Upload image to server using C#/.NET and storing filename in DB

Question

I\'m currently using the following snippet to insert data into a table in my database. It works great. But, I want to start adding filename data and not sure how to proceed.

Answer 1

To store the file in an images folder, it should be:

FileUpload1.SaveAs(Server.MapPath("~/Images/" + FileUpload1.FileName));

and then add the command parameters in the fileName

comm.Parameters["@FileName"].Value = FileUpload1.FileName;

Note: you must have the FileName field in your DB table.

Answer 2

I suggest storing file in the db too. This will guarantee data consistency.

Add column to the DB. Replace X with the suitable size if the image is less than 8000, or specify varbinary(MAX) if it is not.

alter table Entries
    add FileContent varbinary(X) not null

C# code:

byte[] fileContent = yourFileContent;
using(var connection = new SqlConnection(connectionString))
using (var command = connection.CreateCommand())
{
    command.CommandText = @"
        INSERT INTO Entries (Title, Description, FileContent)
        VALUES (@Title, @Description, @FileContent)
        ";
    command.Parameters.AddWithValue("Description", descriptionTextBox.Text);
    command.Parameters.AddWithValue("Title", titleTextBox.Text);
    command.Parameters.AddWithValue("FileContent", fileContent);
    connection.Open();
    command.ExecuteScalar();
}
