Word保存到数据以及读取的问题

保存操作

        Stream imgDataStream = this.fileLoad.PostedFile.InputStream;

        int imgDataLenth = this.fileLoad.PostedFile.ContentLength;

        byte[] imgDataList = new byte[imgDataLenth];

        imgDataStream.Read(imgDataList, 0, imgDataLenth);  

        //数据库连接语句改你的

         SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SQLCONNECTIONSTRING"].ConnectionString);

         string strSQL = "Insert into [unformatdata] (Unfordata) values(@EmployeeImage)";

         SqlCommand cmd=new SqlCommand(strSQL,conn);

         cmd.Parameters.Add("@EmployeeImage",SqlDbType.Binary);

         cmd.Parameters["@EmployeeImage"].Value = imgDataList;

         try

         {

             conn.Open();

             int retval = cmd.ExecuteNonQuery();

             MessageBox.Show("添加成功!");

         }

         catch(Exception ex)

         {

             MessageBox.Show(ex.Message);

         }

         conn.Close();

 

读取操作

        DataSet myDataSet = new DataSet();
        string updateSql = "Select   *   from   unformatdata   where   ID   = 4  ";
        //创建sqlCommand对象  
        string conString = ConfigurationManager.ConnectionStrings["SQLCONNECTIONSTRING"].ConnectionString;
        SqlConnection myConnection = new SqlConnection(conString);
        SqlCommand myCommand = new SqlCommand(updateSql, myConnection);
        myCommand.Connection.Open();
        try
        {
            SqlDataAdapter MyAdapter = new SqlDataAdapter();
            SqlCommandBuilder Var_SqlCB;
            MyAdapter.SelectCommand = myCommand;
            Var_SqlCB = new SqlCommandBuilder(MyAdapter);
           
            MyAdapter.Fill(myDataSet, "myTable");
        }
        catch (Exception ex)
        {
            System.Console.WriteLine(ex.Message.ToString());
        }

        DownloadStream(this, (byte[])myDataSet.Tables["myTable"].Rows[0]["Unfordata"],"new.doc");

 

下载的功能

        try
        {
            string MyContentType = "";
            switch (_FileName.Substring(_FileName.LastIndexOf("."), 4))
            {
                case ".xls":
                    MyContentType = "application/vnd.ms-excel";
                    break;
                case ".doc":
                    MyContentType = "application/msword";
                    break;
                default:
                    MyContentType = "application/zip";
                    break;
            }
            refPage.Response.Write("MyContentType");
            refPage.Response.Clear();
            refPage.Response.AddHeader("Content-Type", MyContentType);
            string FileName = System.Web.HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(_FileName));
            refPage.Response.AddHeader("Content-Disposition", "inline;filename=" + System.Convert.ToChar(34) + FileName +  System.Convert.ToChar(34));
            refPage.Response.AddHeader("Content-Length", FileData.Length.ToString());
            refPage.Response.BinaryWrite(FileData);
            refPage.Response.End();
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }

 

 

针对数据库字段Unfordata，如果是SQL2000最好用image类型，如果是SQL2005则可以用varbinary(max)
