需要检查输入是否为小数

Question

所以我在C＃中为类编写控制台应用程序，我需要弄清楚如何检查输入是否为小数。它将遵循我到目前为止编写的代码：

Console.Write("Enter the annual amount of money saved: ");

decimal moneySaved = Convert.ToDecimal(Console.ReadLine());

在检查输入后，我希望它输出类似＆＃34;您没有输入数字，请再试一次。＆＃34;

提前致谢！

Answer 1

 Console.Write("Enter the annual amount of money saved: ");
 string moneySaved = Console.ReadLine();
 decimal number;
 if (Decimal.TryParse(moneySaved, out number))
 {
   Console.Write("You entered a decimal number");
 }
 else
 {
  Console.Write("You didn't enter a number, please try again.");
 }
