Namespace:  System.CodeDom
Assembly:  System (in System.dll)

'Usage
Dim instance As CodeParameterDeclarationExpression

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

System.Object
  System.CodeDom.CodeObject
    System.CodeDom.CodeExpression
      System.CodeDom.CodeParameterDeclarationExpression
