C#中去除字符串空格的三种方法

static void Main()
        {
            //demo1     除去空格，提取出各个单词
            string s = "a b c";
            string[] word = s.Split(new char[] { ' ' });
            foreach (string temp in word)
                Console.WriteLine(temp);

            //demo2     直接去除所有空格
            s=s.Replace(" ","");
            Console.WriteLine(s);

            //demo3     去掉首尾空格
            s = " aaa ";
            s = s.Trim();
            Console.WriteLine(s);
        }
