C# Decimal.ToInt16()用法及代碼示例

此方法用於將指定的Decimal的值轉換為等效的16位帶符號整數。用戶還可以使用Explicit賦值運算符將Decimal值轉換為16位整數。

用法： public static short ToInt16 (decimal value);

Here, the value is the decimal number which is to be converted.

返回值：它返回一個等效於指定值的16位帶符號整數。

異常：如果指定的值小於MinValue或大於MaxValue，則此方法將給出OverflowException。

以下示例程序旨在說明上述方法的用法：

示例1:

// C# program to demonstrate the 
// Decimal.ToInt16(Decimal) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Taking decimal variables 
            Decimal dec1 = 21564.236M; 
            Decimal dec2 = 32767.256m; 
   
            // using Decimal.ToInt16(Decimal) Method 
            // Here short means Int16 
            short val1 = Decimal.ToInt16(dec1); 
               
            // using Decimal.ToInt16(Decimal) Method 
            // Here short means Int16 
            short val2 = Decimal.ToInt16(dec2); 
               
   
            // Printing the Int16 value 
            Console.WriteLine("The Int16 value "
                              + "is : {0}", val1); 
                                 
            // Printing the Int16 value 
            Console.WriteLine("The Int16 value "
                              + "is : {0}", val2); 
                           
        } 
   
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

The Int16 value is : 21564
The Int16 value is : 32767

示例2:對於OverflowException

// C# program to demonstrate the 
// Decimal.ToInt16(Decimal) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Taking decimal variable 
            // Taking the maximum value  
            // of Decimal 
            Decimal dec1 = Decimal.MaxValue; 
   
            // using Decimal.ToInt16(Decimal) Method 
            // Here short means Int16 
            // It will give error as Decimal.MaxValue 
            // value is out of range from Int16 
            short val1 = Decimal.ToInt16(dec1); 
               
   
            // Printing the Int16 value 
            Console.WriteLine("The Int16 value "
                              + "is : {0}", val1); 
        } 
   
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

Exception Thrown: System.OverflowException
