Question

For example, if I want to remove whitespace and trailing commas from a string, I can do this:

String x = "abc,\n";
x.Trim().Trim(new char[] { ',' });

which outputs abc correctly. I could easily wrap this in an extension method, but I’m wondering if there is an in-built way of doing this with a single call to Trim() that I’m missing. I’m used to Python, where I could do this:

import string
x = "abc,\n"

x.strip(string.whitespace + ",")

The documentation states that all Unicode whitespace characters, with a few exceptions, are stripped (see Notes to Callers section), but I’m wondering if there is a way to do this without manually defining a character array in an extension method.

Is there an in-built way to do this? The number of non-whitespace characters I want to strip may vary and won’t necessarily include commas, and I want to remove all whitespace, not just \n.

Using regex makes this simple:

text = Regex.Replace(text, @"^[\s,]+|[\s,]+$", "");

This will match Unicode whitespace characters as well.
