我查看了下msdn,关于ObjectCollection 的知识.
-----------------------------------------------------
.NET Framework Class Library for Silverlight
ObjectCollection Class
Namespace: System.Windows.Controls
Assembly: System.Windows.Controls (in System.Windows.Controls.dll)
-------------------------
http://msdn.microsoft.com/en-us/library/system.windows.controls.objectcollection%28v=VS.96%29.aspx?appId=Dev10IDEF1&l=EN-US&k=k%28SYSTEM.WINDOWS.CONTROLS.OBJECTCOLLECTION%29;k%28TargetFrameworkMoniker-%22SILVERLIGHT&k=VERSION=V4.0%22%29;k%28DevLang-CSHARP%29&rd=true
但是我添加了 System.Windows.Controls.dll 但还是不能用 ObjectCollection 类.
但我下载了一个demo,它是可以用ObjectCollection 类.
希望大家帮帮忙!
谢谢!
