我有一个从DefaultAppPool帐户运行的网络应用程序。我想将一些文件写入DefaultAppPool的AppData文件夹（或任何其他文件夹，可以从我的应用程序运行的帐户100％访问）
我试过
Environment.GetFolderPath(System.Environment.SpecialFolder.ApplicationData)
但由于某种原因，它返回一个空字符串。
Environment.GetFolderPath(System.Environment.SpecialFolder.UserProfile)
按预期返回C:\\Users\DefaultAppPool。
如何获取DefaultAppPool的AppData路径？
修改 此代码在Model
中执行答案 0 :(得分：1)
我这样做：
var path = string.Format("{0}\\{1}", Environment.GetFolderPath(System.Environment.SpecialFolder.UserProfile), "AppData")
答案 1 :(得分：0)
我是这样做的：

required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
