C＃中的Decimal.Compare()方法

此方法用于比较两个指定的十进制值。

Syntax: public static int Compare (decimal a1, decimal a2);

Parameters:
a1:This parameter specifies the first value to compare.
a2:This parameter specifies the second value to compare.

Return Value: It returns a signed number indicating the relative values of a1 & a2.

• If the value is less than zero, it means a1 is less than a2.
• If the value is greater than zero, it means a1 is greater than a2.
• If the value is zero, it means a1 is equal to a2.

下面的程序说明了Decimal.Compare(Decimal，Decimal)方法的用法

示例1：当a1大于a2时。

// C# program to demonstrate the
// Decimal.Compare(Decimal, 
// Decimal) Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring the decimal variables
        Decimal a1 = 4;
        Decimal a2 = 3;
  
        // comparing the two Decimal value
        // using Compare() method;
        Decimal value = Decimal.Compare(a1, a2);
  
        // Display the compare value
        Console.WriteLine("The compare value is : {0}",
                                                value);
    }
}

输出：

The compare value is : 1

示例2：当a1小于a2时。

// C# program to demonstrate the
// Decimal.Compare(Decimal,
// Decimal) Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring the decimal variables
        Decimal a1 = 1;
        Decimal a2 = 9;
  
        // comparing the two Decimal value
        // using Compare() method;
        Decimal value = Decimal.Compare(a1, a2);
  
        // Display the compare value
        Console.WriteLine("The compare value is : {0}",
                                                value);
    }
}

输出：

The compare value is : -1

示例3：当a1等于a2时。

// C# program to demonstrate the
// Decimal.Compare(Decimal,
// Decimal) Method
using System;
using System.Globalization;
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Declaring the decimal variables
        Decimal a1 = 5;
        Decimal a2 = 5;
  
        // comparing the two Decimal value
        // using Compare() method;
        Decimal value = Decimal.Compare(a1, a2);
  
        // Display the compare value
        Console.WriteLine("The compare value is : {0}",
                                                value);
    }
}

输出：

The compare value is : 0
