如何将格式化的电子邮件地址解析为显示名称和电子邮件地址? [英] How to parse formatted email address into display name and email address?
问题描述
给定电子邮件地址:Jim"
Given the email address: "Jim" <jim@example.com>
如果我尝试将其传递给 MailAddress，则会出现异常:
If I try to pass this to MailAddress I get the exception:
指定的字符串不是电子邮件地址所需的格式.
The specified string is not in the form required for an e-mail address.
如何在 C# 中将此地址解析为显示名称 (Jim) 和电子邮件地址 (jim@example.com)?
How do I parse this address into a display name (Jim) and email address (jim@example.com) in C#?
我正在寻找 C# 代码来解析它.
I'm looking for C# code to parse it.
我发现 MailAddress 抛出了异常，因为我在电子邮件地址字符串的开头有一个空格.
I found that the exception was being thrown by MailAddress because I had a space at the start of the email address string.
推荐答案
如果您想手动解析电子邮件地址，您需要阅读 RFC2822 (https://tools.ietf.org/html/rfc822.html#section-3.4).3.4 节讨论地址格式.
If you are looking to parse the email address manually, you want to read RFC2822 (https://tools.ietf.org/html/rfc822.html#section-3.4). Section 3.4 talks about the address format.
但是正确解析电子邮件地址并不容易，MailAddress 应该能够处理大多数情况.
But parsing email addresses correctly is not easy and MailAddress should be able to handle most scenarios.
根据 MailAddress 的 MSDN 文档:
According to the MSDN documentation for MailAddress:
http://msdn.microsoft.com/en-us/library/591bk9e8.aspx
它应该能够解析带有显示名称的地址.他们以 "Tom Smith 为例.也许引号是问题?如果是这样，只需去掉引号并使用 MailAddress 解析其余部分.
It should be able to parse an address with a display name. They give "Tom Smith <tsmith@contoso.com>" as an example. Maybe the quotes are the issue? If so, just strip the quotes out and use MailAddress to parse the rest.
string emailAddress = "\"Jim\" <jim@example.com>";
MailAddress address = new MailAddress(emailAddress.Replace("\"", ""));
如果可以避免，手动解析 RFC2822 不值得麻烦.
Manually parsing RFC2822 isn't worth the trouble if you can avoid it.
