c# – 实体框架创建与模型中每个类相对应的单独数据库

public class Employee 
{
    [Key] public int EmpId { get; set; } // < Can I make a suggestion here
                                         // and suggest you use Id rather than
                                         // EmpId?  It looks better referring to 
                                         // employee.Id rather than employee.EmpId
    [Required] public string Fullname { get; set; }
    ...
}

public class AnotherClass
{
    ...
}

然后在上下文中列出所有模型：

public MyDbContext : DbContext
{
    public DbSet<Employee> Employees { get; set; }
    public DbSet<AnotherClass> AnotherClasses { get; set; }
}

您可能还希望使用Context中的构造函数指定连接字符串名称：

public MyDbContext() : base("ConnectionString") {  }

所有模型都在同一个环境中运行非常重要.

使用上下文

var context = new MyDbContext();
var employees = context.employees.ToList(); // I prefer storing the data as an IList

这告诉EF查询数据库并将数据存储在employees变量中.
