I'm trying to convert this long JS regex to C#.

The JS code below gives 29 items in an array starting from ["","常","","に","","最新","、","最高"...]

var keywords = /( |[a-zA-Z0-9]+.[a-z]2,|[一-龠々〆ヵヶゝ]+|[ぁ-んゝ]+|[ァ-ヴー]+|[a-zA-Z0-9]+|[ａ-ｚＡ-Ｚ０-９]+)/g;
var source = '常に最新、最高のモバイル。Androidを開発した同じチームから。';
var result = source.split(keywords);

But the C# code below gives a non-splitted single item in string.

var keywords = @"/( |[a-zA-Z0-9]+.[a-z]2,|[一-龠々〆ヵヶゝ]+|[ぁ-んゝ]+|[ァ-ヴー]+|[a-zA-Z0-9]+|[ａ-ｚＡ-Ｚ０-９]+)/g";
var source = @"常に最新、最高のモバイル。Androidを開発した同じチームから。";
var result = Regex.Split(source, keywords);

Many questions in Stack Overflow are covering relatively simple expressions only, so I cannot find my mistakes.

What am I missing?

Your RegEx is wrong, you should not start and end with '/' or '/g' You specify a string in the constructor, not a JavaScript Regex (with '/ /' syntax.). That's a Javascript syntax.

Actually the same applies to JavaScript when you use a string constructor like this:

var regex = new RegExp('//'); // This will match 2 slashes
