使用asp.net c＃发送带有多个附件的电子邮件

Question

I am trying to send attachment using following code. But i keep getting error Could not find a part of the path .

I am Calling sendEmail function from ApplyForJob.aspx.cs file which is in under folder App_Code/Helper.cs

Below is the part of SendEmail function

        // Create a new Smpt Client 
        var mailclient = new SmtpClient();

        System.Net.Mail.Attachment attachment1;
        attachment1 = new System.Net.Mail.Attachment(HttpContext.Current.Server.MapPath("~/App_Data/uploads/" + am1));
        mail.Attachments.Add(attachment1);

I have changed path to ~/App_Data/uploads/" + am1 App_Data/uploads/" + am1 ../App_Data/uploads/" + am1

But none of the options seem to be working.

How can i make path correctly point towards file which is stored in App_Data/Uploads/

Problem was resolved by using

HttpContext.Current.Request.MapPath

Answer 2

您需要使用

  Server.MapPath("Path as String")

Answer 3

This will locate the Example.xml file in the App_Data folder (App_Data is a good place to put data files.)

attachment1 = new System.Net.Mail.Attachment(HttpContext.Current.Server.MapPath("~/App_Data/Example.xml"));

This will locate the Example.txt file in the root directory. This can be used in a file in any directory in the application.

attachment1 = new System.Net.Mail.Attachment(HttpContext.Current.Request.MapPath("~/Example.txt"));
