hi,

I have a number column with possible value null, 0, 1.

How shall I define the object and the mapping so that when read data from the DB, I can know it's null or 0?

well i'm not sure if you are using the "number" as a boolean, but if you are you could define it as a Nullables.NullableBoolean.

Otherwise there are NullableInt16, NullableInt32 and NullableInt64.

Code:

using Nullables;

public class MyClass {
  private NullableBoolean myNumber;

  public NullableBoolean MyNumber {
    get { return this.myNumber; }
    set { this.myNumber = value; }
  }
}
