Sorting Japanese text by Katakana in C#

Is it possible to sort a list of Japanese strings by th开发者_高级运维eir Katakana?

Sure you can. If you use CultureInfo, you can make it so it doesn't bother looking for upper/lower-case.

// Create CultureInfo
System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo("ja-JP");
//Create the StringComparer
StringComparer cmp = StringComparer.Create(ci, true);

// Sort your array of string
Array.Sort(myArray, cmp);

You can extend the functinality of the sort to not distinguish between Hiragana and Katakana if you like by doing this:

//Create CultureInfo
System.Globalization.CultureInfo ci = new System.Globalization.CultureInfo("ja-JP");
// Set it so it ignores the kana type
CultureInfoCompare cmp =
new CultureInfoCompare(ci, System.Globalization.CompareOptions.IgnoreKanaType);

//Sort it
Array.Sort(myArray, cmp);

頑張ってください！

Yes, sure you can sort katakana strings by their constituent characters. But this will only work if you are only interested in a subset of the Japanese language. In general Japanese strings are made up of hiragana, katakana and kanji.

If you want basic Japanese language sorting, I would use kakasi to convert kanji to hiragana and then decide how you want to order hiragana and katakana; personally I would be tempted to do あ,　ア,　い,　イ,　う,　ウ, etc.
