我需要上傳在網站中選擇的圖像到數據庫我的項目有多個文件選擇「文件上傳」如何將多個文件上傳到數據庫二進制格式的圖像數據,我的代碼是如何將選定的多個圖像上傳到數據庫
protected void Button1_Click(object sender, EventArgs e)
{
string Qry = "insert into tblFiles values(@data)";
SqlConnection con = new SqlConnection(@"Data Source=ESLHPC17\SQL2008;Initial Catalog=dbFiles;User ID=user;Password=password");
SqlCommand cmd = new SqlCommand(Qry,con);
cmd.Parameters.Add("@data") = FileUpload1.FileBytes;
}
我使用下面的Web處理程序保存文件在本地文件夾
<%@ WebHandler Language="C#" Class="Upload" %>
using System;
using System.Web;
using System.IO;
public class Upload : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
context.Response.Expires = -1;
try
{
HttpPostedFile postedFile = context.Request.Files["Filedata"];
string savepath = "";
string tempPath = "";
tempPath = System.Configuration.ConfigurationManager.AppSettings["FolderPath"];
savepath = context.Server.MapPath(tempPath);
string filename = postedFile.FileName;
if (!Directory.Exists(savepath))
Directory.CreateDirectory(savepath);
postedFile.SaveAs(savepath + @"\" + filename);
context.Response.Write(tempPath + "/" + filename);
context.Response.StatusCode = 200;
}
catch (Exception ex)
{
context.Response.Write("Error: " + ex.Message);
}
}
public bool IsReusable {
get {
return false;
}
}
}
我用的是下面得離譜PT
<script type = "text/javascript">
$(window).load(
function() {
$("#<%=FileUpload1.ClientID%>").fileUpload({
'uploader': 'scripts/uploader.swf',
'cancelImg': 'images/cancel.png',
'buttonText': 'Browse Files',
'script': 'Upload.ashx',
'folder': 'Uploads',
'fileDesc': 'Image Files',
'fileExt': '*.jpg;*.jpeg;*.gif;*.png',
'multi': true,
'auto': false
});
,但我想將圖像存儲在數據庫
@ Damith
我有以下提到的代碼,但它沒有工作試過,
protected void Button1_Click(object sender, EventArgs e)
{
string [email protected]"E:\Rajesh_Kumar\Application\Valuation\ExamManagement\ExamManagement\Uploads";
string path = System.Configuration.ConfigurationManager.AppSettings[FolderPath];
string Qry = "insert into tblFiles values(@data) Values (data)";
SqlConnection con = new SqlConnection(@"Data Source=ESLHPC17\SQL2008;Initial Catalog=dbFiles;User ID=rajesh";
StreamReader sr = new StreamReader(path);
while (sr.ReadLine() != null)
{
using (SqlCommand cmd = new SqlCommand(Qry, con))
{
cmd.Parameters.Add("@data",SqlDbType.VarBinary).Value = path;
con.Open();
cmd.ExecuteNonQuery();
}
con.Close();
con.Dispose();
}
}
你真的不應該暴露你的'sa'密碼。您的應用程序也不應以「sa」用戶身份登錄。 – 2013-05-07 10:59:39
執行命令,你會被設置。你的問題是什麼? – CodeCaster 2013-05-07 11:07:28
@CodeCaster問題是,目前只處理單個文件 – LukeHennerley 2013-05-07 11:10:27
