发送存储在变量中的邮件

Question

我在SQL中有一个简单的表（MyEmail），需要发送一些电子邮件，例如：

ID  Email
1   [email protected]
2   [email protected]
3   [email protected]
4   [email protected]

我创建了一个存储过程（GetAddress）来收集它们，以便稍后将它们存储到变量中：

 SELECT  Email
 FROM dbo.MyEmai

我需要C＃部分代码的帮助：

var MyEmails = new List<Email>();
                    SqlCommand cmdEmails = new SqlCommand("GetAddress", connection);
                    SqlDataReader rdEmails = cmdEmails.ExecuteReader();
                    while (rdEmails.Read())
                    {
                        MyEmails.Add(new Email() { MyEmails = rdEmails[0].ToString() }); // as an example 
                    }

此代码返回列表，但电子邮件位于Web Application.MyPage下面。电邮姓名。我的电子邮件回复：

WebApplication.MyPage.Email > [email protected] 
WebApplication.MyPage.Email > [email protected] ...

我需要删除此WebApplication.MyPage.Email，因此只有电子邮件将首先显示为字符串。

发送电子邮件的代码：

SmtpClient client = new SmtpClient();
                            client.Port = 112;

                            client.Host = "my-smtp";
                            client.Timeout = 10000;
                            client.DeliveryMethod = SmtpDeliveryMethod.Network;
                            client.UseDefaultCredentials = false;

                            client.Credentials = new System.Net.NetworkCredential("[email protected]", "");


                            MailMessage mm = new MailMessage(LocalName, LocalName + MyEmails, "New Mail subject", "This is Email body !");

                            client.Send(mm);

所以因为这个MyEmails有一个错误：错误24参数2：无法从'System.Collections.Generic.List'转换为'string'

有人可以帮我弄这个吗？

提前致谢！

.Net的MailMessage类不接受List作为有效参数。对你的收藏进行抄袭，创建多个mailmessage。

代码看起来应该是这样的

foreach (var emailadressObject in myEmails)
{
// get your emailadres string from your object..
// Bit confusion using a collection MyEmails and a Property in you mail objetc with MyEmails
var emailadresstring = emailadressObject.MyEmails; 
    var message = new MailMessage("[email protected]", emailadresstring, "New Mail subject", "This is Email body !");
// Do you magic with the mail message
 }
