What is difference between destructor and finalize?
In C#, writing a destructor is the way to override the Finalize method. So there’s really no difference between the two. In short: Basically you’ll implement Dispose method when you want to dispose managed and/or unmanaged resources.
What is the use of finalize in C#?
The Finalize method is used to perform cleanup operations on unmanaged resources held by the current object before the object is destroyed. The method is protected and therefore is accessible only through this class or through a derived class.
What is IDisposable in C #?
IDisposable is an interface that contains a single method, Dispose(), for releasing unmanaged resources, like files, streams, database connections and so on.
Why do we use IDisposable in C#?
IDisposable is often used to exploit the using statement and take advantage of an easy way to do deterministic cleanup of managed objects. The purpose of the Dispose pattern is to provide a mechanism to clean up both managed and unmanaged resources and when that occurs depends on how the Dispose method is being called.
Why would you need the IDisposable?
in a class, you should implement IDisposable and overwrite the Dispose method to allow you to control when the memory is freed. If not, this responsibility is left to the garbage collector to free the memory when the object containing the unmanaged resources is finalised.
What is the difference between finalize And finally?
The basic difference between final, finally and finalize is that the final is an access modifier, finally is the block in Exception Handling and finalize is the method of object class. final is the keyword and access modifier which is used to apply restrictions on a class, method or variable.
What is difference between the throw and throw ex in net?
throw is used to throw current exception while throw(ex) mostly used to create a wrapper of exception. throw(ex) will reset your stack trace so error will appear from the line where throw(ex) written while throw does not reset stack trace and you will get information about original exception.
What is the difference between throw and throws?
The throw keyword is used to throw an exception explicitly. It can throw only one exception at a time. The throws keyword can be used to declare multiple exceptions, separated by a comma.
Do I need a finaliser for an object with IDisposable?
No, you are correct, if your object holds an object that holds an unmanaged resource then you should implement IDisposable so that you can call its Dispose on your Dispose, but you don’t need a finaliser as its finaliser will deal with that matter.
What is the use of finalize method in ididisposable interface?
IDisposable interface expose Dispose method where code to release unmanaged resource will be written. Finalize method also called destructor to the class. Finalize method can not be called explicitly in the code. Only Garbage collector can call the the Finalize when object become inaccessible.
What is the difference between disposemethods dispose() and finalize()?
Methods dispose() and finalize() are the methods of C# which are invoked to free the unmanaged resources held by an object. The dispose() method is defined inside the interface IDisposable whereas, the method finalize() is defined inside the class object.
What happens if the finalize method is not called?
The finalize method has not been called. Then the finalize method is called. So when we close the exe then garbage collector calls the finalize method. Even if you have implemented the IDisposable dispose method but you forgot to call the dispose method then it will call the finalize method.
