SharePoint:如何以编程方式向列表项添加附件? [英] SharePoint: How to add an attachment to a list item programatically?

问题描述

我有以下代码:

  SPList list = web.Lists[this.ListName];
  SPListItem item = list.Items.Add();

现在我想做的是:

   FileInfo[] attachments = attachmentDirectory.GetFiles();
        foreach (FileInfo attachment in attachments)
        {
           // Add the attachment from file system to the list item...

        }

如何将普通文件转换为字节数组?

How do I convert a normal file to a byte array?

推荐答案

 foreach (FileInfo attachment in attachments)
        {
            FileStream fs = new FileStream(attachment.FullName , FileMode.Open,FileAccess.Read);

            // Create a byte array of file stream length
            byte[] ImageData = new byte[fs.Length];

            //Read block of bytes from stream into the byte array
            fs.Read(ImageData,0,System.Convert.ToInt32(fs.Length));

            //Close the File Stream
            fs.Close();

            item.Attachments.Add(attachment.Name, ImageData); 


        }
