如何在 Binarium 中验证帐户
WEB页面代码裡
myus为null
public Users adminLogin(Users users)
using (DataClassesDataContext dataCC = new DataClassesDataContext())
Users myus = new Users(); //myus.LoginId和myus.LoginPwd这边应该是空字符串
var result = from u in dataCC.Users where myus.LoginId == users.LoginId && myus.LoginPwd == users.LoginPwd select u;
Users returnUser = null;
foreach (Users item in result)
myus.UserRoles = new UserRoles();
myus.UserRoles.Id = Convert.ToInt32(item.UserRoleId);
returnUser = myus;
break;
>
return returnUser;
