All types and type members have an accessibility level. The accessibility level controls whether they can be used from other code in your assembly or other assemblies. An assembly is a .dll or .exe created by compiling one or more .cs files in a single compilation.
Definitions of Access Modifiers for C#:
- public: Code in any assembly can access this type or member. The accessibility level of the containing type controls the accessibility level of public members of the type.
- private: Only code declared in the same
class or struct can access this member.
- protected: Only code in the same
class or in a derived class can access this type or member.
- internal: Only code in the same assembly can access this type or member.
- protected internal: Only code in the same assembly or in a derived class in another assembly can access this type or member.
- private protected: Only code in the same assembly and in the same class or a derived class can access the type or member.
- file: Only code in the same file can access the type or member.
The record modifier on a type causes the compiler to synthesize extra members. The record modifier doesn't affect the default accessibility for either a record class or a record struct.
