What are finalizers in C#?

Finalizers in C# are used to destruct instances of classes. With that, you can also use it to release resources.

Here are some of the key points about Finalizers −

• Only one finalizer is allowed for a class
• You cannot inherit or overload Finalizers
• A finalizer cannot have parameters
• Finalizers invoke automatically

Finalizers in C# are declared like destructors. Let’s say the class name is Demo, therefore, the following would be our finalizer −

~Demo() {
   //
}

The finalizer declaration is prefixed with a tilde before the class name.
