问候 里亚兹
string sql = "select * from ImageUpload";
SqlDataAdapter da = new SqlDataAdapter(sql, strConn);
DataSet ds = new DataSet();
da.Fill(ds, "Image");
for (int index = 0; index < ds.Tables[0].Rows.Count; index++)
{
if (ds.Tables[0].Rows[index]["thumb_path"].ToString() != "")
{
//if (File.Exists(Server.MapPath("~/129204153594EFF/Image13.jpg") +
// ds.Tables[0].Rows[index]["thumb_path"].ToString()))
if (File.Exists(Server.MapPath("~/129204153594EFF/Image13.jpg")))
{
LoadImage(ds.Tables[0].Rows[index], "image_stream",
Server.MapPath("~/129204153594EFF/Image13.jpg"));
}
}
}
// ReportDocument crReportDocument = BLL.BusinessLogicLayer.Globals.GetReportDocument("rport.rpt");
ReportDocument crReportDocument = BLL.BusinessLogicLayer.Globals.GetReportDocument("rport.rpt");
crReportDocument.SetDataSource(ds.Tables[0]);
CrystalReportViewer1.ReportSource = crReportDocument;
}
private void LoadImage(DataRow objDataRow, string strImageField, string FilePath)
{
try
{
FileStream fs = new FileStream(FilePath, System.IO.FileMode.Open,
System.IO.FileAccess.Read);
byte[] Image = new byte[fs.Length];
fs.Read(Image, 0, Convert.ToInt32(fs.Length));
fs.Close();
objDataRow[strImageField] = Image;
}
catch (Exception ex)
