CodeParameterDeclarationExpression can be used to represent code that declares a parameter for a method, property, or constructor.
The Name property specifies the name of the parameter. The Type property specifies the data type of the parameter. The Direction property specifies the direction modifier of the parameter. The CustomAttributes property specifies the attributes associated with the parameter.
The following example demonstrates use of CodeParameterDeclarationExpression to declare parameters of a method using different FieldDirection field reference type specifiers.
' Declares a method. Dim method1 As New CodeMemberMethod() method1.Name = "TestMethod" ' Declares a string parameter passed by reference. Dim param1 As New CodeParameterDeclarationExpression("System.String", "stringParam") param1.Direction = FieldDirection.Ref method1.Parameters.Add(param1) ' Declares a Int32 parameter passed by incoming field. Dim param2 As New CodeParameterDeclarationExpression("System.Int32", "intParam") param2.Direction = FieldDirection.Out method1.Parameters.Add(param2) ' A Visual Basic code generator produces the following source code for the preceeding example code: ' Private Sub TestMethod(ByRef stringParam As String, ByRef intParam As Integer) ' End Sub
// Declares a method.
CodeMemberMethod method1 = new CodeMemberMethod();
method1.set_Name("TestMethod");
// Declares a string parameter passed by reference.
CodeParameterDeclarationExpression param1 = new
CodeParameterDeclarationExpression("System.String", "stringParam");
param1.set_Direction(FieldDirection.Ref);
method1.get_Parameters().Add(param1);
// Declares a Int32 parameter passed by incoming field.
CodeParameterDeclarationExpression param2 = new
CodeParameterDeclarationExpression("System.Int32", "intParam");
param2.set_Direction(FieldDirection.Out);
method1.get_Parameters().Add(param2);
// A VJ# code generator produces the following source code for
// the preceeding example code:
// private void TestMethod(/** @ref */ String stringParam,
// /** @ref */ int intParam)
// {
// } //TestMethod
