    Max aggregate operator is used to find the largest item from a collection.


    Exapmle:-
    In the below example we created a complex type collection for an Employee. This Employee collection contains EmpId, EmpName and Age. We need to find a maximum employee age.


    Code:-

    IList<Employee> empList = new List<Employee>() { 
            new Employee() { EmpID = Guid.NewGuid().ToString(), EmpName = "John", Age = 33} ,
            new Employee() { EmpID = Guid.NewGuid().ToString(), EmpName = "Mohan",  Age = 41 } ,
            new Employee() { EmpID = Guid.NewGuid().ToString(), EmpName = "Bin",  Age = 28 } ,
            new Employee() { EmpID = Guid.NewGuid().ToString(), EmpName = "Ram" , Age = 20} ,
            new Employee() { EmpID = Guid.NewGuid().ToString(),  EmpName = "Rohan" , Age = 35 } 
        };
    var oldestEmp = empList.Max(s => s.Age);
    Console.WriteLine("Oldest Employee Age: {0}", oldestEmp);
    

     


    Output:-

     

    Max aggregate operator is not supported in C# Query syntax but it is supported in VB.Net.
    Query syntax in vb.net:-
    code:-

    Dim empList = New List(Of Employee) From {
     New Employee() With {.EmpID = Guid.NewGuid().ToString(), .EmpName = "John", .Age = 13},
     New Employee() With {.EmpID = Guid.NewGuid().ToString(), .EmpName = "Mohan", .Age = 21},
     New Employee() With {.EmpID = Guid.NewGuid().ToString(), .EmpName = "Bin", .Age = 18},
     New Employee() With {.EmpID = Guid.NewGuid().ToString(), .EmpName = "Ram", .Age = 20},
     New Employee() With {.EmpID = Guid.NewGuid().ToString(), .EmpName = "Rohan", .Age = 15}
    }
    Dim empMaxAge = Aggregate emp In empList Into Max(emp.Age)
    Console.WriteLine("Maximum Age of Employee: {0}", empMaxAge);
    

     

    Output:-
