'Declaration
ReadOnly Property Collection As Expressions

Property Value
Type: EnvDTE.Expressions
An Expressions collection.
Examples
The following example demonstrates how to use the Collection 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 Collection(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("Collection Property Test");
owp.Activate();
EnvDTE100.Expression2 exp = dte.Debugger.GetExpression("a", true, 1);
EnvDTE.Expressions exps = exp.DataMembers;
owp.OutputString("\nExpression count: " + exps.Count);
owp.OutputString("\nEdition of the environment: " + exps.DTE.Edition);
owp.OutputString("\nThe name of the current program: " +
exps.Parent.CurrentProgram.Name);
owp.OutputString("\nSecond expression: " + exps.Item(2).Name);
}
Shared Sub Collection(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
str = "Expression count: " + exps.Count.ToString()
str += vbCrLf + "Edition of the environment: " + exps.DTE.Edition
str += vbCrLf + "The name of the current program: " + _
exps.Parent.CurrentProgram.Name
str += vbCrLf + "Second expression: " + exps.Item(2).Name
MessageBox.Show(str, "Expression Test - Collection Property")
End Sub
