需要检查输入是否是小数或不是

Question

因此，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。它检查输入我希望它输出像后

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

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

：它会按照这个代码，我到目前为止已经写了“你没有输入号码，请重试。”

提前致谢！

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."); 
}
