In this article, I will explain, How to use ForEach Method with Collection in C#.It is help to reduces number of lines code compare with normal for each method and simple.


public void ForEach(Action<t> action)

Action<t> is delegate or function to perform on each element of the List.

To get in more detail how it works check check the following code.Below is Employee class which has property related to employee of the company.

public class Employee
        public string Name { get; set; }
        public int Salary { get; set; }
        public string Address { get; set; }
        public int Id { get; set; }

and now in following line of code I am initializing list of employees

class Program
        static void Main(string[] args)
          List<employee> emplst = new List<employee> {
          new Employee() { Name="pranay", Address = "Ahmedabad", Id=1, Salary=1234},
          new Employee() { Name="Hemang", Address = "Ahmedabad", Id=2, Salary=2348},
          new Employee() { Name="kurnal", Address = "Himmatnagar", Id=3, Salary=8999},
          new Employee() { Name="Hanika", Address = "Ahmedabad", Id=4, Salary=7888}

Now I want to increase salary of each employee by 10%, so with the the help of new ForEach construct I can easily achieve it by using following line of code.

emplst.ForEach(new Program().incSalary);
  private void incSalary(Employee emp)
     emp.Salary += (emp.Salary * 10)/100;

As you can see in above code I have written new Program().incSalary as action, in the incsalary method as you see I increase the salary of each employee 10%.
This thing can easily also done by making use of the foreach loop available but if you see the the ForEach in reflector it does the same thing.

ForEach method make code more simple and easy to understand.Hopes help and thank you reading.
