I am trying to remove whitespaces from string but it is not working

string status = "                                       18820 Pacific Coast Highway

                                        Malibu, CA 90265";
        string status1 = status.Trim();
        Console.Write(status1);

The above code is not working

Expected Output:

18820 Pacific Coast Highway Malibu, CA 90265

回答1:

Trim() only works at the start and end of a string. This should work:

string status1 = Regex.Replace(status,@"\s+"," ").Trim();

回答2:

Trim removes leading and trailing symbols (spaces by default). Use Regular expression instead.

RegEx.Replace(status, "\s+", " ").Trim();

string status = "                                       18820 Pacific Coast Highway

                                        Malibu, CA 90265";
        string status1 = status.Trim();
        Console.Write(status1);


status = status .Replace(" ", "");

But the above code will remove all the whitespaces.

If you want to have whitespace at the end of everyword, then use foreach as mentioned in this link
