我工作的这是一个使用系统的应用.Net.Mail.MailAddress 和朋友发送电子邮件。这是否解析器实现全 RFC5322 的子集或什么？在MSDN不是很即将举行的关于这一主题。

I'm working on an app that's using System.Net.Mail.MailAddress and friends for sending emails. Does that parser implement the full RFC5322 or a subset or what? The MSDN is not very forthcoming on this topic.

任何提示AP preciated。

Any hints appreciated.

推荐答案

我已经写了一个小片段来测试功能：

I've wrote a little snippet to test the function:

foreach (int i in Enumerable.Range(32,128-32))
{
    char c = (char)i;
    string addr = String.Format("par.t1{0}pa.r{0}t2@example.com", c);
    try
    {
        var mailAddr = new MailAddress(addr);
    }
    catch
    {
        Console.WriteLine("MailAddress failed '{0}' ({1}): {2}", c, i, addr);
    }
}

随着3.5 SP1以下结果：

With the following results on 3.5 SP1:

MailAddress failed ' ' (32): par.t1 pa.r t2@example.com
MailAddress failed '"' (34): par.t1"pa.r"t2@example.com
MailAddress failed '(' (40): par.t1(pa.r(t2@example.com
MailAddress failed ')' (41): par.t1)pa.r)t2@example.com
MailAddress failed ',' (44): par.t1,pa.r,t2@example.com
MailAddress failed ':' (58): par.t1:pa.r:t2@example.com
MailAddress failed ';' (59): par.t1;pa.r;t2@example.com
MailAddress failed '<' (60): par.t1<pa.r<t2@example.com
MailAddress failed '>' (62): par.t1>pa.r>t2@example.com
MailAddress failed '@' (64): par.t1@pa.r@t2@example.com
MailAddress failed '[' (91): par.t1[pa.r[t2@example.com
MailAddress failed '' (92): par.t1pa.rt2@example.com
MailAddress failed ']' (93): par.t1]pa.r]t2@example.com
MailAddress failed '⌂' (127): par.t1⌂pa.r⌂t2@example.com

此外，它似乎不支持引用字符串本地部分，如嗒嗒@ example.com 。

我不认为一个验证器可以接受任何减少变得不可用了。

I don't think a validator could accept any less before becoming unusable.
