C#文件上傳及查看，C#文件上傳到數據庫

心動一下：

web:  ascx頁面

<tr>
<td>
<asp:Label ID="Label7" runat="server" Text="上傳文件:"></asp:Label>
</td>
<td>
<asp:FileUpload ID="FileInfo" runat="server" />
</td>
<td>
<asp:Label ID="lblFileDescription" runat="server" Text="文件備注或說明:"></asp:Label>
</td>
<td>
<asp:TextBox ID="tbxFileRemarks" runat="server" Width="254px"></asp:TextBox>
<asp:Button ID="btnUploadFile" runat="server" OnClick="btnUploadFile_Click" Text="上傳" />
<asp:Label ID="filemessage" runat="server"></asp:Label>
</td>
</tr>
