You can use Replace method to replace '\t' with empty string. Like:
String str1 = "Great punctuation: keep only words, skip all punctuation.\tAlso - skip all spaces and tab characters!";
str1 = str1.Replace("\t", "");
char[] spearator = { ',', ' ', '!', ':', ';', '.', '-' };
String[] strlist1 = str1.Split(spearator, StringSplitOptions.RemoveEmptyEntries);
foreach (String x in strlist1)
{
Console.WriteLine(x);
}
Output:
Great
punctuation
keep
only
words
skip
all
punctuation
Also
skip
all
spaces
and
tab
characters
