Question

我知道没有N个具有相同标题的解决方案，并且经过3天无休止的运行，所有这些我都必须在此处发布。

我有一个像这样的UserDetailDAC.cs：-

public UserDetails ValidateUserAdmin(string Usrname, string pwd)
    {
        using (var db = new HostelManagementContext())
        {
            //IEnumerable<UserDetails> linq;
            //string query = "SELECT* FROM UserDetails WHERE UserName ='" + Usrname + "' COLLATE SQL_Latin1_General_CP1_CS_AS AND UserPwd = '" + pwd + "' COLLATE SQL_Latin1_General_CP1_CS_AS";
            //linq = db.Database.SqlQuery<UserDetails>(query);
            //return linq.FirstOrDefault();
            return db.Set<UserDetails>().Where(x => x.UserName == Usrname && x.UserPwd == pwd).FirstOrDefault();
        }
    }

和我的HostelManagementContext.cs一样：-

 public HostelManagementContext() : base("ConnectionString")
    {
        Database.SetInitializer(new MigrateDatabaseToLatestVersion<HostelManagementContext, HostelModel.Migrations.Configuration>("ConnectionString"));
        //Database.SetInitializer<HostelManagementContext>(new DropCreateDatabaseIfModelChanges<HostelManagementContext>());
    }
    public DbSet<CandidateHostelBookingMapping> CandidateHostelBookingMappings { get; set; }
public DbSet<UserDetails> UserDetails { get; set; }

现在，当我尝试运行此命令时，出现以下错误：-

Cannot find the object "CandidateHostelBookingMappings" because it does not exist or you do not have permissions.

这是实体框架代码优先方法。请随时询问其他详细信息

///您是否使用包迁移通过程序包管理器控制台创建数据库和表？

enable-migrations -ContextTypeName HostelManagementContext 
add-migration -ConfigurationTypeName -----
update-database -ProjectName

找不到对象“ TABLE”，因为它不存在或您没有权限
