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：
复制代码 代码如下:
create table image1
(
ID int identity(1,1) primary key,
ImageName varchar(100) ,
ImageType varchar(20),
ImagePath varchar(200)
)
代码：
复制代码 代码如下:
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td colspan="2" style="height: 21px">
</td>
</tr>
<tr>
<td style="width: 400px">
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Label ID="label1" runat="server" ForeColor="Red"></asp:Label>
</td>
<td style="width: 80px">
<asp:Button ID="UploadButton" runat="server" Text="上传图片" OnClick="UploadButton_Click" />
</td>
</tr>
<tr>
<td colspan="2" align="center">
<br />
<br />
<asp:Image ID="Image1" runat="server" Height="118px" Width="131px" />
</td>
</tr>
</table>
</div>
</form>
</body>
