這篇文章主要介紹了c#上傳圖片，并將地址保存到數(shù)據(jù)庫中的簡單實(shí)例，有需要的朋友可以參考一下

效果：

思路：

首先，獲取圖片物理地址，然后進(jìn)行判斷將圖片保存到文件夾下，再將圖片的信息保存到數(shù)據(jù)庫。

數(shù)據(jù)庫：

create table image1
(
ID int identity(1,1) primary key,
ImageName varchar(100) ,
ImageType varchar(20),
ImagePath varchar(200)
)

代碼：

復(fù)制代碼代碼如下:

<body>
    <form id="form1" runat="server">
    <div>
        <table>
            <tr>
                <td colspan="2" style="height: 21px">
                    &nbsp;
                </td>
            </tr>
            <tr>
                <td style="width: 400px">
                    <asp:FileUpload ID="FileUpload1" runat="server" />
                    &nbsp;<asp:Label ID="label1" runat="server" ForeColor="Red"></asp:Label>
                </td>
                <td style="width: 80px">
                    <asp:Button ID="UploadButton" runat="server" Text="上傳圖片" 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>
