C# Decimal.Multiply()用法及代碼示例

此方法用於將兩個指定的十進製值相乘。

用法： public static decimal Multiply (decimal a1, decimal a2);

參數：
a1：此參數指定被乘數。
a2：此參數指定乘數。

返回值：a1和a2相乘的結果。

異常：如果返回值小於MinValue或大於MaxValue，則此方法將給出OverflowException。

以下示例程序旨在說明Decimal.Multiply(Decimal，Decimal)方法的用法

示例1:

// C# program to demonstrate the 
// Decimal.Multiply(Decimal, 
// Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring the decimal variables 
            Decimal a1 = 4.02m; 
            Decimal a2 = 2.01m; 
  
            // multiplying the two Decimal value 
            // using Multiplying() method; 
            Decimal value = Decimal.Multiply(a1, a2); 
  
            // Display the prduct 
            Console.WriteLine("Result of multiplication : {0}", 
                                                        value); 
        } 
  
        catch (OverflowException e) { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

Result of multiplication : 8.0802

// C# program to demonstrate the 
// Decimal.Multiply(Decimal,  
// Decimal) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring the decimal variables 
            Decimal a1 = 4.02m; 
            Decimal a2 = Decimal.MaxValue; 
  
            // multiplying the two Decimal value 
            // using Multiply() method; 
            Decimal value = Decimal.Multiply(a1, a2); 
  
            // Display the product 
            Console.WriteLine("Result of multiplication : {0}", 
                                                        value); 
        } 
  
        catch (OverflowException e)  
        { 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}

輸出：

Exception Thrown: System.OverflowException
