万分火急
如题。。具体希望贴出代码。。使用多线程移动一个文件到另一个地方。。谢谢 --------------------编程问答-------------------- 你是说另开一个线程吧？static void Move(Object args)
{
string[] files = (string[])args;
File.Move(files[0], files[1]);
}
调用：：
string[] files={"C:\\a.txt","C:\\b.txt"};
Thread t = new Thread(new ParameterizedThreadStart(Move));
t.Start(files); --------------------编程问答-------------------- new Thread((ThreadStart)delegate { A(); }).Start();
static void A()
{
File.Move("","");
}
new Thread((ThreadStart)delegate
{File.Move("","");
}).Start();
--------------------编程问答-------------------- 是用线程将一个文件复制到另一个文件吧？

补充：.NET技术 , C#
