I am new to this. I am getting data from database and storing each tuple in the following way to form a list:
var dataFromDB = (
from to in _context.Time
join user in _context.Users
on to.UserId equals user.Id
select new Events
{
userId = user.Id,
title = user.FirstName[0] + " " + user.LastName[0],
...
}).ToList();
I want title
to have the initials from FirstName
and LastName
where FirstName
and LastName
are coming from the Users
table. Example, if the FirstName
is John
and LastName
is Doe
, then I want title
to have JD
.
Events
class is in the following way:
public class CalendarEvents
{
public string userId { get; set; }
public string title { get; set; }
...
}
Edit 1.0
On running the code, I am getting the following exception:
An exception of type 'System.ArgumentNullException' occurred in mscorlib.dll but was not handled in user code.
Additional information: Value cannot be null.
Edit 2.0
FirstName
and LastName
is in the following way:
[Required(ErrorMessage = "Please enter first name")]
[Display(Name = "First Name")]
public string FirstName { get; set; }
[Required(ErrorMessage = "Please enter last name")]
[Display(Name = "Last Name")]
public string LastName { get; set; }
If you want the first initial and second initial I would suggest:
title = user.FirstName.FirstOrDefault().ToString()
+ user.LastName.FirstOrDefault().ToString(),
Since, user.FirstName.FirstOrDefault()
returns the first character from the FirstName
.
