Check three column value and update to another column through linq

Hello All,

I want to write linq query where i have to check "Task " column contain expires then check “date” column if date is in the range of 15 days start from today. (today is 06/11/2021 to 06/20/2021). then check in “Status” column if it is null then update “status” column to ‘present’. else remaining data are same as it is. Please help on these. I have tried to write multiple query to find result but i am not getting exact result.

Data.xlsx (8.7 KB)

You meant to say range is 10 days??

@pankajj - For the time being I have assumed the Range is 10 sine you mentioned between 6/11 and 6/20 I have derived the below solution…


Read Range - Check the Preserve Format and Save the output as dt


dt.AsEnumerable.Select(Function(r) dt.Clone.LoadDataRow({r("ID"),r("Task"),r("Date"),if(r("Task").ToString.Contains("Expires") AndAlso (Datetime.Parse(r("Date").ToString) >= Cdate(Now.tostring("M/dd/yyyy")) and Datetime.Parse(r("Date").ToString) <= Cdate(Now.AddDays(10).tostring("M/dd/yyyy")) AndAlso String.IsNullOrEmpty(r("Status").ToString)),"Present",r("Status")),r("")},False)).CopyToDataTable

My Input(Purposely added Not Null in the status column to check the condition)



Hope this helps…
