C# Language Specification

Struct modifiers

A struct-declaration may optionally include a sequence of struct modifiers:

struct-modifiers:
struct-modifier
struct-modifiers struct-modifier

struct-modifier:
new
public
protected
internal
private

It is a compile-time error for the same modifier to appear multiple times in a struct declaration.

The modifiers of a struct declaration have the same meaning as those of a class declaration (§10.1).

2. Partial modifier

The partial modifier indicates that this struct-declaration is a partial type declaration. Multiple partial struct declarations with the same name within an enclosing namespace or type declaration combine to form one struct declaration, following the rules specified in §10.2.

3. Struct interfaces

A struct declaration may include a struct-interfaces specification, in which case the struct is said to directly implement the given interface types.

struct-interfaces:
: interface-type-list

Interface implementations are discussed further in §13.4.
