I am trying to use the following; I have an array with bunch of values
in it. I am trying to find a value that contains part of the string I
am passing
eg
string[] array = {"help","Csh arp rocks"}
if (array.Contains <string>("Cshar p"))
{
//here I want to get the actual string like "Csharp rocks"
string str = array.First<str ing>(); //Here there is a way, I can
check if the string has the value using lambda expression, not sure
how.
}
Could someone help?
Thanks, 6 7682

You can avoid the "contains" bit to start with by using FirstOrDefault:
string first = array.FirstOrDe fault(x =x.Contains("Cs harp"));
if (first != null)
{
...
}

Hi,
myStringList.Fi nd(delegate(str ing item) { return
item.Contains(" MyStr"); });
Love generics :)
If you are in 3.5 you could replace it with a Lambda expression

quick question, what does (x=>x.Contains( "Csharp")) means?
I know that, x is each element from the collection and it returns the
string of x. So does it mean, foreach element in the array first the
first element which contains the requested match?
x=>x.Contains() what does it do? It is evaluating to a bool and where
is the return here?
Thanks you very much?

Sort of, yes.

It's a lambda expression. I don't have time to go into lambda
expressions in detail right now, but hopefully you can find out a fair
amount about them just by searching with the right name.
My bluffer's guide gives *slightly* more detail: http://csharpindepth.com/Articles/Ge...ersGuide3.aspx

If you want *lots* of detail, look at chapter 9 in my book - click on
the image on the left hand side of the page linked above.

Hi all
I want to create a std::vector that goes from 1 to n instead of 0 to n-1.
The only change this will have is in loops and when the vector returns
positions of elements etc. I am calling this uovec at the moment (for
Unit-Offset VECtor). I want the class to respond correctly to all usage of
STL containers and algorithms so that it is a transparent replacement for
std:vector.
The options seems to be:

what about setting (or changing) the pixel values back onto
