public enum QuestionType { Text = 0, MultipleChoice = 1 } public interface IQuestion { string Title { get; set; } QuestionType Category { get; } } public abstract class QuestionBase : IQuestion { public string Title { get; set; } public abstract QuestionType Category { get; } public virtual string GetAnswer() { return "默认答案"; } } public class TextQuestion : QuestionBase { public override QuestionType Category { get { return QuestionType.Text; } } public override string GetAnswer() { return "文本答案"; } } public class MultipleChoiceQuestion : QuestionBase { public override QuestionType Category { get { return QuestionType.MultipleChoice; } } public override string GetAnswer() { return "单选答案"; } }
第4题：
public class Product { public string Name { get; set; } public string IsDeleted { get; set; } } public static class ProductExtension { public static IQueryable<Product> WhereNotDeleted(this IQueryable<Product> query) { return query.Where(p => p.IsDeleted != "是"); } } public class ProductService { public List<Product> GetActiveProducts(IQueryable<Product> query) { return query.WhereNotDeleted().ToList(); } }
第5题：
select T1.Name,T2.[Year],T2.[Month],T2.InCome from [User] as T1 inner join(select UserId,[Year],[Month],COUNT(Amount) AS InCome from InCome group by UserId,[Year],[Month]) as T2on T1.Id=T2.UserIdorder by T2.UserId,T2.[Year],T2.[Month]
第6题：
public class User { public int Id { get; set; } public string Name { get; set; } } public class Income { public int Id { get; set; } public int UserId { get; set; } public decimal Amount { get; set; } public int Year { get; set; } public int Month { get; set; } } public class UserIncomeDto { public string Name { get; set; } public int Year { get; set; } public int Month { get; set; } public decimal Income { get; set; } } public class UserIncomeService { public List<UserIncomeDto> GetUserIncomeDtos(IQueryable<User> users, IQueryable<Income> incomes) { var resultList = (from u in users join newic in (from ic in incomes group ic by new { ic.UserId, ic.Year, ic.Month } into gp select new { gp.Key, InCome = gp.Sum(g => g.Amount) }) on u.Id equals newic.Key.UserId orderby newic.Key select new UserIncomeDto() { Name = u.Name, Year = newic.Key.Year, Month = newic.Key.Month, Income = newic.InCome }).ToList(); return resultList; } }
第7题：
第一种改HTML：
<form action="@Url.Content("~/User/Login")"> <input type="text" placeholder="username" name="username" /> <input type="password" placeholder="password" name="password" /> <input type="submit" value="login" /></form>
