Again, repeat the process to create another class library project with the name AssemblyTwo to our solution. If you have followed the steps correctly, now we should have three projects in the solution explorer as shown in the below image. Now if we build the solution, we should have 3 assemblies generated. Two DLLs and one exe. To locate the physical assembly follow these steps. Now, create a class file with the name AssemblyOneClass.
So, this proofs that the Internal Members access anywhere within the same assembly. Now, create a class file with the name AssemblyTwoClass. Notice, here, we got 2 compiler errors at this point. To do so, please follow the below steps. At, this point all the compiler errors should have gone. Now, uncomment the following line from the AssemblyTwoClass. WriteLine instance. Now, we will get a compiler error as shown in the below image. This proves that internal members are only accessible within the same assembly.
Code outside of the containing assembly cannot access internal members. Protected Internal Members in C can be accessed anywhere within the assembly in which it is declared or from within a derived class in another assembly. So, we can think, it is a combination of Protected and Internal.
If you understood the Protected and Internal access specifiers in C , then this should be very easy to follow. And then, modify the code in the AssemblyTwoClass. As of now, we have discussed how to use access specifiers with the type members. Let see how to use the access specifiers in C with the type. We can use all 5 access specifiers with type members in C but type allows only Internal and Public access specifiers.
It is a compile-time error to use private, protected, and protected internal access specifiers with types. The following code will generate a compiler error stating Elements defined in a namespace cannot be explicitly declared as private, protected, or protected internal.
For more information, see Operator overloading. To set the access level for a class , record , or struct member, add the appropriate keyword to the member declaration, as shown in the following example.
Interfaces declared directly within a namespace can be public or internal and, just like classes and structs, interfaces default to internal access. Interface members are public by default because the purpose of an interface is to enable other types to access a class or struct. Interface member declarations may include any access modifier. This is most useful for static methods to provide common implementations needed by all implementors of a class.
Delegates behave like classes and structs. By default, they have internal access when declared directly within a namespace, and private access when nested. For more information, see the C Language Specification. The language specification is the definitive source for C syntax and usage.

Access modifiers and specifiers are keywords to specify the accessibility of a type and its members. C has 5 access specifier or access modifier keywords; those are private, public, internal, protected and protected Internal. Usage of Access Specifiers private: limits the accessibility of a member to within the defined type, for example if a variable or a functions is being created in a ClassA and declared as private then another ClassB can't access that.
Most DLLs are known to be produced by public class and members written in a. An assembly is the produced. NET Language code C. Hence, if you have a C project that has ClassA, ClassB and ClassC then any internal type and members will become accessible across the classes with in the assembly. In other words any protected type or member becomes accessible when a child is inherited by the parent.
In other cases when no inheritance protected members and types are not visible. Protected internal: is a combination of protected and internal both. A protected internal will be accessible within the assembly due to its internal flavor and also via inheritance due to its protected flavor.
