[Solved] Uploading Multiple Files using ASP.Net FileUpload Control saves one File in Folder (Directory) in C#

i am uploading 2 files say a.pdf and b.pdf and i am clicking on update button.I can see only a.pdf into agreement folder.It does not upload b.pdf.My VS version is below 4.0,so i used below code.

During debugging.i found that it is going through the loop but both times it takes a.pdf and skipping b.pdf as i selected both.

Source code:

<tr>
    <td class="style11">
        Reply recieved date<br />
        <asp:TextBox ID="TextBox1" Width="207" class="datepicker" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" ValidationGroup="valBtoA"
            ControlToValidate="txtrecdate" runat="server" ForeColor="red" ErrorMessage="reply date!!"></asp:RequiredFieldValidator>
    </td>
    <td class="style3">
        Agreement
        <asp:RadioButton ID="RadioButton1" GroupName="agree" AutoPostBack="true" OnCheckedChanged="enablefileuploader"
            runat="server" />
        Yes
        <asp:RadioButton ID="RadioButton2" GroupName="agree" AutoPostBack="true" OnCheckedChanged="disablefileuploader"
            runat="server" />
        No&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <a id="a1" target="_blank" runat="server">
            <asp:Label ID="Label1" ForeColor="blue" runat="server"></asp:Label>
        </a>
        <br />
    </td>
</tr>
<tr>
    <asp:FileUpload ID="FileUpload2" runat="server" accept=".pdf,.PDF" AllowMultiple="true" />
    &nbsp;&nbsp;
    <asp:Label ID="Label2" runat="server" ForeColor="red"></asp:Label>
    </td>
    <td class="style12">
        Comment2<br />
        <asp:TextBox ID="TextBox2" TextMode="MultiLine" Width="207" runat="server"></asp:TextBox>
    </td>
