发送不需要的字符到数组末尾

Question

Let's say we have a string

String data = "<span> 0397]);}}:;)]</span>";

Then we send that into an char array

Char[] charData = data.ToCharArray();

How could I go trough this data and replace all unwanted data to the end of the array but move all data left one from the current char that has been moved to make room at the end for the unwanted data.

Char[] sendToEnd = { ';', ')', '}', ']' };

I have tried a loop but it causes an infinite loop when it loops over the already swapped data.

In the end the string data should be

"<span> 0397</span>]);}}:;)]"

Answer 1

var str = new String(data.Where(c => !sendToEnd.Contains(c))
                         .Concat(data.Where(c => sendToEnd.Contains(c)))
                         .ToArray());

Also declaring sendToEnd as

var sendToEnd = new HashSet<char>(new char[] { ';', ')', '}', ']' });

can give a better performance

Answer 2

与其将字符最初移动到末尾，不如将它们移动到另一个数组并将这些数组连接起来以形成最终的字符串。
