Recommendation 108: Identify the type as sealed

Sealed can prevent a type from being inherited by another type. The code is as follows:

    Sealed class SampleClass    {            }    class  otherclass:sampleclass    {            }

This Code hints:

"Cannot derive from sealed type SampleClass. ”

Modifying a type to sealed effectively controls the depth of the inheritance. A type should be converted into a sealed class in time if it is certain that it is not necessary to be inherited.

It is also not necessary to declare the protected method in a sealed class.

In. NET, string is the sealed class.
