Array element access

Array elements are accessed using element-access expressions (14.5.6.1) of the form A[I1, I2, ..., IN], where A is an expression of an array type and each IX is an expression of type int, uint, long, ulong, or of a type that can be implicitly converted to one or more of these types. The result of an array element access is a variable, namely the array element selected by the indices.
The elements of an array can be enumerated using a foreach statement (15.8.4).
