[Mono-list] C sharp syntax [OT?]

[Sanin Saracevic]

Hi.
According to C-sharp specification (ftp://ftp.ecma.ch/ecma-st/Ecma-334.pdf,
Section 14.2.1 Operator precedence and associativity) both member access (.)
and element access([]) operators belong to the category of primary
operators. Page 139.2 goes on to state that in case of "two operators with
the same precedence, the associativity of the operators controls the order
in which the operations are performed." Since binary operators are
left-associative, it seems clear that the expression of a form E.I[A] is
evaluated from left to right, in which case the original code in question
should compile. Sections 14.5.4 Member access and 14.5.6 Element access have
more information about resolving statements of a form E.I[A]. Am I missing
something here? BTW,MS c# compiler will accept the original statement with
no complaints.

P.S. I have been following your efforts for some time and can say only best
about it. Keep it up.

Sincerely,
Sanin Saracevic

    Change it to the following:

    IPEndPoint ipend = new IPEndPoint( (host.AddressList)[0], 23);

Your statement reads the following:

    IPEndPoint ipend = new IPEndPoint( host.(AddressList[0]), 23);

    which is invalid.
