I want to know if I can access an item of my List and assign it to a textbox?
public static List<Product> detailsList = new List<Product>();
Product is my class generated by using LINQ to SQL with fields Name,Code,Details i.e my List contains the items(Name,Code,Details). I want to access the value of the item Details from the list and assign it to a textbox . Something like:
txtDetails.Text = detailsList.Details.ToString()
If you want the details of 1 item:
var detailsList = new List<TaskDto>();
// add items
// this if you know the corect index
txtDetails.Text = detailsList[0].Details;
// if you need to query for example for the item with the correct Id
txtDetails.Text = detailsList.FirstOrDefault(p => p.Id == 1).Details;
You can select first or default from the item based on some criteria, like the name.
public static List<Product> detailsList = new List<Product>();
var prod = detailsList.FirstOrDefault(p => p.Name == 'Ana');
if(prod != null) {
txtDetails.Text = prod.Details;
}
For all items:
var joinSymbol = ", ";
txtDetails.Text = string.Join(joinSymbol, detailsList.Select(detail => detail.Details));
For first item if Details:
txtDetails.Text = detailsList.FirstOrDefault()?.Details ?? string.Empty;
use string.Join() function.
txtDetails.Text = string.Join(",", detailsList.Select(e => e.Details)).ToList());
string.Join takes parameters in reversed order.
