Gets a collection of all of the attributes for the delegate.

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

Syntax

'Declaration
ReadOnly Property Attributes As CodeElements

'Usage
Dim instance As CodeDelegate2 
Dim value As CodeElements 

value = instance.Attributes

CodeElements Attributes { get; }

property CodeElements^ Attributes {
    CodeElements^ get ();
}

function get Attributes () : CodeElements

Property Value

Type: EnvDTE.CodeElements
A CodeElements collection.

Implements

CodeDelegate.Attributes

Remarks

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.

Delegate Sub MySubDelegate(ByVal x As Integer)

public delegate void MySubDelegate(int x);

Public Sub CodeDelegateExample(ByVal dte As DTE2)
    ' Before running this example, open a code document from a 
    ' project and place the insertion point inside a class 
    ' definition.
    Try
        ' Retrieve the CodeClass at the insertion point.
