C # string Trim not working, weird problem

Question

I have a line like this:

string val = 555*324-000

now I need to remove the * and - characters, so I use this code ( based on MSDN )

char[] CharsToDelete = {'*', '(', ')', '-', '[', ']', '{', '}' };
string result = val.Trim(CharsToDelete);

but the string remains unchanged. What reason?

Answer 1

Trim ... Removes all leading and trailing occurrences of the character set specified in the array from the current String object. Instead, you should use a replacement method.

Answer 2

Since Trim () will delete any character in CharsToDelete at the beginning and end of the line.

You should use the val.Replace () function.

Answer 3

:

string val = 555*324-000
char[] CharsToDelete = {'*', '(', ')', '-', '[', ']', '{', '}' };

foreach (char c in CharsToDelete)
{
  val = val.Replace(c, '');
}
