How to iterate through System.Generic.List<T>

  Hi,

  I've gone through that foreach, but how to declare any Action<T>, can you give me some examples.

  You can iterate easily with Action<T> delegate

  List<string> list = new List<string>();

  foreach (string item in list)

  {

  Console.WriteLine(item);

  }

  If you need delegate (but this is more code):

  data.ForEach(MyAction);

  ...

  void MyAction(string item)

  {

  Console.WriteLine(item);

  }

  Thanks Galich. Your first suggestion helped me out.

  But In your other suggestion:

  data.ForEach(MyAction);

  ...

  void MyAction(string item)

  {

  Console.WriteLine(item);

  }

  "MyAction" method is having one argument parameter, but in this line of code "data.ForEach(MyAction);", you are not passing-on any value, I'm confused, plz. help me with it.

  In second case, list will iterate itself and call your method passing values to it. It's not often used, more often used foreach() statement. If you want know more - read about delegates in MSDN.
