Help with List<>..Find()

[=?Utf-8?B?UGhpbA==?=]

I have seen the samples for Find that explain how to use the predicate, but
they are always searching for a pre-defined value. What I don't understand
is how to search for a random value stored in a variable.

For example,

List<intitems;
int val=3;

items.Add(1);
items.Add(2);
items.Add(3);
items.Add(4);

How do I search the list "items" for the value in the variable val?

Thanks,

Phil

One way is to use the .Contains method, but it will only find the
first one. There is also .FindExactStrin g method if the list is a list
of strings.

int b = items.Find(dele gate(int a) { return a == val; });

Or in C# 3:

int b = items.Find(a =a==val);

If you're only concerned with int's..you have an answer already.

If you're interested in this .. in general..I'd suggest:
http://ludwig-stuyck.spaces.l ive.com/Lists/cns!E36D9BA98FC 913B3!296/

Find the C# Generics article (in english) and bookmark and read that.

Try:
items.Select(i =i == val);
or
items.Find(i =i == val);
or
items.Where(i =i == val);

depending on what you mean by Find... refer to

Are you sure you don't want IndexOf instead of Find?
