Follow the code below:
List<object> list = new List<object>
{
"abc", // string
1, // int
true // bool
};
TempData["ID"] = list;
The following code can not fetch value:
var data = TempData["ID"];
var test1 = data[0]; //<---- Problema: Não é possível aplicar a indexação com [] a uma expressão do tipo "object"
Is there a solution or is there an easier way?
Since the value of each TempData is of type object there is really no indexer for it. You would have to cast cast to List<object> to actually have a list ready and access its elements.
using System.Collections.Generic;
public class Program {
public static void Main() {
var list = new List<object> {
"abc", // string
1, // int
true // bool
};
var TempData = new Dictionary<string, object>(); //só pra poder testar aqui
TempData["ID"] = list;
var data = TempData["ID"];
var test1 = ((List<object>)data)[0];
}
}
See running on .NET Fiddle . And at Coding Ground . Also I put it in GitHub for future reference .
But I will say that this seems to be a beautiful gambiarra. Almost every time someone creates a list with objects , especially if it has few elements, it's probably doing something wrong. If you need this you probably need a class or tuple and not a list. This becomes clearer with the comments used.
I'm already in doubt whether to use TempData .
