+Classes with indexed properties can also be used like classes with dynamic arrays. Please see this sample:
+<code visualfoxpro>class IndexedProperty
+protect _oValues as Dictionary<string,string>
+constructor()
+  _oValues		:= Dictionary<string,string>{}
+return
+property self[cName as string] as string
+  get
+    if _oValues:ContainsKey( cName )
+      return _oValues[cName]
+    else
+      return "< not assigned >"
+    endif
+  end get
+  set
+    if _oValues:ContainsKey( cName )
+      _oValues[cName]		:= value
+    else
+      _oValues:Add( cName, value )
+    endif
+end set
+end property
+end class</code>
+To be used like this:
+<code visualfoxpro>oObject := IndexedProperty{}
+oObject["MyProp"] := "Hello X#"
+oObject["Prop2"] := "Hello again"
+System.Console.WriteLine( "MyProp:" + oObject["MyProp"] )
+System.Console.WriteLine( "Prop2:" + oObject["Prop2"] )
+System.Console.WriteLine( "Prop3:" + oObject["Prop3"] )</code>
