List.Exists method

[Tarscher]

Hi all,

I have a list of integers and simply want to check if a number exists
in that list. In the manual I found the List.Exists method but this
apparently only works for constants values via a predicate? Am I wrong
here?

What I want to do
List<int> id = new List<int>();
...
populate list
...
id.Exists(10);
id.Exists(12);
....

Someone can help me out?

Thanks
Stijn

use List.Contains or List.IndexOf

Run this:

List<int> list=new List<int>();
for (int i=0;i<50;i++) {
list.Add(i);
}
int seekMe=23;
if (list.Contains(seekMe)) {
Console.WriteLine("Yep, there is a {0} in the list", seekMe);
} else {
Console.WriteLine("Nope, there isn't a {0} in the list", seekMe);
}

Hth.
