C# save PDF file in DB
Apr 27 2020 4:30 PM
Hi everyone,
i'm trying to save PDF file into SQL DB.
I don't get any error, but PDF is not saved in data table.
Here is my code:
//select PDF, open/show file and show location in textbox
public
void
button1_Click(
object
sender, EventArgs e)
{
OpenFileDialog openfd =
new
OpenFileDialog();
openfd.Filter =
"PDF Files (*.pdf)|*.pdf"
;
if
(openfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
axAcroPDF1.src = openfd.FileName;
textBox1.Text = openfd.FileName;
}
else
{ }
}
//save/upload button
private
void
button2_Click(
object
sender, EventArgs e)
{
if
(textBox1.Text !=
null
)
try
{
byte
[] pdfb =
null
;
FileStream fs =
new
FileStream(textBox1.Text, FileMode.Open, FileAccess.Read);
BinaryReader br =
new
BinaryReader(fs);
pdfb = br.ReadBytes((
int
)fs.Length);
SqlConnection cn =
new
SqlConnection(@
"Data Source=MAIN-PC\SQLEXPRESS;Database = "
+ comboBox1.Text +
";Integrated Security=True"
);
string
query =
"Insert into tblInvoices (StoreCode,Supplier,RID,Status)values ('"
+ comboBox2.Text +
"','"
+ comboBox3.Text +
"','"
+ DateTime.Now.ToString()+
"', 'Received')"
;
SqlCommand command =
new
SqlCommand(query, cn);
command.Parameters.Add(
"@InvoicePDF"
, SqlDbType.VarBinary, 8000).Value = pdfb;
cn.Open();
command.ExecuteNonQuery();
cn.Close();
MessageBox.Show(
"Invoice uploaded successfully"
, MessageBoxIcon.Information.ToString(), MessageBoxButtons.OK );
}
catch
(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
SQL DB,Table config is:
StoreCode varchar(50) Checked
Supplier nvarchar(50) Unchecked
RID date Unchecked
CID date Checked
Status nvarchar(50) Unchecked
InvoicePDF varbinary(MAX) Checked
Managed nvarchar(50) Checked
Unchecked
