C＃中的Decimal.ToOACurrency()方法

Decimal.ToOACurrency(Decimal)方法用于将指定的Decimal值转换为等效的OLE自动化货币值，该值包含在64位带符号整数中。

Syntax: public static long ToOACurrency (decimal value);
Here, it takes the decimal number to convert.

Return Value: This method returns a 64-bit signed integer that contains the OLE Automation equivalent of value.

下面的程序说明了Decimal.ToOACurrency()方法的用法

范例1：

// C# program to demonstrate the
// Decimal.ToOACurrency() Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        Decimal curr = 40;
  
        // A 64-bit signed integer that contains
        // the OLE Automation equivalent of value.
        long value = Decimal.ToOACurrency(curr);
  
        // Display the HashCode
        Console.WriteLine("Equivalent long value is {0}", value);
    }
}

输出：

Equivalent long value is 400000

范例2：

// C# program to demonstrate the
// Decimal.ToOACurrency() Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
        // calling get() method
        Console.WriteLine("Equivalent long value are respectivily");
        get(20);
        get(30);
        get(40);
        get(4294967295);
    }
  
    // defining get() method
    public static void get(decimal curr)
    {
  
        // getting Equivalent decimal value
        // using ToOACurrency() method
        long value = Decimal.ToOACurrency(curr);
  
        // Display the HashCode
        Console.WriteLine("{0}", value);
    }
}

输出：

Equivalent long value are respectivily
200000
300000
400000
42949672950000
