Why do we use keyword in C#?
using (C# Reference) The using keyword has three major uses: The using statement defines a scope at the end of which an object will be disposed.
The using directive creates an alias for a namespace or imports types defined in other namespaces.
The using static directive imports the members of a single class..
Why do we need destructor in C#?
In c#, Destructor is a special method of a class and it is used in a class to destroy the object or instances of classes. The destructor in c# will invoke automatically whenever the class instances become unreachable. … In c#, destructors can be used only in classes and a class can contain only one destructor.
What is serialization in C#?
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
What is difference between final finally and finalize?
Final class can’t be inherited, final method can’t be overridden and final variable value can’t be changed. Finally is used to place important code, it will be executed whether exception is handled or not. Finalize is used to perform clean up processing just before object is garbage collected. Final is a keyword.
How many times Finalize method is called?
“finalize” method is always called exactly once before the first attempt of the object getting garbage-collected.
What is finalization C#?
In this article Finalizers (which are also called destructors) are used to perform any necessary final clean-up when a class instance is being collected by the garbage collector.
When Finalize method is called 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.
Why finalize () method is used?
finalize() method is a protected and non-static method of java. lang. … This method is used to perform some final operations or clean up operations on an object before it is removed from the memory. you can override the finalize() method to keep those operations you want to perform before an object is destroyed.
What do we write in finalize block?
The finalize() method is a pre-defined method in the Object class and it is protected. The purpose of a finalize() method can be overridden for an object to include the cleanup code or to dispose of the system resources that can be done before the object is garbage collected.
What is difference between Finalize and Dispose in C#?
The main difference between dispose() and finalize() is that the method dispose() has to be explicitly invoked by the user whereas, the method finalize() is invoked by the garbage collector, just before the object is destroyed.
What is using () in C#?
The C# using statement defines a boundary for the object outside of which, the object is automatically destroyed. … The objects specified within the using block must implement the IDisposable interface. The framework invokes the Dispose method of objects specified within the “using” statement when the block is exited.
What is namespace C#?
Namespaces are used in C# to organize and provide a level of separation of codes. They can be considered as a container which consists of other namespaces, classes, etc. A namespace can have following types as its members: Namespaces (Nested Namespace) Classes.
