You may experience one or more of the following problems:
- Problem 1
You call the TrimToSize method, and then you call the Dequeue method. If you call the Enqueue method later, you may experience a System.IndexOutOfRangeException error. When this problem occurs, you receive an error message that is similar to the following: Index was outside the bounds of the array
- Problem 2
When you call the Clone method, the Count property of the resulting clone reports correctly that it contains the same number of queued items as the original. However, when you call the Dequeue method to remove items from the Queue object, you may experience a System.NullReferenceException error. When this problem occurs, you receive an error message that is similar to the following: Object reference not set to an instance of an object
These problems occur because a bug exists in the .NET Framework 1.1.
This software update corrects these two problems that affect the
System.Collections.Queue class in the Microsoft .NET Framework version 1.1.

To work around these problems, use one of the following methods, depending on the problem that you are experiencing:
- Problem 1 only
Call the TrimToSize method again after you call the Dequeue method. If you do this, later calls to the Enqueue method will work correctly. - Problem 1 and problem 2
Create a new queue that is based on the old queue. For example, use the following structure: You will not experience these problems when you use the new queue instead of the old queue.
The suitability of these workarounds depends on your application's requirements. These workarounds work well if you are using
Queue objects that contain few items, and you are not using the
Queue objects in multiple parts of your application. However, if your
Queue objects contain many items, these workarounds may significantly affect your application's performance.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
