我有以下数据库设计： 员工表：用户名，姓名，工作等 角色表：RoleID，RoleName UserRole表：UserRoleID，用户名，RoleID
我正在为公司的部门开发一个Intranet基于Web的应用程序。此应用程序只能由我的部门员工访问，并且应该是具有其角色（访问类型）的员工的用户名在网站顶部。我有四个不同的角色;经理，贡献，助理和用户。我现在想要的是做以下事情： 1.检查用户是否是部门员工之一。 2.如果没有，他会看到一个错误页面 3.如果是，这是他第一次访问该网站，那么他将获得一个用户角色，除非管理员添加他并给他一个其他角色，否则该角色应立即显示在用户名的顶部。
除非管理员确定他在数据库中的访问权限，否则如果用户是系统新用户，则除了角色没有显示在顶部之外，一切都运行良好。所以我如何显示任何默认角色系统的新用户？
我的代码隐藏如下：
private bool CheckUsername(string username)
{
if (Service.GetPerson(username).GetProperty("RES_NETID").Equals("-"))
return false;
else if (Security.isPMODMember(username))
return true;
else
return false;
//string connString = "Data Source=localhost\\sqlexpress;Initial Catalog=psspdb;Integrated Security=True";
//string cmdText = "SELECT Count(*) FROM employee WHERE Username = '" + username + "'";
//using (SqlConnection conn = new SqlConnection(connString))
//{
// conn.Open();
// // Open DB connection.
// using (SqlCommand cmd = new SqlCommand(cmdText, conn))
// {
// int count = (int)cmd.ExecuteScalar();
// // True (> 0) when the username exists, false (= 0) when the username does not exist.
// return (count > 0);
// }
//}
}
