C#小白学习笔记（6）字符串处理1

namespace String01
{
    class Program
    {
        static void Main(string[] args)
        {
            char[] ch1 = { 'a', 'B', 'F' };

            string str = "aBcDeFg";
            Console.WriteLine(str.ToUpper());// Console.WriteLine(str.ToLower());
            Console.WriteLine(str.Trim(ch1));//移除字符串两端的指定字符

            string str1 = "abc";
            Console.WriteLine(str1.PadLeft(10));//左侧填充空格实现右对齐
            Console.WriteLine(str1.IndexOf('c'));

            string str2 = "defg";
            Console.WriteLine(str2.PadLeft(10, '*'));

            string.Equals(str1, str2); //bool b = str1.Equals(str2);

            foreach (char ch in str) //循环输出字符串str中的字符
            {
                Console.WriteLine(ch);
            }
            //char[] ch = str.ToCharArray(); //将字符串复制到字符数组中
            int len = str.Length;
            Console.WriteLine(len);
            Console.ReadKey();
        }
    }
}

运行结果如下所示：
