c# - LINQ to SQL - Checking the field length -

i getting rows access db. need check fields length. got work, problem if field comes null. check fails. how made check length (array[0] column name checked), , works:

results = query.where(p => p.field<string>(array[0]).length > 10); 

now problem if field null. screen shot displays field coming empty , fails check. field number 25.

how can make ignore nulls , still check length?

you can try avoid nulls.

results = query.where(p =>      !string.isnullorempty(p.field<string>(array[0]))      &&  p.field<string>(array[0]).length > 10);
