点滴积累【C#】---C#实现上传照片到物理路径，并且将地址保存到数据库，

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                     &nbsp;
 8                 </td>
 9             </tr>
10             <tr>
11                 <td style=" 400px">
12                     <asp:FileUpload ID="FileUpload1" runat="server" />
13                     &nbsp;<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>
