实体框架 6 - 使用具有三个表的类（数据库优先）

Question

I'm working with Entity Framework 6.

I have three tables in my database:

• Payments
• Payments_temp
• Payments_error

Payments has these columns:

• Id
• Amount
• Json

The other two tables have the same columns, but with a column called Result.

Can I create a class Payment with all columns and then mapping in the database just the properties I need from a case?

Example:

public class Payment
{
    public string id {get;set;}
    public decimal amount {get;set;}
    public string json {get;set;}
    public string result {get;set;}
}

And in DbContext :

Using(var context = new dbcontext())
{
     paym = new Payment();
     context.Payments.add(paym);

     paym.result = "OK";
     context.Payments_temp.add(paym);
     context.Payments_error.add(paym);
}

If someone knows how do that, I'd really appreciate it

Answer 1

Solved: Convert the clases with json serialize.

In DBContext

  {
     paym = new Payments();
     context.Payments.add(paym);
     paym.result = "OK";
     var serializedPayments = JsonConvert.SerializeObject(paym);
     context.Payments_temp
             .add(JsonConvert.DeserializeObject<Payments_temp>(paym));
     context.Payments_error
             .add(JsonConvert.DeserializeObject<Payments_error>(paym));
}
