需要檢查輸入是否是小數或不是

Question

因此，我在C＃中爲類編寫控制檯應用程序，我需要弄清楚如何檢查輸入是否爲小數。它檢查輸入我希望它輸出像後

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

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

：它會按照這個代碼，我到目前爲止已經寫了「你沒有輸入號碼，請重試。」

提前致謝！

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."); 
}
