An implementation of IComparer<string> that respects integers embedded within strings and sorts them in the way that a human would expect.
// These strings are ordered according to StringComparer.Ordinal and friends
var strings = new[]
{
"Item100",
"Item20",
"Item3"
};
// Re-order to the 'natural' order, considering integers within strings
Array.Sort(strings, NaturalStringComparer.Ordinal);
// Now the items are:
//
// "Item3"
// "Item20"
// "Item100"I originally posted this code on Stack Overflow. It feels like it could be useful as its own NuGet package.

The implementation has good performance, with no heap allocation during comparison.
