C# |检查两个链表对象是否相等T3】
原文:https://www . geeksforgeeks . org/c-sharp-check-if-twin-linked list-objects-equal/
从 Object 类继承的 Equals(Object)方法用于检查指定的链表T3】对象是否等于另一个链表< T >对象。
语法:
public virtual bool Equals (object obj);
这里， 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，则该方法返回真，否则返回假。
以下程序说明了上述方法的使用:
例 1:
// C# program to if a LinkedList object
// is equal to another LinkedList object
using System;
using System.Collections.Generic;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Creating a LinkedList of Strings
LinkedList<String> myList1 = new LinkedList<String>();
// Adding nodes in LinkedList
myList1.AddLast("Geeks");
myList1.AddLast("for");
myList1.AddLast("Data Structures");
myList1.AddLast("Noida");
// Checking whether myList1 is
// equal to itself or not
Console.WriteLine(myList1.Equals(myList1));
}
}
Output:
True
例 2:
// C# program to if a LinkedList object
// is equal to another LinkedList object
using System;
using System.Collections.Generic;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Creating a LinkedList of Strings
LinkedList<String> myList1 = new LinkedList<String>();
// Adding nodes in LinkedList
myList1.AddLast("C");
myList1.AddLast("C++");
myList1.AddLast("Java");
myList1.AddLast("C#");
// Creating a LinkedList of Integers
LinkedList<int> myList2 = new LinkedList<int>();
// Adding nodes in LinkedList
myList2.AddLast(2);
myList2.AddLast(4);
myList2.AddLast(6);
myList2.AddLast(8);
// Checking whether myList1 is
// equal to myList2 or not
Console.WriteLine(myList1.Equals(myList2));
// Creating a LinkedList of Integers
LinkedList<int> myList3 = new LinkedList<int>();
// Assigning myList2 to myList3
myList3 = myList2;
// Checking whether myList3 is
// equal to myList2 or not
Console.WriteLine(myList3.Equals(myList2));
}
}
Output:
False
True
注意:如果当前实例是引用类型， Equals(Object)方法检查引用是否相等。
