Should I Use IDisposable for Managed and Unmanaged Resources?

The correct use of the IDISPOSABLE interface

Although the interface is mainly used to clean up non -hosting resources, it can also be used to clean up the custody resources, thereby providing additional flexibility and control of resource management.

Use IDISPOSABLE to release memory in time IDisposable

The sample code provided to use the

method to release the hosting resources (

and

objects). This method is very useful when you hope to immediately release memory instead of relying on garbage recychers, which may improve performance. Dispose List<string> However, it is important to note that the Dictionary<string, point> method should be released

Non -host

resources, which may include the handle, database connection or operating system object. The hosting resources will eventually be recycled by the garbage recyrior, so it is not necessary or ideal to release them to release the Dispose method. Release hosting and non -hosting resources Dispose

In order to deal with the cleanup of non -hosting and hosting resources, please consider using the following mode:

Rewriting the

method and call the auxiliary method
1. , pass to indicate that the call is derived from and should be released. Finalize Dispose(Boolean) Rewam true Dispose Method and call
(and
2. to prevent calling the terminal again). Create a IDisposable.Dispose Auxiliary method Dispose(true), this method handles non -hosting resources and optional custody resources to clean up. When the method is called, it is passed into GC.SuppressFinalize(this) to indicate that the hosting resources should not be released.
3. Best Practice Dispose(Boolean) In order to optimize the resources management, please follow the following best practice: Finalize false
Always

Use

to clean up non -hosting resources because they will not be recovered by automatic garbage.

Consider

Use

to clean up the custody resources, if this meets your performance requirements.
• Priority Differential calls Dispose rather than rely on the terminal, because the exact time of the terminal is unpredictable.
• Implement Your own method, even if you do not need to be cleaned up by non -custody resources, because it may be necessary for sub -category or interface implementation. Dispose
• By observing these criteria, you can effectively manage resources, improve performance, and ensure the correct cleaning and disposal of the object.
