Finalize C#
1 I am new to c# and am trying to dispose of objects taking up large amounts of memory as I've run memory profiling and need to dispose of some resources and call the finalize method for GC. However IDisposable cant implement my class why is this? and how should I implement IDispose to my class? public class CellItem: IDisposable { public int MedicationDispenseId { get; set; } public Enumerations.Timeslot c# finalizer Timeslot { get; set; } public DateTime DateAdministered { get; set; } public void dispose() { if (this.MedicationDispenseId != null ) { this.dispose(); } if (this.Timeslot != null) { this.dispose(); } if (this.DateAdministered != null) { this.dispose(); } } } c# memory garbage-collection share|improve this question asked Aug 23 '13 at 10:07 user2708073 62313 Even if you correct the casing, calling this.Dispose inside Dispose is a bad idea. int and DateTime don't implement IDisposable, so you probably shouldn't implement IDisposable on CellItem at all. –Henrik Aug 23 '13 at 10:44 True. Thanks After some reading I've come to the same conclusion. –user2708073 Aug 23 '13 at 12:46 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted C# is case-sensitive, you want to name your methods starting with capital letter, i.e. dispose => Dispose Also have a look at Implement IDisposable correctly and yet another good answer from John Skeet. share|improve this answer answered Aug 23 '13 at 10:11 oleksii 23.6k650103 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post a
Framework > Common Language Runtime Internals and Architecture Question 0 Sign in to vote Hi Im using VS2005 dispose vs finalize C# I want to use the using statement with a class
C# Destructor
that I have created. I m doing something simple like this string Var = String.empty. using (clsHome
C# Using
Home = new clsHome){ Var = Home.MyMethod(); } 1. Im getting an exception saying that clsHome need to be implicit convertible to IDisposable 2. When I inherit in http://stackoverflow.com/questions/18400144/shared-cellitem-does-not-implement-interface-member-system-idisposable-dispose my class clsHome : IDisposable and run I get the error: clsHome' does not implement interface member 'System.IDisposable.Dispose() I'm implementin the Dispose() like this inside my class protected void Dispose(bool disposing){
if (disposing && (components != null)){ components.Dispose();} base.Dispose(disposing); } and I still get the error Question: How Should I implement the Dispose() method? thanks https://social.msdn.microsoft.com/Forums/vstudio/en-US/4586dbfc-4c80-4848-a8af-dabadafed03a/about-implementing-idisposable-for-use-using-statement?forum=clr ky Wednesday, November 29, 2006 10:07 PM Reply | Quote Answers 0 Sign in to vote Hi Kymaita You'll need to implement IDisposable's public method: public void Dispose(), like this:class Foo : IDisposable{...public void Dispose(){ Dispose(true); GC.SuppressFinalize(this); }...}See http://msdn2.microsoft.com/en-us/library/fs2xkftw.aspx for more information about Dispose.

By convention, this method is used for all tasks associated with freeing resources held by an object, or preparing an object for reuse.Warning If you are using a class that implements the IDisposable interface, you should call its Dispose implementation when you are finished using the class. For more information, see the "Using an object that implements IDisposable" section in the IDisposable topic. When implementing this method, ensure that all held resources are freed by propagating the call through the containment hierarchy. For example, if an object A allocates an object B, and object B allocates an object C, t

It is a version breaking change to add the IDisposable interface to an existing class, as it changes the semantics of the class. [Note: IDisposable contains the System.IDisposable.Dispose method. The consumer of an object should call this method when the object is no longer needed. The IDisposable interface is generally provided for the release of unmanaged resources that need to be reclaimed in some order or time dependent manner. It is important to note that the actual release of these resources happens at the first call to System.IDisposable.Dispose for any given object that supports this interface. Programmers should take care to pair the creation of objects that implement IDisposable with at most one invocation of the Dispose method. Though it is legal to invoke Dispose more than once, if this happens it might indicate the presence of a bug since such an object is usually rendered otherwise unusable after the first Dispose invocation. ] See Also System Namespace Members IDisposable Methods IDisposable.Dispose Method IDisposable.Dispose Method void Dispose(); Summary Performs application-defined tasks associated with freeing or resetting resources. Description [Note: This method is, by convention, used for all tasks associated with freeing resources held by an object, or preparing an object for reuse. When implementing the System.IDisposable.Dispose method, objects should seek to ensure that all held resources are freed by propagating the call through the containment hierarchy. For example, if an object A allocates an object B, and B allocates an object C, then A's System.IDisposable.Dispose implementation should call System.IDisposable.Dispose on B, which should in turn call System.IDisposable.Dispose on C. Objects should also call the System.IDisposable.Dispose method of their base class if the base class impleme
