C#实现上传照片到物理路径,并且将地址保存到数据库的小例子
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:
create table image1 ( ID int identity(1,1) primary key, ImageName varchar(100) , ImageType varchar(20), ImagePath varchar(200) )
代码:
<body> <form id="form1" runat="server"> <p> <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> </p> </form> </body>
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.IO; using System.Configuration; using System.Data; using System.Data.SqlClient; namespace InExcelOutExcel { public partial class UpWord : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } string SQLString = ConfigurationManager.ConnectionStrings["ConnectionStr"].ToString(); protected void UploadButton_Click(object sender, EventArgs e) { try { using (SqlConnection sqlcon = new SqlConnection(SQLString)) { string FullName = FileUpload1.PostedFile.FileName;//获取图片物理地址 FileInfo fi = new FileInfo(FullName); string name = fi.Name;//获取图片名称 string type = fi.Extension;//获取图片类型 if (type == ".jpg" || type == ".gif" || type == ".bmp" || type == ".png") { string SavePath = Server.MapPath("~\\excel");//图片保存到文件夹下 this.FileUpload1.PostedFile.SaveAs(SavePath + "\\" + name);//保存路径 this.Image1.Visible = true; this.Image1.ImageUrl = "~\\excel" + "\\" + name;//界面显示图片 string sql = "insert into image1(ImageName,ImageType,ImagePath) values('" + name + "','" + type + "','~\\excel" + name + "')"; SqlCommand cmd = new SqlCommand(sql, sqlcon); sqlcon.Open(); cmd.ExecuteNonQuery(); this.label1.Text = "上传成功"; } else { this.label1.Text = "请选择正确的格式图片"; } } } catch (Exception ex) { Response.Write(ex.Message); } } } }
