c#.NET Checking for an element in an array case insensitive

[rhitam30111985]

Hi all ,


I found a way to check for an element in a c# array here :

http://www.dotnettoad.com/index.php?/archives/10-Array.Contains.html

But this is case sensitive search. Is there a way to do the same thing by ignoring case ?


Regards ,

I'm lazy... I just do all my comparrisons using the .ToLower() method

String bob = "This is a Mixed Case String";
if (bob.ToLower() contains "mixed")
{
     // Jump for joy
}

C# is case-sensitive so you have to make sure that the value you are comparing should be the same, that means you need to use either to lower or to upper, depending on the value you want to compare.

        public string[] Contains(IEnumerable<string> array, string val)
        {
            return (new List<string>(array)).FindAll(s => s.ToLower() == val.ToLower()).ToArray();
        }

Or

        public string Contains(IEnumerable<string> array, string val)
        {
            return (new List<string>(array)).Find(s => s.ToLower() == val.ToLower());
        }

That's what I use at least. :)
