使用C＃发送邮件时出现问题 [英] Problem in sending the mail using C#

问题描述

全部好，



i我使用SMTP发送电子邮件，并通过文件上传控件将附件添加到电子邮件中，并通过邮件发送附件，但是对于第一个时间，如果我通过电子邮件发送文件邮件正确，但发送邮件后，如果我通过文件上传控件添加相同的文件，我会得到错误

该进程无法访问文件'D：\Program Files \Express\Temp \ SupportAttachments\ support.txt'，因为它正被另一个进程使用。







我将文件从上传控件上传到网格，从网格中挑选文件并附加到邮件中。 />


这是我的代码：

HI ALL,

i am sending the email using SMTP and adding the attachements to the email from file upload control and sending the attachements with mail,but for the first time if i am sending the file through email the mail is going correctly but after sending the mail, for the secoind time if i am adding the same file through file upload control i am getting theerror
"The process cannot access the file 'D:\Program Files\Express\Temp\SupportAttachments\support.txt' because it is being used by another process.
"


I am uploading the files from upload control to grid an dfrom grid picking the files and attaching to the mail..

here is my code:

foreach (GridViewRow gvrow in grdfiledetails.Rows)
            {
                Label lbl = (Label)gvrow.FindControl("lblfilename");
                string SupportAttachmentFilePath = "D:\\Program Files\\Duck Creek Technologies\\Express\\Temp\\SupportAttachments";
                SupportAttachmentFilePath += "\\" + lbl.Text;
                string BasePathValue = lbl.Text;
                 firstAttachment = new Attachment(SupportAttachmentFilePath);
                firstAttachment = new Attachment(SupportAttachmentFilePath, MediaTypeNames.Application.Octet);
                mail.Attachments.Add(firstAttachment);
                //attach1 = BasePathValue;
                //firstAttachment.Dispose();
            }

            try
            {
                SmtpServer.Send(mail);}<pre lang="c#">

请帮助该怎么做

Please help what to do

推荐答案

以前的流程尚未完成，这就是错误，



结束这个过程需要时间



r发送电子邮件后你就可以从代码中结束这个过程了。



它可以帮助你...

Previous process has not been yet completed, thats y it is getting error,

it takes time to end the process

r else after sending email you end the process from code.

it may helps you...

变量 firstAttachment 在foreach循环之外声明 - 改变它，在里面声明它。接下来，仅创建一次附件;还要确保没有重复项（两个文件名相同的附件）！

The variable firstAttachment is declared outside the foreach loop - change that, declare it inside. Next, create the attachment only once; also make sure there are no duplicates (two attachments with the same filename)!
