Get values in NotMapped property in model class Entity Framwork Code First using linq

I am using Entity Framework 5‘s Code First in my project and my model looks more or less like this:

public class Category
{
    public int CategoryId { get; set; }
    public string Name { get; set; }

    public virtual Category Parent { get; set; }

    [NotMapped]
    public int Level { get; set; }
}

The generated table contains all columns except the Level column (as expected)

Now, I have a stored procedure which calculates the Level of the Category node in relation to it’s parent.

If I execute the stored procedure in SQL Server Mgmt Studio it returns the columns as specified in my model including the [NotMapped] Level column.

The thing is: the Level column is not filled if I call the stored procedure like this: Context.Database.SqlQuery<TModel>(storedProcedure, parameterArray); where TModel is Category.

Is there any way to ‘re-use’ this Category model?

Answer 1

You clearly say that the property “Level” is not part of your model, therefor it of course won’t be filled by your stored procedure. Why would you expect any else?

The only way would be to parse the result of your sp by hand and create instances of your model class yourself.
