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); }
