效果：
思路：
首先，获取图片物理地址，然后进行判断将图片保存到文件夹下，再将图片的信息保存到数据库。
数据库：
1 create table image1 2 ( 3 ID int identity(1,1) primary key, 4 ImageName varchar(100) , 5 ImageType varchar(20), 6 ImagePath varchar(200) 7 )
代码：
1 <body> 2 <form id="form1" runat="server"> 3 <div> 4 <table> 5 <tr> 6 <td colspan="2" style="height: 21px"> 7 8 </td> 9 </tr> 10 <tr> 11 <td style=" 400px"> 12 <asp:FileUpload ID="FileUpload1" runat="server" /> 13 <asp:Label ID="label1" runat="server" ForeColor="Red"></asp:Label> 14 </td> 15 <td style=" 80px"> 16 <asp:Button ID="UploadButton" runat="server" Text="上传图片" OnClick="UploadButton_Click" /> 17 </td> 18 </tr> 19 <tr> 20 <td colspan="2" align="center"> 21 <br /> 22 <br /> 23 <asp:Image ID="Image1" runat="server" Height="118px" Width="131px" /> 24 </td> 25 </tr> 26 </table> 27 </div> 28 </form> 29 </body>
