C#多线程问题

卡卡Gemini 2010-06-08 02:49:25

采用的是backgroundworker，下面是里面的函数，主要就是调用一个后台对程序进行编译的过程，showdrawform是一个委托，里面会建立一个窗体(我知道这样做可能不太合理，但是我没有更好的办法)，说下程序的功能：

通过dos命令，进入相关目录，然后执行命令编译，编译完生成文件1（对应命令setever），然后执行命令转换（对应命令converse），转换完生成文件2，然后启用showdrawform函数，生成一个对话框。在此对话框From_Load事件中会去读取文件2，但是现在执行这段代码会卡死，请大家参谋下
