Tuhin Paul · Answer

There are five access modifiers in C#: Public: Public members are visible to all other classes and assemblies. They can be accessed from anywhere including outside the assembly in which they are declared. Private: Private members are only visible within the same class. They cannot be accessed outside of the class. Protected: Protected members are visible within the same class and any derived classes. They cannot be accessed outside of the class hierarchy. Internal: Internal members are only visible within the same assembly. They cannot be accessed outside of the assembly. Protected Internal: Protected internal members are visible within the same assembly and any derived classes whether they are in the same assembly or not.

public There are no restrictions on accessing public members. private Access is limited to within the class definition. This is the default access modifier type if none is formally specified protected Access is limited to within the class definition and any class that inherits from the class internal Access is limited exclusively to classes defined within the current project assembly protected internal Access is limited to the current assembly and types derived from the containing class. All members in current project and all members in derived class can access the variables. private protected Access is limited to the containing class or types derived from the containing class within the current assembly.

Hi Agree with Vulpes there are five access modifier. Please refer https://msdn.microsoft.com/en-us/library/ms173121.aspx hope this will help you.

Vulpes · Answer

There's also a fifth access modifer: protected internal. This is the union of protected and internal access. The CLR supports a sixth access modifier known as 'famandassem' which is the intersection of protected and internal access but this isn't supported by either C# or VB.NET. However it is supported in C++/CLI where it's called 'private protected'.
