var worker = from w in db.Distributions

dataGridView1.DataSource = worker.ToList();
//I'm tired for this try various way but still now i face this error..System.NotSupportedException: 'The specified type member 'Date' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.' **Where HowManyDays is string type variable. How can solve it? I want to see:Example - "10 days ago" this type answer.
Try the following solution to get the date difference of two dates:
var days = from items in Vals
select new
{
days = items.maxdate - items.mindate
};
foreach (var day in days)
{
Console.WriteLine(day.days.TotalDays);
}
According to that error message, linq thinks that Date
property needs to be converted to an SQL statement.
Try declaring DateTime.Now.Date
earlier on a separate line before the linq statement, like var nowDate = DateTime.Now.Date
, then reference nowDate
in the linq statement instead of DateTime.Now.Date
