CaseInsensitive Comparer weirdness

Shouldn't the CaseInsensitive Comparer sort case-insensitively?

The following code prints out 'AZaz', which indicates a case-sensitive sort.
What do I need to do to perform a case-insensitive sort ('AaZz')?

char[] chars = new char[] { 'A', 'z', 'a', 'Z' };
string sorted = "";

Array.Sort(char s, new System.Collecti ons.CaseInsensi tiveComparer()) ;

for (int i = 0; i < chars.Length; i++)
{
sorted += chars[i];
}

Console.WriteLi ne(sorted);

It should, and it does - for strings. It doesn't compare characters. If
you change your sample to use strings instead of chars, it works fine.

Ah, thanks for clearing that up!

Hi, I'm experiencing some weirdness in a program, when subtracting 2 (double)'s which should result in 0, but instead it returns -1.11022e-16. It looks to me that changing the double x_step decleration to unsigned type, might help, but the compiler complains when i try that. Any ideas ? #include <iostream>

Hi group, I'm experiencing some extreme weirdness over the last week with IIS related to it's Mappings and how .NET is behaving. I can't explain the behavior as it seems very random. Our app has about 50 file extensions that we map in IIS and handle in our HTTPHandler to catch the reference and then lookup the correct content from a database. In addition, we do some magic in a HTTPModule to rewrite paths for file types we don't...

New warning in .net 2.0... The cumbersome, and difficult to remember case-insensitive comparer declaration for the hashtable has been deprecated... It tells me to use IEqualityComparer instead.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
