i want to create a simple program that i have a array of strings and for each string i want to check if it contains specified character, i want to remove it.first of all i replace the specified characters with space and when i tried to trim the spaces it doesn't work Here it is my code
char[] arr = new char[] {' '};
for (int i = 0; i < words.Length; i++)
{
words[i] = words[i].Replace('0', ' ');
words[i] = words[i].Trim(arr);
}
If you want to remove all spaces, instead of words[i] = words[i].Trim(arr);, you can use:
words[i] = words[i].Replace(" ", string.Empty);
Personally, I would do this for your first removal (0) as well:
words[i] = words[i].Replace("0", string.Empty); // Remove all "0" characters
words[i] = words[i].Replace(" ", string.Empty); // Remove all spaces
Or, even:
words[i] = words[i].Replace("0", string.Empty).Replace(" ", string.Empty);
Trim() only removes leading and trailing spaces. It won't remove spaces in the middle of a string. There's really no need to do all that work though. You can make a single call to Replace() by calling the appropriate overload:
for(int i = 0; i < words.Length; i++)
words[i] = words[i].Replace("0", "");
and for people who like one-liners:
words = words.Select(i => i.Replace("0", "").Replace(" ", "")).ToArray();
