  • Article

If the expression represents a class or a structure, this property gets a list of member variables as an Expressions collection.

Namespace:  EnvDTE100
Assembly:  EnvDTE100 (in EnvDTE100.dll)

Syntax

'Declaration
ReadOnly Property DataMembers As Expressions
    Get

Expressions DataMembers { get; }

property Expressions^ DataMembers {
    Expressions^ get ();
}

abstract DataMembers : Expressions

function get DataMembers () : Expressions

Property Value

Type: EnvDTE.Expressions
An Expressions collection.

Implements

Expression.DataMembers

Remarks

See Expressions in the Debugger for general information about expressions.

Examples

The following example demonstrates how to use the DataMembers property.

To test this property:

  1. The target application must contain a class A. The function Main must create an instance of a class A called "a".

  2. Set a breakpoint in the function Main after an instance of class A is created and its member variables are initialized.

  3. Run the target application in the debug mode.

  4. When the application stops at the breakpoint, run the add-in.

public static void DataMembers(DTE dte)
{
    // Setup debug Output window.
    Window w = (Window)dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput);
    w.Visible = true;
    OutputWindow ow = (OutputWindow)w.Object;
    OutputWindowPane owp = ow.OutputWindowPanes.Add("DataMembers Property Test");
    owp.Activate();

    // "a" is an instance of class A.
    EnvDTE100.Expression2 exp1 = dte.Debugger.GetExpression("a", true, 1);
    EnvDTE.Expressions exps = exp1.DataMembers;
    foreach(EnvDTE100.Expression2 exp in exps)
        owp.OutputString(exp.Name + "\n");
}

Shared Sub DataMembers(ByRef dte As EnvDTE.DTE)
    Dim exp As EnvDTE100.Expression2 = dte.Debugger.GetExpression("a", True, 1)
    Dim exps As EnvDTE.Expressions = exp.DataMembers
    Dim str As String = vbCrLf
    For Each exp In exps
        str += vbCrLf + vbTab + exp.Name
    Next
    MessageBox.Show("List of class A data members: " + _
                    str, "Expression Test - Data Members Property")
End Sub
