public class test
{
BackgroundWorker _Init = new BackgroundWorker();
public void CarouselInit()
{
_Init.DoWork += new DoWorkEventHandler(_DoWork_Init);
_Init.RunWorkerAsync();
}
void _DoWork_Init(object sender, DoWorkEventArgs e)
{
}
}
如上代码，当第二次调用CarouselInit()时，_DoWork_Init会被执行两次，那么，该怎么判断_Init.DoWork已经绑定了一个方法呢？
请大侠们教诲教导啊！
------解决方案--------------------------------------------------------
加一个全局变量
private bool bInited=false;
public class test
{
BackgroundWorker _Init = new BackgroundWorker();
private bool bInited=false;
public void CarouselInit()
{
if(!bInited)
{
bInited=true;
_Init.DoWork += new DoWorkEventHandler(_DoWork_Init);
}
_Init.RunWorkerAsync();
}
void _DoWork_Init(object sender, DoWorkEventArgs e)
{
}
}

哥们 你不会在构造时候来注册方法啊
