STOP SHOUTING!

Using all upper case on the web is SHOUTING and considered rude.

Try:

C#

using (SqlConnection con = new SqlConnection(strConnect))
    {
    con.Open();
    using (SqlCommand cmd = new SqlCommand("SELECT myPDFData FROM myTable", con))
        {
        using (SqlDataReader reader = cmd.ExecuteReader())
            {
            while (reader.Read())
                {
                string myPDFData = (string) reader["myPDFData"];
                File.WriteAllText(@"D:\Temp\mydata.PDF", myPDFData);
                }
            }
        }
    }

STOP SHOUTING.
I will have nothing to do with you if you are going to just be rude.

private void button1_Click_1(object sender, EventArgs e)
{

string s = "";
byte[] bytes = Convert.FromBase64String(s);

System.IO.FileStream stream =
new FileStream(@"D:\file.pdf", FileMode.CreateNew);
System.IO.BinaryWriter writer =
new BinaryWriter(stream);
writer.Write(bytes, 0, bytes.Length);
writer.Close();
}
