Question

I am currently developing a windows form application and I have a arraylist notificationList that contains notificationForms.

How do I use a for loop to loop through every single form in the arrayList to check if the forms are disposed through the isDisposed property?

int formDisposed = 0;  

for (int i = 0; i < notificationList.Count; i++)
{
    if(notificationList.?????.IsDisposed == true)
    {
      formDisposed ++;
    }
}

Thanks!

Answer 1

Usually by using

if(notificationList[i].IsDisposed)

if for some reason you don’t have this option: add the following line to your .cs file

using System.Data;

and Syste.Data and Syste.Data.DataSetExtensions so you will able to access xxx.ElementAt(i) method.

You can also use foreach:

int formDisposed = 0;  

foreach (Form f in notificationList)
{
    if(f.IsDisposed)
      formDisposed ++;
}
