List operations getting a list's index

List operations getting a list's index

I have a class in my Windows application like so:
public class Pets
{
String Name {get;set;}
int Amount {get;set;}
}
In one of my other classes i made a List of that class like so.
List<Pets> myPets = new List<Pets>();
myPets.Add(new Pets{ Name = "Fish", Amount = 8});
myPets.Add(new Pets{ Name = "Dogs", Amount = 2});
myPets.Add(new Pets{ Name = "Cats", Amount = 2});
Is there a way i can get the Index of the Pets whos Name = "Fish"?
I realize i can do this
int pos = 0;
for(int x = 0; x<myPets.Count;x++)
{
if( myPets[x].Name == "Fish")
{
pos = x;
}
}
But in the case that i have ALOT of items in myPets it would take long to
loop through them to find the one i am looking for. Is there another way
to complete the task above. That would make my application run quicker? In
the case that myPets has a lot of items in it.
