Default Value For A Blank Field

Hi Experts!

Thanks for reading this.

So, using LinqToExcel to pull data into a Model:

string sFileName = @"C:\Working Directory\Product.xlsx";

var excel = new ExcelQueryFactory(sFileName);
excel.DatabaseEngine = LinqToExcel.Domain.DatabaseEngine.Jet;

var per = from x in excel.Worksheet<Model1>("Product")
            select x;

Open in new window

    public class Model1
    {
        public string PRODUCT { get; set; }
        public string STARTDATE { get; set; }
        public string ENDDATE { get; set; }
    }

Open in new window

In per (Model1) how would you update the blank value in the End Date to a default value say 20781231?

The content of Product looks like this (with Blank End Date):

TIA!

Hi allanau20;

All that would be needed is to modify your Model1 class as follows.

public class Model1
{
    public string PRODUCT { get; set; }
    public string STARTDATE { get; set; }
    private string _Enddate; 
    public string ENDDATE
    {
        get { return _Enddate; }
        set
        {
            if(String.IsNullOrEmpty(value))
                _Enddate = "20781231";
            else
                _Enddate = value;
        }
    }
}

Hi FernandoSoto,

When I look at the per (Model1) we can see that if the End Date is blank it will default to 20781231. So, it satisfied the requirement.

However, this question is a an extension of the previous question, in prods (Model1) for Product = 0002-0800 the End Date = 20340201 was selected. It should have been 20781231.
For the other Product (0002-1407, 0002-1975, 0002-3004, 0002-3227) it selected the correct End Date (latest end date for that product).

I'll open up another question.

Thanks again for your help!
