C# UInt64.CompareTo()用法及代码示例


UInt64.CompareTo方法用于将当前实例与指定对象或另一个UInt64实例进行比较。它返回一个整数，该整数显示当前实例的值是小于，等于还是大于指定对象或另一个UInt64实例的值。此方法的重载列表中有2种方法，如下所示：

    • CompareTo(UInt64)方法
    • CompareTo(Object)方法

UInt64.CompareTo(UInt64)方法

此方法用于将当前实例与指定的64位无符号长整数进行比较，并返回一个整数，该整数显示当前实例的值是否小于，等于或大于指定的64位无符号值。长整数。


用法:

public int CompareTo (ulong value);

在这里，它需要一个无符号的long值进行比较。

返回值：它返回一个32位带符号的数字，指示当前实例和value参数的相对值，如下所示：

  • 小于零：如果当前实例
  • 零：如果当前实例=值
  • 大于零：如果当前实例>值

以下示例程序旨在说明UInt64.CompareTo(UInt64)方法的用法：

示例1: 

// C# program to demonstrate the 
// UInt64.CompareTo(UInt64) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // Declaring and initializing value1 
        ulong value1 = 312312131231; 
  
        // Declaring and initializing value2 
        ulong value2 = 523564123; 
  
        // using CompareTo() method 
        int status = value1.CompareTo(value2); 
  
        // checking the status 
        if (status > 0) 
            Console.WriteLine("{0} is greater than {1}", 
                                        value1, value2); 
        else if (status < 0) 
            Console.WriteLine("{0} is less than {1}", 
                                     value1, value2); 
        else
            Console.WriteLine("{0} is equal to {1}", 
                                    value1, value2); 
    } 
}
输出： 
312312131231 is greater than 523564123

示例2: 

// C# program to demonstrate the 
// UInt64.CompareTo(UInt64) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(34432425, 708343); 
        get(3780, 8920); 
        get(8543453910, 85345340920); 
        get(7006789, 7006789); 
    } 
  
    // defining get() method 
    public static void get(ulong value1, 
                           ulong value2) 
    { 
  
        // using CompareTo() method 
        int status = value1.CompareTo(value2); 
  
        // checking the status 
        if (status > 0) 
            Console.WriteLine("{0} is greater than {1}", 
                                        value1, value2); 
        else if (status < 0) 
            Console.WriteLine("{0} is less than {1}", 
                                     value1, value2); 
        else
            Console.WriteLine("{0} is equal to {1}", 
                                    value1, value2); 
    } 
}
输出： 
34432425 is greater than 708343
3780 is less than 8920
8543453910 is less than 85345340920
7006789 is equal to 7006789

UInt64.CompareTo(Object)方法

此方法用于将当前实例与指定对象进行比较，并返回一个整数，该整数指示当前实例的值是小于，等于还是大于对象的值。

用法: 


public int CompareTo (object value);

在这里，它需要对象与该实例进行比较，或者为null。

返回值：它返回一个32位带符号的数字，指示当前实例和value参数的相对值，如下所示：

  • 小于零：如果当前实例
  • 零：如果当前实例=值
  • 大于零：如果当前实例>值

异常：如果value不是UInt64，则抛出ArgumentException。

以下示例程序旨在说明UInt64.CompareTo(Object)方法的用法

示例1:

// C# program to demonstrate the 
// UInt64.CompareTo(Object) Method 
using System; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            ulong value1 = 2324313420; 
  
            // Declaring and initializing value2 
            object value2 = (ulong)687.876; 
  
            // using CompareTo() method 
            int status = value1.CompareTo(value2); 
  
            // checking the status 
            if (status > 0) 
                Console.WriteLine("{0} is greater than {1}", 
                                           value1, value2); 
  
            else if (status < 0) 
                Console.WriteLine("{0} is less than {1}", 
                                         value1, value2); 
            else
                Console.WriteLine("{0} is equal to {1}", 
                                        value1, value2); 
        } 
  
        catch (ArgumentException e) 
        { 
            Console.WriteLine("value2 must be null"+ 
                       " or an instance of UInt32"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出： 
2324313420 is greater than 687

示例2:对于ArgumentException

// C# program to demonstrate the 
// UInt64.CompareTo(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        try { 
  
            // Declaring and initializing value1 
            ulong value1 = 104646549854; 
  
            // Declaring and initializing value2 
            object value2 = 1 / 6; 
  
            // using CompareTo() method 
            int status = value1.CompareTo(value2); 
  
            // checking the status 
            if (status > 0) 
                Console.WriteLine("{0} is greater than {1}", 
                                            value1, value2); 
  
            else if (status < 0) 
                Console.WriteLine("{0} is less than {1}", 
                                         value1, value2); 
            else
                Console.WriteLine("{0} is equal to {1}", 
                                        value1, value2); 
        } 
  
        catch (ArgumentException e) 
        { 
            Console.WriteLine("value2 must be null"+ 
                       " or an instance of UInt64"); 
            Console.Write("Exception Thrown: "); 
            Console.Write("{0}", e.GetType(), e.Message); 
        } 
    } 
}
输出： 
value2 must be null or an instance of UInt64
Exception Thrown: System.ArgumentException
