运用多线程进行文件复制,编译成功,复制时提示空路径名是非法的
在System.Arguement Exception 中第一次偶然出现的"mscorlib.dll"类型的异常,但是我在下面不是已经结合了文件夹更文件名称了吗?提示空路径是/的转义字符的问题么? 就是把"C:\aa\bb"变为"C:\\aa\\bb"?应该怎么解决?
附上整个工程文件,求各位指出错误及解决方法..谢谢..
代码如下:

你怎么不利用vs的强大的各种调试窗口功能，跟踪一下，很少几个断点就能确定的

嗯...发现是无法将变量的路径赋值给this. this.srcFile和this.destFile..不过.一样不知道怎么解决. 哎..

原来我把读取路径的语句放在初始化窗体处,导致一开始路径的值就固定了.不能改变.现已解决`~可以闭贴了.

谢谢yyltt兄的提点啊~
