What are the field/method access levels (specifiers) and class access levels?

There are 5 access specifiers totally in C#

Explanation:

In C# there are 5 different access specifiers.

1. Private

2. Protected

3. Internal

4. Protected Internal

5. Public

Fields or methods can have all the access modifiers, where as classes can have only 2 (internal, public) of the 5 access specifiers.

I have explained the usage of each access modifier below.

Private:

Private members are available only with in the containing type.

Public:

Public members are available any where. There is no restriction.

Internal: Internal members are available anywhere in the containing assembly.

Protected:

Protected Members are available, with in the containing type and to the types that derive from the containing type.

Protected Internal:

These are available anywhere within containing assembly and from within a derived class in any another assembly.
