顺带一提 这个是c#语言 C#吧里听说很不友好 只好求助于次
网上说把prvite改public没有用


只有四个同样的错误描述为：错误 4 “KTVmusic.frmDaiGe.lvPlay”不可访问，因为它受保护级别限制 C:\Documents and Settings\Administrator\桌面\软件开发项目\KTVmusic\KTVmusic\frmNumber.cs 111 43 KTVmusic

这是另一边的窗体代码 不管有没有人回答
还是再次谢过 坐等解救.....thank you


代码太长了，没看。。不过估计是你读内存数据同时又去修改它了，我做播放器也遇到这个问题，楼主为什么不去C#吧发帖？


“网上说把prvite改public没有用”
你修改的是什么地方？
