推荐答案

可能，这是一个权限问题。



当您从命令行执行文件复制时，您将以登录用户身份运行它：所以使用目标文件夹进行访问用户权限。

当您的服务运行时，它不会以普通用户身份运行 - 因为在启动服务时没有用户登录 - 因此它获取了不同的权限。

您需要将服务分配给特定帐户，或者为目标文件夹提供适当的访问权限。

Probably, it's a permissions problem.

When you do a file copy from the command line, you are running it as the logged in user: so the destination folder is accessed using the user permissions.
When your service runs, it does not run as a "normal" user - because no user has been logged in when the services are started - so it acquires different permissions.
You either need to assign the service to a particular account, or give appropriate access permissions to your destination folder.
