C# UInt64.CompareTo()用法及代碼示例


UInt64.CompareTo方法用於將當前實例與指定對象或另一個UInt64實例進行比較。它返回一個整數，該整數顯示當前實例的值是小於，等於還是大於指定對象或另一個UInt64實例的值。此方法的重載列表中有2種方法，如下所示：

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

UInt64.CompareTo(UInt64)方法

此方法用於將當前實例與指定的64位無符號長整數進行比較，並返回一個整數，該整數顯示當前實例的值是否小於，等於或大於指定的64位無符號值。長整數。


用法:

public int CompareTo (ulong value);

在這裏，它需要一個無符號的long值進行比較。

返回值：它返回一個32位帶符號的數字，指示當前實例和value參數的相對值，如下所示：

  • 小於零：如果當前實例
  • 零：如果當前實例=值
  • 大於零：如果當前實例>值

以下示例程序旨在說明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); 
    } 
}
輸出： 
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); 
    } 
}
輸出： 
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

此方法用於將當前實例與指定對象進行比較，並返回一個整數，該整數指示當前實例的值是小於，等於還是大於對象的值。

用法: 


public int CompareTo (object value);

在這裏，它需要對象與該實例進行比較，或者為null。

返回值：它返回一個32位帶符號的數字，指示當前實例和value參數的相對值，如下所示：

  • 小於零：如果當前實例
  • 零：如果當前實例=值
  • 大於零：如果當前實例>值

異常：如果value不是UInt64，則拋出ArgumentException。

以下示例程序旨在說明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); 
        } 
    } 
}
輸出： 
2324313420 is greater than 687

示例2:對於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); 
        } 
    } 
}
輸出： 
value2 must be null or an instance of UInt64
Exception Thrown: System.ArgumentException
