C# UInt64.Equals用法及代碼示例

UInt64.Equals方法用於獲取一個值，該值指示當前實例是否等於指定的對象或64位無符號長整數。此方法的重載列表中有2種方法，如下所示：

    • Equals(UInt64)方法
    • Equals(Object)方法

UInt64.Equals(UInt64) Method

此方法用於返回一個值，該值指示當前實例是否等於指定的64位無符號長整數值。


用法： public bool Equals (ulong obj);

Here, it takes a 64-bit unsigned long integer value to compare to the current instance.

返回值：如果obj與該實例具有相同的值，則此方法返回true，否則返回false。

以下示例程序旨在說明UInt64.Equals(UInt64)方法的用法：

範例1：

// C# program to demonstrate the 
// UInt64.Equals(UInt64) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        ulong value1 = 5232642; 
  
        // Declaring and initializing value2 
        ulong value2 = 2317648; 
  
        // using Equals(UInt64) method 
        bool status = value1.Equals(value2); 
  
        // checking the status 
        if (status) 
            Console.WriteLine("{0} is equal to {1}", 
                                    value1, value2); 
        else
            Console.WriteLine("{0} is not equal to {1}", 
                                        value1, value2); 
    } 
}
輸出： 
5232642 is not equal to 2317648

範例2：

// C# program to demonstrate the 
// UInt64.Equals(UInt64) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // calling get() method 
        get(9213128, 2131978); 
        get(656455, 656455); 
        get(10120, 10120); 
        get(UInt64.MaxValue, UInt64.MinValue); 
    } 
  
    // defining get() method 
    public static void get(ulong value1, 
                           ulong value2) 
    { 
  
        // using Equals(UInt64) method 
        bool status = value1.Equals(value2); 
  
        // checking the status 
        if (status) 
            Console.WriteLine("{0} is equal to {1}", 
                                    value1, value2); 
        else
            Console.WriteLine("{0} is not equal to {1}", 
                                        value1, value2); 
    } 
}
輸出： 
9213128 is not equal to 2131978
656455 is equal to 656455
10120 is equal to 10120
18446744073709551615 is not equal to 0

UInt64.Equals(Object) Method

此方法用於返回一個值，該值指示當前實例是否等於指定的對象。

用法： public override bool Equals (object obj);

Here, it takes an object to compare with the current instance.

返回值：如果obj是UInt64的一個實例，並且等於該實例的值，則此方法返回true，否則返回false。


以下示例程序旨在說明上述方法的用法：

範例1：

// C# program to demonstrate the 
// UInt64.Equals(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        ulong value1 = 13421227; 
  
        // Declaring and initializing value2 
        object value2 = 1 / 417; 
  
        // using Equals(object) method 
        bool status = value1.Equals(value2); 
  
        // checking the status 
        if (status) 
            Console.WriteLine("{0} is equal to {1}", 
                                    value1, value2); 
        else
            Console.WriteLine("{0} is not equal to {1}", 
                                        value1, value2); 
    } 
}
輸出： 
13421227 is not equal to 0

範例2：

// C# program to demonstrate the 
// UInt64.Equals(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(1231264, 7234455); 
        get(1423412, (ulong)14432314); 
        get(7742344, (ulong)7742344); 
        get(5443, 7346); 
    } 
  
    // defining get() method 
    public static void get(ulong value1, 
                           object value2) 
    { 
  
        // using Equals(object) method 
        bool status = value1.Equals(value2); 
  
        // checking the status 
        if (status) 
            Console.WriteLine("{0} is equal to {1}", 
                                    value1, value2); 
        else
            Console.WriteLine("{0} is not equal to {1}", 
                                        value1, value2); 
    } 
}
輸出： 
1231264 is not equal to 7234455
1423412 is not equal to 14432314
7742344 is equal to 7742344
5443 is not equal to 7346
