I know you can do this. But I can not seem to find it.
How do I get a function to accept a variable number of parameters of the same type, similar to an array?
So I can simply call it like this:
UIMostra("Localização", "Informações Gerais", "Acessos")
instead of calling by creating an array (polluted):
UIMostra(new string[]{"Localização", "Informações Gerais", "Acessos"})
Use the keyword params , which allows you to indicate that an array argument will receive a parameter list without explicitly passing an array.
public void MeuMetodo(params object[] meusParametros)
{
// usar o array de parametros
}
The argument that receives the keyword params should be the last one, and should be declared along with an array type.
To pass a list of integers, for example:
public void MetodoComListaDeInteiros(params int[] arrayInteiros)
{
// faça algo com os inteiros... e.g. iterar eles num laço for, e mostrar na tela
foreach (var eachNum in arrayInteiros)
Console.WriteLine(eachNum);
}
and then call it like this:
MetodoComListaDeInteiros(1, 2, 5, 10);
Every method that accepts a list also accepts an array, so the same method above can also be called like this:
MetodoComListaDeInteiros(new int[] { 1, 2, 5, 10 });
It is possible to improve the first example described by Miguel Angelo. Instead of using object type variable, you can achieve the same result, but with better use of resources using Generics . It would look like this:
Method declaration
public void MeuMetodo<T>(params T[] meusParametros)
{
foreach(T parametro in meusParametros)
//restante do código
}
Usage:
public class Cliente
{
public Cliente(int id, String nome)
{
this.Id = id;
this.Nome = nome;
}
public int Id { get; set; }
public String Nome { get; set; }
}
Cliente cli1 = new Cliente(1, "João");
Cliente cli2 = new Cliente(2, "Maria");
Cliente cli3 = new Cliente(3, "José");
MeuMetodo<Cliente>(cli1, cli2, cli3);
