C# Int64.Equals用法及代碼示例

Int64.Equals()方法用於獲取一個值，該值顯示當前實例是否等於指定的對象或Int64。此方法的重載列表中有2種方法，如下所示：

Equals(Int64)
Equals(Object)

Int64.Equals(Int64)

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Int64值。

用法： public bool Equals (long obj);

Here, it takes a Int64 value to compare to this 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Int64.Equals(Int64)方法的使用：

範例1：

// C# program to demonstrate the 
// Int64.Equals(Int64) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        long value1 = 45643242; 
  
        // Declaring and initializing value2 
        long value2 = 2564233; 
  
        // using Equals(Int64) 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：

45643242 is not equal to 2564233

範例2：

// C# program to demonstrate the 
// Int64.Equals(Int64) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
  
        // calling get() method 
        get(44355, 578); 
        get(423445, 423445); 
        get(12560, 28960); 
        get(778, 798); 
    } 
  
    // defining get() method 
    public static void get(long value1, 
                           long value2) 
    { 
  
        // using Equals(Int64) 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：

44355 is not equal to 578
423445 is equal to 423445
12560 is not equal to 28960
778 is not equal to 798

Int64.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 this instance.

返回值：如果obj是Int64的實例，並且此實例的值等於False，則此方法返回true。

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 
// Int64.Equals(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // Declaring and initializing value1 
        long value1 = 1879650; 
  
        // Declaring and initializing value2 
        object value2 = 1/45; 
  
        // 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：

1879650 is not equal to 0

範例2：

// C# program to demonstrate the 
// Int64.Equals(Object) Method 
using System; 
using System.Globalization; 
  
class GFG { 
  
    // Main Method 
    public static void Main() 
    { 
        // calling get() method 
        get(54547, 54585); 
        get(555, 489); 
        get(10450, 10450); 
        get(745, 745); 
    } 
  
    // defining get() method 
    public static void get(long 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：

54547 is not equal to 54585
555 is not equal to 489
10450 is not equal to 10450
745 is equal to 745
