{

public class UserService {

public UserService() { }

private static String SQL_EMP_BY_LOGINNAME =

@"select USERID,USERNAME,PASSWORD from PHOTO_USERS where USERNAME = @USERNAME"; public static Dictionary<String, String> getUserByLoginName(String username) {

return DataAccess.ExecuteToSet(SQL_EMP_BY_LOGINNAME, "USERNAME", username); }

//修改密码

private static String SQL_UPDATEPSW_BY_USERID = @"update PHOTO_USERS set PASSWORD=@PASSWORD where USERID=@USERID";

public static bool UpdatePsw(Dictionary<string, string> userinfo) {

bool result = DataAccess.ExecuteNonQuery(SQL_UPDATEPSW_BY_USERID, userinfo); return result; } }

}

4）表示层的设计与实现 1.default.css设计

.bartype { color: blue;

background-color: green;

} .errormsg { font-size: 12pt; font-family: @宋体; color:Red; }

.barborder { border-style: solid; border-width: 1px; width: 200px;

vertical-align: middle; }
