A list item in SharePoint can have multiple attachments. Below is a code snippet in c#.Net to add an attachment to a list item programmatically.

This example demonstrates how a file, uploaded through a file upload control is added as an attachment to a list item.

using (SPSite oSPsite = new SPSite(http://website Url/))

{

using (SPWeb oSPWeb = oSPsite.OpenWeb())

{

oSPWeb.AllowUnsafeUpdates = true;

// Fetch the List

SPList list = oSPWeb.Lists["MyList"];

// Get the List item

SPListItem listItem = list.GetItemById(1);

// Get the Attachment collection

SPAttachmentCollection attachmentCollection = listItem.Attachments;

Stream attachmentStream;

Byte[] attachmentContent;

// Get the file from the file upload control

if (this.fileDocAttach.HasFile)

{

attachmentStream = this.fileDocAttach.PostedFile.InputStream;

attachmentContent = new Byte[attachmentStream.Length];

attachmentStream.Read(attachmentContent, 0, (int)attachmentStream.Length);

attachmentStream.Close();

attachmentStream.Dispose();

// Add the file to the attachment collection

attachmentCollection.Add(this.fileDocAttach.FileName, attachmentContent);

}

// Update th list item

listItem.Update();

oSPWeb.AllowUnsafeUpdates = false;

}
