To attach the file from Local Machine to SharePoint ListItem as an attachment, Import the System.IO namespace to use the Stream Class to read the file contents.
Use System.Web.UI.WebControls.FileUpload control is named as fileUpload in code.
Sample code for uploading the file from Local Machine to ListItem attachments as follows,
//Check the FileUpload control has the file
if (fileUpload.PostedFile != null)
{item = list.Items.Add();
item[“Title”] = fileUpload.FileName;
//Read the Contents from the file in Local machine
Stream fs = fileUpload.PostedFile.InputStream;
byte[] fileContents = new byte[fs.Length];
fs.Read(fileContents, 0, (int)fs.Length);
fs.Close();
// Add the file to the ListItem as an Attachment
SPAttachmentCollection attachments = item.Attachments;
string fileName = Path.GetFileName(fileUpload.PostedFile.FileName);
attachments.Add(fileName, fileContents);
item.Update();
}
