 string query = "select * from gateentry2 where passno='" + strpassno_imgname + "'";
            objclsvrb.objSqladp = new SqlDataAdapter(query,objclsvrb.constring);
            DataSet1 ds1 = new DataSet1();
            objclsvrb.objSqladp.Fill(ds1, "gateentry2");
            DataTable dt = new DataTable();
            DataRow drow = null;
            //dt.Columns.Add("Image", System.Type.GetType("System.Byte[]"));

            dt.Columns.Add("Image", typeof(byte[]));
            drow = dt.NewRow();
            FileStream fs = default(FileStream);
            BinaryReader br = default(BinaryReader);
      
            if (File.Exists(Application.StartupPath + "\\Images\\" + strpassno_imgname + ".Jpg"))
            {
                fs = new FileStream(Application.StartupPath + "\\Images\\" + strpassno_imgname + ".Jpg", FileMode.Open);
            }
            else
            {
                fs = new FileStream(AppDomain.CurrentDomain.BaseDirectory + "NoPhoto.jpg", FileMode.Open);
            }

            br = new BinaryReader(fs);
            byte[] imgbyte = new byte[fs.Length + 1];
            imgbyte = br.ReadBytes(Convert.ToInt32((fs.Length)));
            drow[0] = imgbyte;
            dt.Rows.Add(drow);

            br.Close();

            fs.Close();
            CrystalReport1 rptobj = new CrystalReport1();
            //dt = ds1.Tables[0];
            rptobj.SetDataSource(dt);
            crystalReportViewer1.ReportSource = rptobj;

推荐答案

试试看:

DataRow卓尔；

Hi, Try this:

DataRow drow;

dt.Columns.Add("Image", typeof(byte[]));

drow = dt.NewRow();

////您缺少大括号

然后使用方括号代替

// you were missing the braces

and then, use square braces instead

drow[0] = imgbyte;

如您所见，它非常简单.

As you can see, its pretty simple.
