📜  C#|检查一个数组对象是否等于另一个数组对象

数组是一组由通用名称引用的相似类型的变量。每个数据项都称为数组的元素。 Array类从object类继承的Equals(Object)方法用于检查一个数组是否等于另一个数组。

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 a Array is
// equal to other Array or not
using System;
  
namespace geeksforgeeks {
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // Two-dimensional array
        int[, ] intarray = new int[, ] { { 1, 2 },
                                         { 3, 4 },
                                         { 5, 6 },
                                         { 7, 8 } };
  
        // check if intarray is
        // equal to itself or not
        Console.WriteLine(intarray.Equals(intarray));
    }
}
}
输出:
True

范例2:

// C# code to check if an Array is
// equal to other Array or not
using System;
  
namespace geeksforgeeks {
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
      
        // Creating and intializing new the String
        String[] arr1 = new String[4] { "Sun", "Mon", "Tue", "Thu" };
          
          
        // taking anotther array
        String[] arr2 = new String[4] { "Sun", "Mon", "Tue", "Thu" };
          
  
        // check if arr1 is
        // equal to arr2 or not
        Console.WriteLine(arr1.Equals(arr2));
          
        // assigning arr1 reference to arr3
        String[] arr3 = new String[4];
        arr3 = arr1;
          
        // check if arr2 is
        // equal to arr3 or not
        Console.WriteLine(arr2.Equals(arr3));
          
        // check if arr1 is
        // equal to arr3 or not
        // it will return true as both 
        // array object refer to same
        Console.WriteLine(arr1.Equals(arr3));
          
    }
}
}
输出:
False
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。
