[<System.Runtime.InteropServices.DispId(47)>]
abstract member AddParameter : string * obj * obj -> EnvDTE.CodeParameter

Public Function AddParameter (Name As String, Type As Object, Optional Position As Object) As CodeParameter

Parameters

Name: String

Required. The name of the parameter.

Type: Object

Required. A vsCMTypeRef constant indicating the data type that the function returns. This can be a CodeTypeRef object, a vsCMTypeRef constant, or a fully qualified type name.

Position: Object

Optional. Default = 0. The code element after which to add the new element. If the value is a CodeElement, then the new element is added immediately after it.

If the value is a Long data type, then AddParameter(String, Object, Object) indicates the element after which to add the new element.

Because collections begin their count at 1, passing 0 indicates that the new element should be placed at the beginning of the collection. A value of -1 means that the element should be placed at the end.

Returns

CodeParameter

A CodeParameter object.

Attributes: DispIdAttribute

Examples

 Sub AddParameterExample(ByVal dte As DTE2)  

    ' Before running this example, open a code document from a project  
    ' and place the insertion point inside a function.  
    Try  
        ' Retrieve the CodeFunction at the insertion point.  
        Dim sel As TextSelection = _  
            CType(dte.ActiveDocument.Selection, TextSelection)  
        Dim fun As CodeFunction = _  
            CType(sel.ActivePoint.CodeElement( _  
            vsCMElement.vsCMElementFunction), CodeFunction)  

        ' Add a parameter to the function.  
        fun.AddParameter("TestParam", vsCMTypeRef.vsCMTypeRefInt)  
    Catch ex As Exception  
        MsgBox(ex.Message)  
    End Try  

End Sub

 public void AddParameterExample(DTE2 dte)  
{  
    // Before running this example, open a code document from a project  
    // and place the insertion point inside a function.  
    try  
    {  
        // Retrieve the CodeFunction at the insertion point.  
        TextSelection sel =   
            (TextSelection)dte.ActiveDocument.Selection;  
        CodeFunction fun =   
            (CodeFunction)sel.ActivePoint.get_CodeElement(  
            vsCMElement.vsCMElementFunction);  

        // Add a parameter to the function.  
        fun.AddParameter("TestParam", vsCMTypeRef.vsCMTypeRefInt, -1);  
    }  
    catch (Exception ex)  
    {  
        MessageBox.Show(ex.Message);  
    }  
}

Remarks

Native Native Visual C++ requires the colon-separated (::) format for its fully qualified type names. All other languages support the period-separated format.

The correctness of the arguments is determined by the language behind the code model.

Note

The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model Element Values Can Change in Discovering Code by Using the Code Model (Visual Basic).
