CodeDelegate2.AddAttribute Method

Creates a new attribute code construct and inserts the code in the correct location.

Namespace:  EnvDTE80
Assembly:  EnvDTE80 (in EnvDTE80.dll)

Syntax

'Declaration
Function AddAttribute ( _
    Name As String, _
    Value As String, _
    Position As Object _
) As CodeAttribute

CodeAttribute AddAttribute(
    string Name,
    string Value,
    Object Position
)

CodeAttribute^ AddAttribute(
    String^ Name, 
    String^ Value, 
    Object^ Position
)

abstract AddAttribute : 
        Name:string * 
        Value:string * 
        Position:Object -> CodeAttribute 

function AddAttribute(
    Name : String, 
    Value : String, 
    Position : Object
) : CodeAttribute

Parameters

• Name
  Type: System.String
  Required. The name of the new attribute.

• Value
  Type: System.String
  Required. The value of the attribute, which may be a list, separated by commas, of parameters for a property that has parameters.

• Position
  Type: System.Object
  Optional. Default = 0. The code element after which to add the new element.
  If Value is a Long data type, then AddAttribute 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 the element should be placed at the end.

Return Value

Type: EnvDTE.CodeAttribute
A CodeAttribute object.

Implements

CodeDelegate.AddAttribute(String, String, Object)

Remarks

If the attribute already exists, AddAttribute adds another. This may be incorrect for the attribute or 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).

Examples

Before running this example, load a project with a class and insert the following line along with the example code. After both the line and the example code are added, click the Delegate line to place the insertion point there, and then run the example.

[VisualBasic]

Delegate Sub MySubDelegate(ByVal x As Integer)

[C#]

public delegate void MySubDelegate(int x);

[VisualBasic]

Public Sub addDelegateAttribExample(ByVal dte As DTE2)
    Try
        ' Retrieve the CodeClass at the insertion point.
        Dim sel As TextSelection = _
          CType(dte.ActiveDocument.Selection, TextSelection)
        Dim del As CodeDelegate2 = _
          CType(sel.ActivePoint.CodeElement( _
        vsCMElement.vsCMElementDelegate), CodeDelegate2)

        ' Add a new attribute to the delegate.
        del.AddAttribute("someNewAttribute", "someValue", -1)
    Catch ex As System.Exception
        MsgBox(ex.ToString)
    End Try
End Sub
