从Object类继承的Equals(Object)方法用于检查指定的SortedList对象是否等于另一个SortedList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# program to if a SortedList
// is equal to another SortedList
using System;
using System.Collections;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Creating a sorted list of key/value pairs
SortedList fslist = new SortedList();
// Adding pairs to fslist
fslist.Add("Maths ", 98);
fslist.Add("English ", 99);
fslist.Add("Physics ", 97);
fslist.Add("Chemistry", 96);
fslist.Add("CSE ", 100);
// Checking whether fslist is
// equal to itself or not
Console.WriteLine(fslist.Equals(fslist));
}
}
输出:
True
范例2:
// C# program to if a SortedList
// is equal to another SortedList
using System;
using System.Collections;
class Geeks {
// Main Method
public static void Main(String[] args)
{
// Creating a sorted list of key/value pairs
SortedList fslist = new SortedList();
// Adding pairs to fslist
fslist.Add("Maths ", 98);
fslist.Add("English ", 99);
fslist.Add("Physics ", 97);
fslist.Add("Chemistry", 96);
fslist.Add("CSE ", 100);
// Creating an SortedList
SortedList fslist2 = new SortedList();
// Adding elements to SortedList
fslist2.Add("1", "one");
fslist2.Add("2", "two");
fslist2.Add("3", "three");
fslist2.Add("4", "four");
fslist2.Add("5", "five");
// Checking whether fslist is
// equal to fslist2 or not
Console.WriteLine(fslist.Equals(fslist2));
// Creating a sorted list of key/value pairs
SortedList fslist3 = new SortedList();
// Assigning fslist2 to fslist3
fslist3 = fslist2;
// Checking whether fslist3 is
// equal to fslist2 or not
Console.WriteLine(fslist3.Equals(fslist2));
}
}
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。
