How do you Dispose a method in C#?
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.
Can we call Dispose method in C#?
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()) { }
How do you Dispose of unmanaged resources in C#?
Normally such unmanaged resources will be freed in two places:
- The Dispose() method. This should be the normal way that you dispose unmanaged resources.
- The Finalizer . This is a last-resort mechanism. If a class has a finalizer it will be called by the Garbage Collector when it cleans up a dead object.

Does .NET automatically call Dispose ()?
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.
When should I use Dispose?
When an object implements IDisposable you should call Dispose (or Close , in some cases, that will call Dispose for you). You normally do not have to set objects to null , because the GC will know that an object will not be used anymore.
What is the purpose of Dispose?
Dispose improves performance and optimizes memory by releasing unmanageable objects and scarce resources, like Graphics Device Interface (GDI) handles used in applications with restricted Windows space. The Dispose method, provided by the IDisposable interface, implements Dispose calls.
What is the difference between dispose () and Finalize ()?
Finalize is the backstop method, called by the garbage collector when it reclaims an object. Dispose is the “deterministic cleanup” method, called by applications to release valuable native resources (window handles, database connections, etc.)
What is the difference between finally and dispose methods?
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.

In the overload, the disposing parameter is a Boolean that indicates whether the method call comes from a Dispose method (its value is true) or from a finalizer (its value is false). The body of the method consists of two blocks of code: A block that frees unmanaged resources.
