C＃打开一个特定的PDF页面，从SQL获取数据

Question

In my project I want to open a specific pdf page. I found a code from stackoverflow which works great here is the code

private void button1_Click(object sender, EventArgs e)
{
    startInfo.FileName = @"C:\Program Files (x86)\Foxit Software\Foxit Reader\FoxitReader.exe";
    startInfo.Arguments = "/A \"page=3\" \"C:\\Users\\test.pdf";
    Process.Start(startInfo);
} 

Yet this code is working perfectly in c# when i want to get startInfo.Arguments's data from sql it only opens the last page which I opened with button1_Click .

This is how im trying to get data with sql;

SqlCommand sqlCmd = new SqlCommand("Select * From table ", baglanti);
baglanti.Open();
SqlDataReader reader = sqlCmd.ExecuteReader();
try
{
    while (reader.Read())
    {
        if (reader[1].ToString() == "pdf")
        {
            startInfo.FileName = @reader[4].ToString();
            startInfo.Arguments = reader[3].ToString();
            Process.Start(startInfo);
        }           
    }

    baglanti.Close();
    reader.Close();
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message.ToString());
}

Another thing is after I open a specific pdf page something like page 15 with button and then I want to open pdf from windows normally it also opens from page 15. Its like I cant dispose the argument after I use it.

So is anyone know anything about this issue or can see where I am wrong?

Answer 1

Your code works fine when I use it in a test application. What I noticed now from your comments is that you have a space in the arguments between / and A . Remove it and make sure your path to the PDF is correct (no double escape sequences in your database row or something similar). So your output should be the following to get it running properly:

reader[1]: "pdf"
reader[3]:  "/A \"page=1\" \"C:\\Users\\dzcgkv\\Desktop\\Kiosk\\EOP-HPV_006_DHPV_HİDROLİK_MONTAJ.pdf\""
reader[4]: "C:\\Program Files (x86)\\Foxit Software\\Foxit Reader\\FoxitReader.exe"
