Dispose Required Field Certificate For Free

Working of dispose() Function To free and reset the resources that are unmanaged like connections to the databases, files, etc., and to perform a cleanup of the memory, we make use of a function called dispose of () function in C#. The dispose() function in C# must implement the IDisposable interface.

The idiom is to declare which objects you are using and then to create a scope for these objects with curly braces. When the close brace is reached, the Dispose( ) method will be called on the object automatically, as illustrated in Example 4-6.

It is always recommended to use Dispose method to clean unmanaged resources. You should not implement the Finalize method until it is extremely necessary. At runtime C#, C++ destructors are automatically Converted to Finalize method.

The Dispose method leaves the Controller instance in an unusable state. After you call Dispose, you must release all references to the Controller instance so that the garbage collector can reclaim the memory that the Controller instance was occupying.

When the close brace is reached, the Dispose( ) method will be called on the object automatically, as illustrated in Example 4-6. In the first part of this example, the Font object is created within the using statement. When the using statement ends, Dispose( ) is called on the Font object.

The Dispose() method The Dispose method performs all object cleanup, so the garbage collector no longer needs to call the objects' Object. Finalize override. Therefore, the call to the SuppressFinalize method prevents the garbage collector from running the finalizer. If the type has no finalizer, the call to GC.

Rule of thumb: if a class implements IDisposable you should always call the Dispose method as soon as you have finished using this resource. Even better wrap it in a using statement to ensure that the Dispose method will be called even if an exception is thrown: using (var reader = conn. ExecuteReader()) {}

Working of dispose() function is as follows: To free and reset the resources that are unmanaged like connections to the databases, files, etc., and to perform a cleanup of the memory, we make use of a function called dispose of () function in C#. The dispose() function in C# must implement the IDisposable interface.

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.

Dispose() will not be called automatically. If there is a finalizer it will be called automatically. Implementing IDisposable provides a way for users of your class to release resources early, instead of waiting for the garbage collector.
