[已解决]在保存附件功能中，它是否将对象引用设置为未设置为对象的实例？

问题描述

protected void SaveAttachments(Int32 actRuleID)
    {
        if (gvAttachments.Rows.Count > 0)
        {
            if ((Session["FileDetail"].ToString() != ""))
            {
                string[] Records = Session["FileDetail"].ToString().Split('#');
                byte[] fileContent;
                FileStream fs;
                BinaryReader br;
                for (int i = 0; i < Records.Length; i++)
                {

                    string[] arrRecords = Records[i].Split(',');

                    fs = new FileStream(arrRecords[2], FileMode.Open, FileAccess.Read);
                    br = new BinaryReader(fs);
                    fileContent = br.ReadBytes((int)fs.Length);
                    br.Close();
                    fs.Close();
                    Econnect.EEMS.ActRulesAttachments objAttachment = new Econnect.EEMS.ActRulesAttachments();
                    objAttachment.ActRuleID = actRuleID;
                    objAttachment.FileName = arrRecords[0].ToString();
                    objAttachment.FileFormat = arrRecords[3].ToString();
                    objAttachment.FileContent = fileContent;
                    context.ActRuleAttachments.Add(objAttachment);
                    context.SaveChanges();
                }
            }

        }
    }
