C#路径问题_空路径名是非法的?
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:
using System;
using System.Collections.Generic;

using System.Data;
using System.Drawing;
using System.Text;

}

}
}

}

}
while (length != 0);
}
catch (Exception ex)
{

}
finally
{
if (src != null)
src.Close();
if (dest != null)
dest.Close();
this.Close();
}
}
private void cpbtn_Click(object sender, EventArgs e)//多线程&&断点续传
{

// 在此处创建多线程复制文件
Thread thread = new Thread(new ThreadStart(this.CopyProcess));

thread.Start();
}
}
}
