C#的实现：

public class Solution {
    public int LengthOfLastWord(string s) {
        s = s.Trim();
            if (s.Length == 0 || s.Trim().Length == 0)
            {
                return 0;
            }
            var len = s.Length;

            var list = s.Split(' ');
            var word = list[list.Length - 1];
            return word.Length;
    }
}

补充Java的实现：

class Solution {
    public int lengthOfLastWord(String s) {
        s = s.trim();
        int n = s.length();
        if(n == 0){
            return 0;
        }
        String[] array = s.split(" ");
        int len = array.length;
        return array[len-1].length();
    }
}
