在数据库MVC4 asp.net中显示新表

Question

我很无聊，我不知道为什么我的数据库显示在数据库中的deafult连接中，我正在使用razor技术在C＃MVC4 asp.net中编程，

这是我的UserAccountContext

public class UserAccountContext : DbContext
{
    public UserAccountContext()
        : base("DefaultConnection")
    {
    }

    public DbSet<UserAccount> UserAccounts { get; set; }

    // Methods...
    public DbSet<UserProfile> UserProfiles { get; set; }
    // Methods...

    public IQueryable<UserAccount> GetAll()
    {
        IQueryable<UserAccount> query = this.UserAccounts;

        return query;
    }

    public UserAccount GetSingle(string _UserName)
    {
        UserAccount Query = this.GetAll().FirstOrDefault(x => x.UserName == _UserName);

        return Query;
    }

    public void Save(UserAccount _UserAccount)
    {
        if (_UserAccount.ID == 0)
        {
            this.UserAccounts.Add(_UserAccount);
            this.SaveChanges();
        }
        else
        {
            this.SaveChanges();
        }
    }
}

这是我的UserAccount模型

public class UserAccount
{
    // Attributes turns into fields in the database
    // These attributes persist in the database
    [Key]
    public int ID { get; set; }
    public int UserId { get; set; }
    public string UserName { get; set; }
    public string WhoVoted { get; set; }
    public double NumberOfVotes { get; set; }

    // The following attributes will not persist in the DB
    public string UserErrorMessage = string.Empty; // Volatile Variable

    // Methods...

    public UserAccount() { } //Constructor... This is needed to create the DB Table

    public UserAccount(int _UserId, string _UserName) // Other Constructor
    {
        this.ID = 0;
        this.UserId = _UserId;
        this.UserName = _UserName;
        this.NumberOfVotes = 0.0;
        this.WhoVoted = string.Empty;
    }
}

我拥有一切，我不知道如何处理数据库，寻求任何帮助。提前谢谢！
