推荐答案
您可以使用Application.UserAppDataPath从DLL - 只需从DLL项目中添加引用到System.Windows.Forms组装
You can use Application.UserAppDataPath from a DLL - simply add a reference to the System.Windows.Forms assembly from your DLL project.
但要注意，如果您的DLL用于Windows服务或服务器应用程序，如ASP.NET，它可能会在不具有配置文件的服务帐户运行 - 在这种情况下UserAppDataPath将不存在。这可能是主要的原因，应用类System.Windows.Forms命名空间。
However be aware that if your DLL is used in a Windows Service or Server application such as ASP.NET, it may run under an service account that does not have a profile - in this case UserAppDataPath won't exist. This is probably the main reason the Application class is in the System.Windows.Forms namespace.
