Question

我在网上找到了asp网站和asp联系表格。它在本地机器上运行完美。

我将它添加到我的服务器以进行实时测试，但它无效。我收到显示错误的显示消息，它说：

System.Security.SecurityException：请求类型的权限 'System.Net.Mail.SmtpPermission，System，Version = 4.0.0.0， Culture = neutral，PublicKeyToken = b77a5c561934e089'失败。在 System.Security.CodeAccessSecurityEngine.Check（对象需求， StackCrawlMark＆安培; stackMark，Boolean isPermSet）at System.Security.CodeAccessSecurityEngine.Check（的CodeAccessPermission cap，StackCrawlMark＆amp; stackMark）at System.Security.CodeAccessPermission.Demand（）at System.Net.Mail.SmtpClient.Initialize（）at System.Net.Mail.SmtpClient..ctor（String host，Int32 port）at contact.btnSubmit_Click（Object sender，EventArgs e）in g：\ pleskvhosts \ myweburl \ httpdocs \ contact.aspx.cs：第33行动作失败的是：Demand失败的第一个权限的类型是：System.Net.Mail.SmtpPermission组件的区域失败的是：MyComputer

有谁知道这意味着什么？

我的contact.aspx.cs代码是

protected void btnSubmit_Click(object sender, EventArgs e)
{
    try
    {
        MailMessage mailMsg = new MailMessage();

        mailMsg.From = new MailAddress(TheirEmail.Text);

        mailMsg.To.Add("myemailaddress@gmail.com");

        mailMsg.IsBodyHtml = true;

        mailMsg.Subject = "Contact Question!";

        mailMsg.Body = "Contact Details" + "<b>Name:</b>" + TheirName.Text + " <br/> <b>Email - address :</b>" + TheirEmail.Text + "<br/> <b>Comments :</b>" + Comments.Text;

        SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);

        mailMsg.Priority = MailPriority.Normal;

        smtp.Credentials = new System.Net.NetworkCredential("myemailaddress@gmail.com", "mypassword");

        smtp.Timeout = 25000;

        smtp.EnableSsl = true;

        smtp.Send(mailMsg);

        TheirEmail.Text = "";
        TheirName.Text = "";
        Comments.Text = "";


        DisplayMessage.Text = "Thank you. Your contact details and feed back has been submitted.";
        DisplayMessage.Visible = true;
    }

    catch (Exception ex)
    {
        DisplayMessage.Text = ex.ToString();
        DisplayMessage.Visible = true;
    }

Answer 1

确保 Web.Config 文件的 trust level 设置为 full ：

<configuration>
  <system.web>
    .....
    <trust level="Full" originUrl=""/>
  </system.web>
</configuration>

例如，如果您使用的是GoDaddy，则必须在 System.Net.Mail.SmtpClient 变量中设置以下内容（例如* smtp *）：

SmtpClient smtp = new SmtpClient("relay-hosting.secureserver.net", 25);
smtp.EnableSsl = false; // check if your ISP supports SSL

您还需要按照 here 这一页面正确配置GoDaddy上的电子邮件。

在某些情况下，如果无法实现full trust，则安全级别较低将不允许您指定SMTP端口。您的ISP指定端口 80 ，但有时您可以使用默认值端口25 如果80不起作用。

Answer 2

这样做.....

List<people> lstPeeps = new List<people>();

foreach (var item in ListBox1.Items)
{
   if (item.Contains("@"))    //This checks to see if it's an email address...                         
       lstPeeps.Add(item as peep.m_sEmail);
   else lstPeeps.Add(item as peep.m_sName);
foreach (var peep in lstPeeps)
    MessageBox.Show(peep.name + "\t" + peep.email);

Asp联系页面在本地工作，但不在服务器上工作
