Hi, There is no problem for printing your ArrayyList values by following. ArrayList arr = new ArrayList(); arr.Add("Manoj"); arr.Add(4); arr.Add(4.5); for (int i = 0; i < arr.Count; i++) lblResult.Text += arr[i];

you can use ToString for primitive types like int ,double,string,... but in some cases ToString does not return the data we expect (like classes we define by our self) so in those cases you can override the ToString() method.

foreach(object obj in arr)
Console.WriteLine(obj.ToString());

hope the post would be useful

In addition to the ToString() method suggested above, you can also use GetType() on any object which returns an object of type Type. This object has all the information you could ever need on what types are inside your arraylist.

I think you should use an object then add it to your arraylist. such as You can create an object: myObject obj =new myObject(); obj.Title="Manoj"; obj.Age=4; obj.Weight=4.5; //Add to arraylist ArrayList arr = new ArrayList(); arr.Add(obj); //Get from arraylist for(int i = 0; i < arr.Count; i++) { myObject obj = arr[i] as myObject; Console.Write(obj.Title); .... } Hope that help you vtkiet05
