String Trim Spaces doesn't work

问题

I have a problem with a String. The string is like this:

string something = "  whatever and something else  ";

Now I'm trying to get rid of the spaces at the beginning and at the end like this:

something = something.Trim();

But that didn't work, I also tried this:

something = something.TrimStart();
something = something.TrimEnd();

And this:

something = something.TrimStart(' ');
something = something.TrimEnd(' ');

And this:

int lineLength = line.Length;
string LastCharacter = line.Remove(lineLength - 1);
while (LastCharacter == " ")
{
   line = line.Remove(lineLength - 1);
   lineLength = line.Length;
   LastCharacter = line.Remove(lineLength - 1);
}

The String is Out of a RichTextBox.

Now I think it could be a problem with the Text formatting or something (I'm in Germany).

Thank you in advance, tietze111

回答1:

here's something that will rip out all white space:

 string something = " whatever    ";
 List<char> result = something.ToList();
 result.RemoveAll(c => c == ' ');
 something = new string(result.ToArray());

ok, try this for beginning and end only trims:

  static string TrimWhitespace(string theString)
    {
        theString = "  some kind of string example ";
        theString = theString.TrimEnd();
        theString = theString.TrimStart();
        // MessageBox.Show(theString, "");
        return theString;
    }
