Question

i have uploaded a file to folder named quiz and save it using

    server_filepath = Server.MapPath(folderName) + "\\" + fileName;
        fileUpload.PostedFile.SaveAs(server_filepath);
cmd.CommandText = "Insert Into quiz(description) Values('" + server_filepath +  "')";

and save the link of uploaded file to database.

that link is displayed in another page as.

<asp:BulletedList ID="BulletedList1" runat="server" DisplayMode="HyperLink" 
            DataSourceID="SqlDataSource1" DataTextField="description" 
            DataValueField="id">
        </asp:BulletedList>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:chaaapaConnectionString4 %>" 
            SelectCommand="SELECT * FROM [quiz]"></asp:SqlDataSource>

but when click on the link the error occurs
that is the resource cannot be found.

Answer 1

You’re saving an absolute path (C:\inetpub\wwwroot\yoursite\quiz\filename.pdf) to the database.

Try saving Path.Combine(folderName, fileName) to the database, and use that as the hyperlink instead.
