[C#] 4 ways to remove "\r" or "\n" or "\t" new line or line break and tab characters from a string?

If you have a string, like this:

string str = "Line 1\n   Tab it.\t Break.\n'

How to remove breakline or tab in this string? 

So you can using some methods:

Method 1: quick to code

string newstr = Regex.Replace(str, @"\t|\n|\r", ""); // \t is tab, \n and \r is new line

Method 2: for New line only

string newstr = str.Replace(Environment.NewLine, "");

Method 3: Easy to code

str = str.Replace("\n", String.Empty);
str = str.Replace("\r", String.Empty);
str = str.Replace("\t", String.Empty);

Method 4: For speed and low memory, because is StringBuilder best!

var sb = new StringBuilder(s.Length);

foreach (char i in str)
    if (i != '\n' && i != '\r' && i != '\t')
        sb.Append(i);

str = sb.ToString();
