EntityFramework 学习 一 枚举

1. Convert an existing property to Enum:

 

 

 

 

 

 using (var ctx = new SchoolDBEntities())
    {
        Teacher tchr = new Teacher();
        tchr.TeacherName = "New Teacher";

        //assign enum value
        tchr.TeacherType = TeacherType.Permanent;

        ctx.Teachers.Add(tchr);

        ctx.SaveChanges();
    }

 

 

 2. Add New Enum from Designer:

 

 3. If you already have Enum type created in your code, then you can use that as a data type of any entity property.
