gc dispose

1. The Finalize method (in C # is a destructor, the following destructor) is used to dispose of unmanaged resources, and managed resources are automatically reclaimed by the GC. So, we can also differentiate between managed and unmanaged resources. All of the resources that will be automatically reclaimed by GC are managed resources, and resources that cannot be

resource in time, without waiting for the time when the class object is reclaimed. developers of such classes only need to port the code originally written in Finalize to the Dispose (bool disposing) to release unmanaged resources. in Finalize, you only need to simply call "Dispose (false)" (Why is false passed. At this time, we may be confused. Why do we still need a

From: http://www.cnblogs.com/lzhdim/archive/2009/11/04/1595845.html Before learning about finalize and dispose, we need to understand two concepts: managed resources and non-commissioned resources.A. managed resources generally refer to the memory resources controlled by CLR. The management of these resources can be controlled by CLR, such as objects allocated in the program and variables in the scope.B. Non-managed resources are components that the

One, close and dispose of the difference between the two methods When the Close method of the object is called, the object may be reused, and the Dispose method, the object's resource needs to be marked as useless, that is, the object is destroyed and cannot be used again. such as common. NET class library, when the Close method is called, you can reopen a database connection through open, and you can call

TypeDisposeMethod should release all its resources. It should also call its parent typeDisposeMethod to release all resources of the base type. This parent typeDisposeMethod should release all its resources and also call its parent typeDisposeMethod to spread the mode throughout the base type hierarchy. Make sure that resources are always correctly cleared,DisposeThe method should be called for security multiple times without any exception. DisposeThe method should be called for the objects it h

When the garbage collector is started, it is found that the object referenced by fs is useless. (Of course, You can recycle the object when the CLR is disabled .)B. We found that the fs type: FileStream provides the Finalize method, so we call this method first.(Reflector continues as follows)C. The Finali

True (true), you can purge controlled and unmanaged resources, and when isdisposing is false, you can only clear uncontrolled resources. In either case, you can call the base class's Dispose (bool) method so that it clears its own resources.Here's a short example that demonstrates the code framework that you provide when implementing this pattern. The Myresourcehog class demonstrates the code that implements the IDisposable interface, finalizers, and
