Is there a way in c# or VB to dynamically call variables from a loop? Instead of going one by one of every variable?
Imagine the following example,I want to set dog1Legs, dog2Legs, dog3Legs, Is there a way how to call them from a loop?
String dog1Legs;
String dog2Legs;
String dog3Legs;
for(int i=1; i<4; i++)
{
dog(i)Legs = "test";
}
You need no write the code as
String dog1Legs;
String dog2Legs;
String dog3Legs;
for (int i=1; i<4; i++)
{
FieldInfo z = this.GetType().GetField("dog" + i + "Legs");
object p = (object)this;
z.SetValue(p, "test");
}
You should use an array or list. E.g.
var dogLegs = new String[3];
for(int i=0; i<dogLegs.Length; i++)
{
dogLegs[i] = "test";
}
Or making a Dog class might make sense, e.g.
void Main()
{
var dogs = new List<Dog>();
dogs.Add(new Dog { Name = "Max", Breed = "Mutt", Legs = 4 });
foreach (var dog in dogs)
{
// do something
}
}
class Dog
{
public int Legs { get; set; }
public string Breed { get; set; }
public string Name { get; set; }
}
No, you can't do this. Typical solution is dictionary:
Dictionary<String, String> dogs = new Dictionary<String, String>();
dogs.Add("dog1Legs", null);
dogs.Add("dog2Legs", null);
dogs.Add("dog3Legs", null);
for(int i = 1; i < 4; i++) {
dogs["dogs" + i.ToString() + "Legs"] = "test";
}
