捷克语中的c＃排序数组

Question

I have problem sorting an array with Czech names. I have such array:

    var myList = new[]
    {
        "Čas revize", "Datum kalibrace", "Chybové kódy"
    };

and try to sort it like this:

CultureInfo culture = new CultureInfo("cs-CZ");
var result = myList.OrderBy(x => x, StringComparer.Create(culture, true));

So I expect that the data will be sorted as follows:

"Čas revize", "Chybové kódy", "Datum kalibrace"

But it end it up in different order:

"Čas revize", "Datum kalibrace", "Chybové kódy"

Answer 1

Interesting question. If you read the documentation

In Czech - Czech Republic culture, "ch" is a single character that is greater than "d". However, in English - United States culture, "ch" consists of two characters, and "c" is less than "d".

The Czech alphabet is ordered

A Á BC Č D Ď E É Ě FGH Ch I Í JKLMN Ň O Ó PQR Ř S Š T Ť U Ú Ů VWXY Ý Z Ž

So the ordering of your array is correct.

Answer 2

I just tested this:

List<string> myList = new List<string> { "Čas revize", "Datum kalibrace", "Chybové kódy", "óóó", "ČČČ", "aaa", "ééé", "èèè", "êêê", "fff", "Code" };
CultureInfo culture = new CultureInfo ("cs-CZ");
List<string> result = myList.OrderBy (x => x, StringComparer.Create (culture, true)).ToList ();

And got the result:

aaa Code 'Čas revize' ČČČ 'Datum kalibrace' ééé èèè êêê fff Chybové kódy óóó

Then I tested this:

List<string> myList = new List<string> { "Čas revize", "Datum kalibrace", "Chybové kódy", "óóó", "ČČČ", "aaa", "ééé", "èèè", "êêê", "fff", "Code" };
List<string> result = myList.OrderBy (j => j).ToList ();

And got this result:

aaa 'Čas revize' ČČČ 'Chybové kódy' Code 'Datum kalibrace' ééé èèè êêê fff óóó

It looks like the 'C' in Chybové is a different character than a normal 'C'. Or that 'Ch' or 'Chy' may have it's own position in your alphabet. But without the CultureInfo, it seems to treat it correctly regardless of special characters.
