大伟,补分啦! 还得麻烦你一件事asp.net 图片上传怎么实现?要代码!我以前是有winform实现的上传,现在想用asp.net的网页实现,谢谢! 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 FileUpload 控件 <asp:FileUpload ID="fileHeader" runat="server" />cs代码:string path = Server.MapPath("~/plmnhytf12f3"); string header = ""; if (fileHeader.FileName != "") { path = path + "/jobs/" + id + "/"; header = "/plmnhytf12f3/jobs/" + id + "/" + fileHeader.FileName; string sql = "update vogues set header='" + header + "' where id=" + id; DbHelperSQL.GetSingle(sql); Directory.CreateDirectory(path); fileHeader.SaveAs(path+fileHeader.FileName); }自己看着整呗 图片存储:通过文件上传获取图片并转换成Byte[]字节数组,保存到数据库Image字段昨晚给你整的读取,我以为你会图片存入数据库呢,下面的根据你需要进行改改,就是数据插入那块,根据你实际字段来。<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title></head><body> <form id="form1" runat="server" style="font-size: 12px;" enctype="multipart/form-data"> 备 注:<asp:TextBox ID="name" runat="server"></asp:TextBox> 上 传:<asp:FileUpload ID="FileUpload1" runat="server" /> <asp:Button ID="Button1" runat="server" OnClientClick="return checkClint()" Text="上 传" OnClick="Button1_Click" /> <script language="javascript" type="text/javascript"> function checkClint() { var getname = document.getElementById("name"); var getfile = document.getElementById("FileUpload1"); if (getname.value == "") { alert('请输入图片备注名称!'); getname.focus(); return false; } else if (getfile.value == "") { alert('请选择上传文件路径!'); getfile.focus(); return false; } else { return true; } } </script> </form></body></html>----------------------------------------------------------------------------------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.Data.SqlClient;public partial class Default2 : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { //获取数据 string getname = this.name.Text; string getfile = this.FileUpload1.PostedFile.FileName; //上传文件 string getlastpath = FileUploadCompant(this.FileUpload1); //获取上传文件流 byte[] getbyte = new byte[this.FileUpload1.PostedFile.ContentLength]; Stream filestream = this.FileUpload1.PostedFile.InputStream; //读入数据 filestream.Read(getbyte, 0, this.FileUpload1.PostedFile.ContentLength); //插入数据 #region string sql = "insert into employee(name,Content,Type,Size,LinkUrl) values(@name,@content,@type,@size,@link)"; SqlParameter[] getpars = new SqlParameter[5]; getpars[0] = new SqlParameter("@name", getname); getpars[1] = new SqlParameter("@content", getbyte);//文件内容插入This.Fileupload1.FileBytes同样可以直接转换成Byte数组不用转换 getpars[2] = new SqlParameter("@type", this.FileUpload1.PostedFile.ContentType);//保存文件类型 getpars[3] = new SqlParameter("@size", this.FileUpload1.PostedFile.ContentLength);//文件长度 getpars[4] = new SqlParameter("@link", getlastpath); int getrescount = DBUtility.SqlHelper.ExecuteNonQuery(DBUtility.SqlHelper.connString, CommandType.Text, sql, getpars); if (getrescount == 1) { //添加成功 ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "aler ", "alert( '图片记录成功添加到数据库'); ", true); } else { //添加失败 ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "aler ", "alert( '图片记录添加失败'); ", true); } #endregion } /// <summary> /// 文件上传操作-单独隔离出来方法 /// </summary> public string FileUploadCompant(FileUpload getfileupload) { string takeServerpath = string.Empty;//保存到服务器路径 try { if (string.IsNullOrEmpty(getfileupload.PostedFile.FileName)) { ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "aler ", "alert( '请选择上传文件的路径!'); ", true); getfileupload.Focus(); } else { string filepath = getfileupload.PostedFile.FileName;//获得全路径 //获得文件名 string filename = filepath.Substring(filepath.LastIndexOf("\\") + 1); //保存服务器路径 -唯一文件名 string serverpath = Server.MapPath("FileuploadDict/") + System.DateTime.Now.ToString("yyy-MM-dd-hh-mm-ss") + Session.SessionID + filename; //保存到服务器上 getfileupload.SaveAs(serverpath); //保存成功 提示信息 ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "aler ", "alert( '文件上传成功!'); ", true); takeServerpath = serverpath; } } catch (Exception se) { //抓取一场信息 并提示 ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "aler ", "alert( '文件上传失败-上传过程出现如下异常信息:" + se.Message.ToString() + "!'); ", true); } return takeServerpath; }} 求大神 跪求一个forms验证问题!! excel导入数据(删掉原有数据) 如何保持数据完整 女程序员的问题 大虾们,给个学习.NET的进阶步骤吧!
