Paragraph 11 A pointer-indirection-expression consists of an asterisk (*) followed by a unary-expression. pointer-indirection-expression : * unary-expression
Paragraph 21 The unary * operator denotes pointer indirection and is used to obtain the variable to which a pointer points.
Paragraph 31 The result of evaluating *P, where P is an expression of a pointer type T*, is a variable of type T. 2 It is a compile-time error to apply the unary * operator to an expression of type void* or to an expression that isn't of a pointer type.
Paragraph 41 The effect of applying the unary * operator to a null pointer is implementation-defined. 2 In particular, there is no guarantee that this operation throws a System.NullReferenceException.
Paragraph 51 If an invalid value has been assigned to the pointer, the behavior of the unary * operator is undefined. [Note: Among the invalid values for dereferencing a pointer by the unary * operator are an address inappropriately aligned for the type pointed to (see example in §25.4), and the address of a variable after the end of its lifetime. end note]
Paragraph 61 For purposes of definite assignment analysis, a variable produced by evaluating an expression of the form *P is considered initially assigned (§12.3.1).
