我要在winfrom界面中实现一个数据加载等待界面。我使用的方法是： ThreadStart threadDelegate = new ThreadStart(Waiting);
if(newThread != null && newThread.ThreadState != ThreadState.Aborted)
{
newThread.Abort();
}
newThread = new Thread(threadDelegate);
newThread.Start(); //操作事件
doLoading（）; if (newThread != null && newThread.IsAlive)
{ newThread.Abort(); //销毁线程，自动回收托管资源
} private void Waiting()
{ Frm_Wait frm_wait1 = new Frm_Wait(); //申明一个等待界面
frm_wait1.Location = new Point(525, 277);
frm_wait1.ShowDialog(); //线程等待 }
但是每次加载了时间的时候，都会出现frm_wait1这个界面没有完全销毁，或者frm_wait1这个界面的图片变成红色的矩形框，有时候则会报GDI一般性错误，如果数据事件doLoading执行的时间太短了，则会出现系统退出。
请求各位大哥大姐帮帮忙，怎么界面这个数据加载等待界面的问题
if(newThread != null && newThread.ThreadState != ThreadState.Aborted)
{
newThread.Abort();
}
newThread = new Thread(threadDelegate);
newThread.Start(); //操作事件
doLoading（）; if (newThread != null && newThread.IsAlive)
{ newThread.Abort(); //销毁线程，自动回收托管资源
} private void Waiting()
{ Frm_Wait frm_wait1 = new Frm_Wait(); //申明一个等待界面
frm_wait1.Location = new Point(525, 277);
frm_wait1.ShowDialog(); //线程等待 }

你需要先注册codeproject网站的用户，用email地址很快。
源代码和实现说明下图实现的是拷贝大文件时等待的画面，你可以自己修改后，点击拷贝，就是你点击加载数据源的情况，然后显示进度条，或者一个动画的窗体都可以！
另外，你这样的写法是需要线程间通信的，就是说，你新开启的线程要知道doLoading之后再结束form
