你把 代码复制过去,你 做个窗体 就可以调试啊,我的问题是 timer启动不了,
干脆不用 timer ,用多线程 做就不会有问题。。

调试一下!!!!!
if (this.lab1.Location.Y == this.Height)
                {
                   this.timer1.Enabled = true;
                    this.lab1.Dispose();
                    break;     }              
  应该是这一段有问题!!  条件可能不成立!!那么timer1就没法变为true了!!自然就没法往下运行了!建议楼主调试一下!!若不会调试!在这个if段加个:messagebox.show("已经到这里了")来测试一下,是否程序已经运行到这了!!!

调试过,设置断点跟踪,监视变量,那里没有问题,而且 this.timer1.Enabled = true 执行了,但是 就是不产生字母往下掉。。。
