    The default accessibility for a type is internal, but the default accesibility of that type's members depends on the type.

    Generally speaking, members of a class are private by default, where as members of a struct are public by default. This varies by language; default struct access modifiers for C++ are public, where as for C#, they are private.

    From The C# Programming Language, Third Edition by Anders Hejlsberg et al, section 10.3.5 ("Class Members - Access Modifiers") on page 434:

    A class-member-declaration can have any one of the five possible kinds of declared accessibility (§3.5.1): public, protected internal, protected, internal, or private. Except for the protected internal combination, it is a compile-time error to specify more than one access modifier. When a class-member-declaration does not include any access modifiers, private is assumed. [Emphasis mine]

    And then in section 11.2 ("Struct Members") on page 539:

    Except for the differences noted in §11.3, the descriptions of class members provided in §10.3 through §10.14 apply to struct members as well.

    Section 11.3 does not mention anything about access modifiers, so my reading of this implies that members of a struct without an access modifier are also private by default. This corresponds with what MSDN says and with my own experience.
