. A CodeArgumentReferenceExpression references the argument passed to the method by method parameter name.
// 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
CodeArgumentReferenceExpression can be used in a method to reference the value of a parameter that has been passed to the method.
The ParameterName property specifies the name of the parameter to reference.
