retrieving specific items from an ArrayList

Question

I am really struggling with how to obtain the index of an object in an array list via a specific property value of said object. If anyone could provide me with a method for how to do this it would be VERY much appreciated. I have an array list that contains several task objects. These objects can have a status of active inactive held alerting etc. If I have 3 task objects in my arrayList like the ones below... index0 = task.alerting index1 = task.active index2 = task.held How can I cycle through the array list looking for the one with a state of alerting??? Please help. Thank you. Bob

Cycle through it like you would do with a regular array from index 0 to ArrayList.Count-1. For each object in the list check its task state and if it is task.alerting return the index of that object. I believe I posted this in another thread... If you mean that task objects are enumerations where three possible values are Task.Alerting Task.Active and Task.Held this method should do it. public static int getIndexOfAlertingTask(ArrayList arrayList) { for (int i=0; i indexer and a for loop and check whether or not each object's state is alerting.
