我添加了我的github存储库:您是否尝试以管理员身份运行我假设一定有原因不使用File.Copy()?我将app.manifest文件上的level=“asInvoker”uiAccess=“false”更改为level=“requireAdministrator”uiAccess=“false”,但仍然无法运行3更多要尝试的内容1。右键单击文件夹并选中“安全”选项卡,验证权限,修改应用程序在2下运行的用户的权限。如果您使用IIS,请检查IIS是否具有正确的权限3。检查并设置文件属性示例:
file.SetAttributes(file,FileAttributes.Normal)
@Clint我写了一个文件(很抱歉),但我正在尝试复制一个文件夹及其所有子目录
