Gets the number of items in the collection.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
This property enables you to determine the number of selected items in the ListView. You can then use this value when you are looping through the values of the collection and need to provide a number of iterations to perform the loop. If the MultiSelect property of the ListView is set to false, this property returns a value of either 0 or 1 depending on whether an item is selected.
