c# - Why does every class in .NET inherit from Object? -

I can not understand it ...

Why do they need a similar basis?

The question accepts a lie, they do not need a common base type This option was not out of necessity, it was carried out by the desire to provide the best value for the customer.

When designing a type of system, or something else for that matter, sometimes you reach the decision point - you do not have x x. When this is the common base type or a normal base type, then we weigh the benefits and benefits of x to determine the net value, and then you take advantage of the cost and profit-X to determine the net value , And you go with one that was of high value. There is a huge increase in the prices of the benefits of a common base type, and pure pure profit by it is greater than the net profit of the common base type. So we choose a common base type.

This is a very vague answer. If you want a more specific answer, try asking a more specific question.
