从数据库中获取整数值并将其转换为Enum

Question

I'm all new to Enum types and seems like I can't figure something out in my project. I was asked to use Enum for creating a combobox with pre-defined values. What I did was:

namespace Models
{
    public class LastStatus
    {
        public LastStatus()
        {
        }

        public int ID { get; set; }
        public enum description { inProgress, done, accepted }

        public description desc;
        public int constant { get; set; }

    }
}

And this is my method for converting the DB model to my own model before I use them: (eg add them to a List and then iterate over it to add to the combobox's listitems in aspx.cs side)

private Models.LastStatus ConvertStatusDbToObject(DBModel.myDB.LastStatu status)
        {
            Models.LastStatus statusObject = new Models.LastStatus();
            statusObject.ID = status.ID;
            //statusObject.description = status.description;
            (LastStatus.description)statusObject.desc = (LastStatus.description)status.@const;
            statusObject.constant = status.@const;

            return statusObject;
        }

I get the error on this line:

(LastStatus.description)statusObject.desc = (LastStatus.description)status.@const;

when trying to cast the integer value of the DB Model to my enum type. Isn't desc a property?

Error 23 The left-hand side of an assignment must be a variable, property or indexer

Answer 1

Change (LastStatus.description)statusObject.desc = (LastStatus.description)status.@const; to statusObject.desc = (LastStatus.description)status.@const;

You don't need to cast the property itself!

Answer 2

First , assign integer values to your enum values when declaring the enum. for example:

public enum description { inProgress = 0, done = 1, accepted = 2}

Second , I would recommend against having public fields in your class. change

public description desc;

to

public description desc { get; set; };
