Removing case sensitivity

Question

My program has a search and update function. But it will only find a match if the user types in Jane Doe not jane doe. ATM my programs retrieving user input, converting into char array and changing the first letter of each word but this doesn't seem to work either. This is the code I'm using..

Any help on how to go about this would be great and why my method of conversion isn't working :)

Not migrating to a more appropriate site as this question seems to be too basic. — Daniel Beck, Oct 07 '12 at 10:32

In C#, strings have a number of comparison functions, such as the Equals function, that have case insensitive overloads.

Another possibility you might look into, if the array you're searching in is sorted, is the Array.BinarySearch<string> function.

Are you able to explain why my method of comparison isn't working? – Jane Oct 07 '12 at 07:49
You didn't specify your method of comparison. Can you post the code? And the real code this time? – Mr Lister Oct 07 '12 at 08:33
Edited my post to include my if compare method – Jane Oct 07 '12 at 08:37
The inserting into array code segment is in a different method etc – Jane Oct 07 '12 at 08:39
You're using == in there. But like I said, you should use Equals. Specifically the one with the StringComparison parameter. – Mr Lister Oct 07 '12 at 08:40
I've never used that before... if (contPeople[i].name equals userContChange)? – Jane Oct 07 '12 at 08:43
It's a function. See the MSDN page. if (contPeople[i].name.Equals(userContChange, StringComparison.InvariantCultureIgnoreCase)) – Mr Lister Oct 07 '12 at 08:49
