字串格式化

             Console.WriteLine(string.Format("金額顯示：{0:C}", 368));
             Console.WriteLine(string.Format("科學計數法顯示：{0:E}", 12000000.1));
             Console.WriteLine(string.Format("分割數字顯示：{0:N0}", 123456789));
             Console.WriteLine(string
 
.Format("Π取兩位小數顯示：{0:F2}", Math.PI));
             Console.WriteLine(string.Format("16進位制顯示：{0:X4}", 33));
             Console.WriteLine(string.Format("百分比顯示：{0:P}", 0.96));

日期格式化

            DateTime strDate = DateTime.Now;
            Console.WriteLine(string.Format("短日期格式：{0:d}"
 
, strDate));
            Console.WriteLine(string.Format("長日期格式：{0:D}", strDate));
            Console.WriteLine(string.Format("完整日期格式：{0:f}", strDate));
            Console.WriteLine(string.Format("短時間格式：{0:t}", strDate));
            Console.WriteLine(string.Format("長時間格式：{0:T}"
 
, strDate));
            Console.WriteLine(string.Format("月日期格式：{0:M}", strDate));
            Console.WriteLine(string.Format("年月期格式：{0:Y}", strDate));

方法二：

             int money = 1298;
             Console.WriteLine(money.ToString("C"));
             DateTime strDate = DateTime.Now;
             Console.WriteLine(strDate.ToString("f"));
