Expression.DataMembers Property
If the expression represents a class or a structure, this property gets a list of member variables as an Expressions collection.
Namespace: EnvDTE
Assembly: EnvDTE (in EnvDTE.dll)
Syntax
'Declaration
ReadOnly Property DataMembers As Expressions
Expressions DataMembers { get; }
property Expressions^ DataMembers {
Expressions^ get ();
}
abstract DataMembers : Expressions
function get DataMembers () : Expressions
Property Value
Type: EnvDTE.Expressions
An Expressions collection.
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:
The target application must contain a class A. The function Main must create an instance of a class A called "a".
Set a breakpoint in the function Main after an instance of class A is created and its member variables are initialized.
Run the target application in the debug mode.
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.
EnvDTE.Expression exp1 = dte.Debugger.GetExpression("a", true, 1);
EnvDTE.Expressions exps = exp1.DataMembers;
foreach(EnvDTE.Expression exp in exps)
owp.OutputString(exp.Name + "\n");
}
Shared Sub DataMembers(ByRef dte As EnvDTE.DTE)
Dim exp As EnvDTE.Expression = 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
