格式化字符串作爲電子郵件地址

這從項目業主返回的電子郵件地址：格式化字符串作爲電子郵件地址

var selectEmailData = "SELECT User.Email FROM Projects INNER JOIN User ON Projects.ProjectOwner = User.UserId WHERE [email protected]"; 
var dataEmail = db.Query(selectEmailData, ProjectId); 

@foreach (var row in dataEmail) 
{ 
    @row.Email 
}

但是，當我嘗試這樣做：

var mailTo = dataEmail.ToString();

將一封電子郵件：

WebMail.Send(
    to: mailTo, 
    subject: "Hello there!", 
    body: "Your project is ready." 
);

我得到了這個：指定的字符串不是電子郵件地址所需的格式。

這段代碼有什麼問題？

所以什麼'mailTo'是什麼？ –

User.Email的價值是什麼？ – ChrisF

'mailTo'和'User.Mail'是來自以下地址的郵件地址：'@ row.Email' – Mendelsohn

我敢肯定...

var dataEMail = db.Query(…) would return a collection not a string.

SO ...

var mailTo = dataEmail.ToString();

將返回類似「System.Collections.Generic ......」

我猜你可能想要像這樣的東西

var selectEmailData = "SELECT User.Email FROM Projects INNER JOIN User ON Projects.ProjectOwner = User.UserId WHERE [email protected]"; 
var allEmails = db.Query(selectEmailData, ProjectId); 

@foreach (var row in allEmails) 
{ 
    WebMail.Send(
    to: @row.Email, 
    subject: "Hello there!", 
    body: "Your project is ready." 
)

驗證？

其他方式：

try 
{ 
MailAdress email = new MailAddress(<enter here string>); 
} 
catch (FormatException fe) 
{ 
//Bad email 
}
