Remarks

The System.Windows.Forms.ComboBox.ObjectCollection class encapsulates the items in the ComboBox. The object collection of a combo box can be used to manage many types of objects, including strings, images, and custom business objects.

You can add items to the collection in several ways. The Add method adds one object to the collection. To add a number of objects to the collection, it is best to create an array of items and assign with the AddRange method. To insert an object at a specific location within the collection, you can use the Insert method. To remove items at a known index in the collection you can use either the Remove method or the RemoveAt method. The Clear method removes all the items from the collection.

In addition to methods and properties for adding and removing items, the System.Windows.Forms.ComboBox.ObjectCollection also provides methods to find items within the collection. The Contains method enables you to determine if an object is a member of the collection. Once you know that the item is located within the collection, you can use the IndexOf method to determine where the item is located within the collection.
