这是我正在尝试做的代码：
Database myDB = DatabaseFactory.CreateDatabase();
bool IsAuthUser = myDB.ExecuteScalar("procIsAuthorizedUser", System.Environment.UserName);
If they are functionally identical, which is better in terms of performance?

System.Environment.UserNamereturns the identity under which the app pool that hosts your web app is running. If you're using Windows authentication and impersonation then it will be the actual user's name, however in all cases you're better off using the information provided by the HTTP context. There is no performance hit either way.
System.Environment.UserName返回承载您的 Web 应用程序的应用程序池正在运行的标识。如果您使用的是 Windows 身份验证和模拟，那么它将是实际用户的名称，但是在所有情况下，您最好使用 HTTP 上下文提供的信息。无论哪种方式，都不会影响性能。
