推荐答案
阅读下面的SharePoint列表附件字段值：
Read the SharePoint list attachment field value like below:
List<SPFile> _fileList = null;
SPWeb myweb = SPContext.Current.Web;
SPSite mysite = SPContext.Current.Site;
SPList mylist = SPContext.Current.List;
SPListItem myitem = SPContext.Current.ListItem;
SPAttachmentCollection myattach = myitem.Attachments;
if (myattach.Count != 0)
{
myweb.AllowUnsafeUpdates = false;
List<SPFile> lstSPFile = null;
SPSecurity.RunWithElevatedPrivileges(delegate
{
using (SPSite oSite = new SPSite(myitem.ParentList.ParentWeb.Site.ID))
{
using (SPWeb oWeb = oSite.OpenWeb(myitem.ParentList.ParentWeb.ID))
{
SPFolder folder = myitem.ParentList.RootFolder.SubFolders["Attachments"].SubFolders[myitem.ID.ToString()];
lstSPFile = new List<SPFile>();
foreach (SPFile file in folder.Files)
{
lstSPFile.Add(file);
}
_fileList = lstSPFile;
}
}
});然后下载文件流数据并添加到&#bsp; mailMessage.Attachments：
Then download the the file stream data and add to mailMessage.Attachments:
string smtpServer = SPAdministrationWebApplication.Local.OutboundMailServiceInstance.Server.Address;
string smtpFrom = SPAdministrationWebApplication.Local.OutboundMailSenderAddress;
MailMessage mailMessage = new MailMessage(smtpFrom, "email@email.com");
mailMessage.Body = "body body body body body body body body body ";
mailMessage.Subject = "subject subject subject";
foreach(var file in _fileList){
WebClient webClient = new WebClient();
//Supply the WebClient with the network credentials of our user
webClient.Credentials = CredentialCache.DefaultNetworkCredentials;
string mypath = "http://server/" + file;
//Download the byte array of the file
byte[] data = webClient.DownloadData(mypath);
MemoryStream memoryStreamOfFile = new MemoryStream(data);
mailMessage.Attachments.Add(new System.Net.Mail.Attachment(memoryStreamOfFile, file.Name.ToString()));
}
//Create the SMTP client object and send the message
SmtpClient smtpClient = new SmtpClient(smtpServer);
smtpClient.Send(mailMessage);
}
谢谢
