推荐答案

该消息使用非常简单的英语-该位置的文件已经存在.如果要覆盖文件，请使用重载的方法 File.Copy方法(字符串，字符串，布尔值) [^ ].将true传递给overwrite参数，它应该很好.

The message is in a very simple English - the file at that location already exist. If you want to overwrite the file, use the overloaded method File.Copy Method (String, String, Boolean)[^]. Pass true to the overwrite parameter and it should be good.
