📜  检查两个SortedDictionary对象在C#中是否相等

从Object类继承的Equals(Object)方法用于检查指定的SortedDictionary对象是否等于另一个SortedDictionary对象。

句法:

public virtual bool Equals (object obj);

此处, obj是要与当前对象进行比较的对象。

返回值:如果指定对象等于当前对象,则此方法返回true ,否则返回false

下面的程序说明了上面讨论的方法的使用:

范例1:

// C# code to check if the two
// SortedDictionary are equal or not
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a SortedDictionary named myDict
        SortedDictionary myDict = 
           new SortedDictionary();
  
        // Adding key/value pairs in myDict
        myDict.Add("Australia", "Canberra");
        myDict.Add("Belgium", "Brussels");
        myDict.Add("Netherlands", "Amsterdam");
        myDict.Add("China", "Beijing");
        myDict.Add("Russia", "Moscow");
        myDict.Add("India", "New Delhi");
  
        // Checking whether myDict is
        // equal to itself or not
        Console.WriteLine(myDict.Equals(myDict));
    }
}
输出:
True

范例2:

// C# code to check if the two
// SortedDictionary are equal or not
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a SortedDictionary named myDict
        SortedDictionary myDict1 = 
            new SortedDictionary();
  
        // Adding key/value pairs in myDict
        myDict1.Add("I", "first");
        myDict1.Add("II", "second");
        myDict1.Add("III", "third");
        myDict1.Add("IV", "fourth");
        myDict1.Add("V", "fifth");
  
        // Creating a SortedDictionary named myDict2
        SortedDictionary myDict2 = 
             new SortedDictionary();
  
        myDict2.Add("1st", "C");
        myDict2.Add("2nd", "C++");
        myDict2.Add("3rd", "Java");
        myDict2.Add("4th", "C#");
        myDict2.Add("5th", "HTML");
        myDict2.Add("6th", "PHP");
  
        // Checking whether myDict1 is
        // equal to myDict2 or not
        Console.WriteLine(myDict1.Equals(myDict2));
  
        // Creating a new SortedDictionary
        SortedDictionary myDict3 = 
            new SortedDictionary();
  
        // Assigning myDict2 to myDict3
        myDict3 = myDict2;
  
        // Checking whether myDict3 is
        // equal to myDict2 or not
        Console.WriteLine(myDict3.Equals(myDict2));
    }
}
输出:
False
True

注意:如果当前实例是引用类型,则Equals(Object)方法将检查引用是否相等。
