OleDbCommand Cmd = new OleDbCommand（）; OleDbDataAdapter myAdapter = new OleDbDataAdapter（）; Cmd.CommandText =“选择CCont，来自SaveImage的图像，其中CCont ='”+ textBoxet.Text +“'”; Cmd.Connection = myConn;

        myAdapter.SelectCommand = Cmd;

        try
        {
            myConn.Open();
            myAdapter.Fill(ds.Tables[0]);
            myConn.Close();
        }
        catch (Exception ex)
        {
            throw;
        }


        for (int index = 0; index < ds.Tables[0].Rows.Count; index++)
        {
            if (ds.Tables[0].Rows[index]["image"].ToString() != "")
            {
                string s = ds.Tables[0].Rows[index]["image"].ToString();

                if (File.Exists(s))
                {
                    LoadImage(ds.Tables[0].Rows[index], "image", s);
                }
                else
                {
                    LoadImage(ds.Tables[0].Rows[index], "image",
                              "DefaultPicturePath");
                }
            }
            else
            {
                LoadImage(ds.Tables[0].Rows[index], "image",
                          "DefaultPicturePath");
            }
        }

        try
        {
            // Finally display report in crystal report viewer
            ReportDocument crDoc = new ReportDocument();
            crDoc.Load("CrystalReport1.rpt");
            crDoc.SetDataSource(ds.Tables[0]);

}
