Query regarding static class in c#

Hi all I just wanted to know whether a static class which inherits another class, can have access to the parent classe's non static members or not? Please help. Thanks in advance.

A static class can't inherit from any classes or implement any interfaces.

A static class does implicitly inherit from Object, though. But since it's (also implicitly) abstract you can never have any instances of it, and so can never call any instance methods in Object. Also, it's (implicitly) sealed, and as such cannot have subclasses that would be instantiatable. As a corollary to these characteristics, it can't be used to type any variables, fields or parameters; and it can't be used as a type parameter (if these were possible, null would be the only valid value for such references).

Given all this, a static class does not look like a class at all, and I think would be better represented as a module.

static class cannot inherited .

I think you can go with the same concept with SingleTon class and you can inherit the same.

A static class is basically the same as a non-static class, but there is one difference: a static class cannot be instantiated. In other words, you cannot use the new keyword to create a variable of the class type

How should that work? A static class cannot be instantiated and therefor it will never have access to any non static members.

A static class cannot inherit or implement any class or interface.

The point of inheriting or implementing a class or interface is to allow instances of your class to be used as the base type.
Since static classes cannot have instances, there's no point.
