    Sub Main()
        Dim empList = New List(Of Employee) From

            New Employee() With {.id = 102, .name = "Arun", .age = 22, .salary = 5500},
            New Employee() With {.id = 103, .name = "Aman", .age = 23, .salary = 6000},
            New Employee() With {.id = 104, .name = "Amar", .age = 21, .salary = 6700},
            New Employee() With {.id = 105, .name = "Akki", .age = 26, .salary = 7500},
            New Employee() With {.id = 105, .name = "Anuj", .age = 23, .salary = 8700}
        }

        Dim Result = empList.TakeWhile(Function(e) e.salary < 7000)


        Console.WriteLine("Employees: ")
        For Each emp In Result
            Console.WriteLine(emp.id & " " & emp.name & " " & emp.age & " " & emp.salary)
        Next
    End Sub
End Module

Output

Employees:
101 Amit 21 5000
102 Arun 22 5500
103 Aman 23 6000
104 Amar 21 6700

Explanation

In the above program, we created a module Module1 that contains Employee class and a Main() function. The Employee class contains the data member id, name, age, and salary.

The Main() function is the entry point for the program. In the Main() function, we created a list of employees and then get the employee records in the collection till the specified condition is true using TakeWhile() LINQ extension method and after that, we printed the result on the console screen.
