In JavaScript it is easy to create an object with new properties.
var obj = {
"propriedade1" : "valor",
"propriedade2" : "valor"
}
Is it possible to do something similar in C #?
var lista = new List<Object>();
foreach (var item in umaOutraList)
{
lista.Add(new Object()
{
nome = item.Nome //Essa linha não funfa.
});
}
Current responses do not exactly simulate what happens with JS. It may even achieve a similar (and not the same) result, but in a very different way. So it correctly simulates:
using static System.Console;
using System.Dynamic;
public class Program {
public static void Main() {
dynamic obj = new ExpandoObject();
obj.propriedade1 = "valor1";
obj.propriedade2 = "valor2";
WriteLine(obj.propriedade1);
WriteLine(obj.propriedade2);
}
}
See working on dotNetFiddle .
ExpandoObject() documentation .
In this way you can add and remove members in the object as you can in JS. You can manipulate everything dynamically as it is in JS, with a standard language syntax. So the object is created without having a class as a template, but it behaves as if it were a normal .Net object.
It may not be necessary for the AP, but the premise of the question indicates this.
If this is really necessary in your code without actually having class , then you can use dynamic of C # instead of object , doing something like this:
IList<dynamic> list = new List<dynamic>();
list.Add(new {
nome = "Fernando",
idade = 26,
});
Basically this is Anonymous Type .
Example:
var umaOutraList = new List<String>();
umaOutraList.Add("1");
umaOutraList.Add("2");
var novaLista = umaOutraList.Select(x => new {
Nome = x
});
foreach (var item in novaLista)
{
Console.WriteLine(item.Nome);
}

Using an anonymous object should work, just use new { nome = "" } instead of using new Object { nome = "" } .
Using dynamic as @Fernando suggested in his response should also work.
