简单的EF Code First

创建对象类

public class Student
{
public int ID{ get; set; }
public string Name{ get; set; }
public int Age { get; set; }
public string Sex{ get; set; }
}

添加数据库连接配置

<connectionStrings>
<add name="connstr" connectionString="server=.;database=EFCodeFirstDB;uid=sa;pwd=123456" providerName="System.Data.SqlClient"/>
</connectionStrings>

创建继承自DbContext的上下文类

public class DbContextClass:DbContext
{
public DbContextClass()
:base("connstr")
{}
public DbSet<Student> Students { get; set; }
}

自动创建数据库

Student stu = new Student()
{
ID = 1,
Name = "11",
Age = 20,
Sex = "男"
};
using(var db=new DbContextClass())
{
db.Students.Add(stu);
db.SaveChanges();
}
