C# Queryable SequenceEqual() Method

To check whether two sequences are equal or not, use the SequenceEqual() method.

Firstly, set the sequences.

Employee emp1 = new Employee { EmployeeRank = 4, EmpName = "Amit", EmpMarks = 90 };
Employee emp2 = new Employee { EmployeeRank = 5, EmpName = "Raman", EmpMarks = 95 };
List<Employee> employee1 = new List<Employee> { emp1, emp2 };
List<Employee> employee2 = new List<Employee> { emp1, emp2 };

Now, find whether the sequences are equal or not.

employee1.AsQueryable().SequenceEqual(employee2);

Here is the example that shows the result.

Exmaple

using System;
using System.Linq;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      Employee emp1 = new Employee { EmployeeRank = 4, EmpName = "Amit", EmpMarks = 90 };
      Employee emp2 = new Employee { EmployeeRank = 5, EmpName = "Raman", EmpMarks = 95 };
      List<Employee> employee1 = new List<Employee> { emp1, emp2 };
      List<Employee> employee2 = new List<Employee> { emp1, emp2 };
      bool res = employee1.AsQueryable().SequenceEqual(employee2);
      Console.WriteLine("Lists are equal? = "+res);
   }
}

public class Employee {
   public int EmployeeRank { get; set; }
   public string EmpName { get; set; }
   public int EmpMarks { get; set; }
}

Output

Lists are equal? = True
