ASP.NET access modifiers

/*By Jiangong SUN*/

public


The type or member can be accessed by any other code in the same assembly or another assembly that references it. 

It is accessible for all.


private


The type or member can only be accessed by code in the same class or struct.


protected


The type or member can only be accessed by code in the same class or struct, or in a derived class.


internal


The type or member can be accessed by any code in the same assembly, but not from another assembly.


protected internal


The type or member can be accessed by any code in the same assembly, or by any derived class in another assembly.

A combination of protected and internal.  This makes the member visible within the same assembly and also makes the member visible to an inheriting class. An inheriting class does not need to be in the same assembly to access the member.

C# default access modifier is : internal
