Question

protected void ADMIN_FILEUPLOAD_BT_Click(object sender, EventArgs e)
    {
            String savePath = "C:\\Documents and Settings\\Dang\\My Documents\\Visual Studio 2008\\WebSites\\新闻发布系统\\Upload\\";
            bool boolean = false;
            string FileName="a";
            string FilePath="b";
            if (ADMIN_FileUpload1.HasFile)
            {
                String fileName = ADMIN_FileUpload1.FileName;
                savePath += fileName;
                ADMIN_FileUpload1.SaveAs(savePath);
                FileName = fileName;
                FilePath = savePath;
                boolean = true;
            }
            else
            {
               Response.Write("<script language=javascript>alert('您没有选择一个文件进行上传！')</script>");
            }
            if (boolean) {
              DBAccess DB = new DBAccess();
                string strSql = " INSERT INTO Download  (filepath, filename) VALUES ('"+FilePath+"', '"+FileName+"')";
                DB.DealData(strSql);
                Response.Write("<script language=javascript>alert('上传成功！')</script>");
            }
        }以上是我写的代码 可是 怎么也无法获取字符串 修改不了数据库
请大家帮忙解决一下

Answer 1

是不是没有权限上传到C:\\Documents and Settings\\Dang\\My Documents\\Visual Studio 2008\\WebSites\\新闻发布系统\\Upload\\

Answer 2

上传已经成功 只是无法获取FilePath 还有FileName两个字符串 
我是想把这些路径放到一个数据库中 然后在下载的时候直接通过数据库生成下载的文件的列表

Answer 3

LZ自己输出下FilePath 还有FileName看看是不是你想要的数据
 if (FileUpload1.PostedFile.FileName != "")
        {
            try
            {
                string FlvPath = FileUpload1.PostedFile.FileName;
                string FlvName = FlvPath.Substring(FlvPath.LastIndexOf("\\") + 1);
                string FlvExtend = FlvPath.Substring(FlvPath.LastIndexOf(".") + 1);
                if (!(FlvExtend == "flv"))
                {
                    message.Text = "上传图片的格式不正确！";
                    return;
                }
                string ServerPath = Server.MapPath("flv/") + FlvName;
                FileUpload1.PostedFile.SaveAs(ServerPath);
                SqlConnection con = new SqlConnection(WebConfigurationManager.ConnectionStrings["testConnectionString1"].ConnectionString);
                con.Open();
                SqlCommand com = new SqlCommand("insert into Video(VideoPath)values('" + FlvName + "')", con);
                com.ExecuteNonQuery();
                con.Close();
                message.Text = "上传成功，图片名称为：" + FlvName;
            }
            catch (Exception se)
            {
                message.Text = se.ToString();
            }
        }

Answer 4

这是一个上传图片的例子
看看管不管用public void add()
    {
        //获取图片的基目录
        string path = AppDomain.CurrentDomain.BaseDirectory;
        //获得上传图片的名称
        string imgname = imgUp.FileName.ToString();
        string strFileName = this.imgUp.PostedFile.FileName;
        string strfileType = strFileName.Substring(strFileName.LastIndexOf('.') + 1).ToLower();        if (imgUp.HasFile)
        {
            if (imgUp.PostedFile.ContentType.ToLower() == "image/gif" || imgUp.PostedFile.ContentType.ToLower() == "image/pjpeg" || imgUp.PostedFile.ContentType.ToLower() == "image/bmp")
            {
                string newFielName = DateTime.Now.Ticks.ToString() + "." + strfileType;
                string strPath = Server.MapPath("/") + "ServerCenter\\admin\\Upload\\" + newFielName;
                //调用缩略图构造方法
                ImageClass imageClass = new ImageClass(imgUp.PostedFile.InputStream);
                //调用缩略图方法
                Boolean flag = imageClass.GetReducedImage(120, 110, strPath);                if (flag == true)
                {
                    string newImgFiel = DateTime.Now.Ticks.ToString() + "" + DateTime.Now.Ticks.ToString() + "." + strfileType;
                    string strNewPath = Server.MapPath("/") + "ServerCenter\\admin\\Upload\\";
                    //保存原始图片到指定路径
                    this.imgUp.SaveAs(strNewPath + newImgFiel);
                    //调用缩略图构造方法（大图片）
                    ImageClass NewImageClass = new ImageClass(imgUp.PostedFile.InputStream);                    string sql = "insert into SJ_LP values(@lp_mc,@lp_sl,@lp_tpdz,@lp_sjjz,@lp_jdjg,@lp_yhjg,@lp_ystp,@lp_bz)";
                    SqlCommand cmd = new SqlCommand(sql, conn);
                    cmd.Parameters.AddWithValue("@lp_mc", TextBox1.Text.Trim());
                    cmd.Parameters.AddWithValue("@lp_sl", TextBox2.Text.Trim());
                    cmd.Parameters.AddWithValue("@lp_tpdz", @"admin\Upload\" + imgname);
                    cmd.Parameters.AddWithValue("@lp_ystp", @"admin\Upload\" + newImgFiel);
                    cmd.Parameters.AddWithValue("@lp_sjjz", double.Parse(TextBox4.Text.Trim()));
                    cmd.Parameters.AddWithValue("@lp_jdjg", TextBox5.Text.Trim());
                    cmd.Parameters.AddWithValue("@lp_yhjg", TextBox6.Text.Trim());
                    cmd.Parameters.AddWithValue("@lp_bz", Server.HtmlEncode(WebEditor1.Text));
                    conn.Open();                    if (cmd.ExecuteNonQuery() > 0)
                    {
                        conn.Close();
                        Response.Write("<script>alert('添加成功！');</script>");
                        showgift();
                    }
                    else
                    {
                        Response.Write("<script>alert('添加失败！');</script>");
                    }
                }
                else
                {
                    Response.Write("<script>alert('添加失败！');</script>");
                }
            }
            else
            {
                Response.Write("<script>alert('服务器只允许上传gif、jpg、bmp格式的图片');</script>");
            }
        }
        else
        {
            Response.Write("<script>alert('请选择图片');</script>");
        }
    }

Answer 5

或者是private void btnbuildurl_Click(object sender, EventArgs e)
        {
            FolderBrowserDialog f = new FolderBrowserDialog();
            if (f.ShowDialog() == DialogResult.OK)
            {
                txtbuildurl.Text = f.SelectedPath;
            }
        }

Answer 6

  if (ADMIN_FileUpload1.HasFile) 
            { 
                String fileName = ADMIN_FileUpload1.FileName; 
                savePath += fileName; 
                ADMIN_FileUpload1.SaveAs(savePath); 
                FileName = fileName; 
                FilePath = savePath; 
                boolean = true; 
 if (boolean) { 
              DBAccess DB = new DBAccess(); 
                string strSql = " INSERT INTO Download  (filepath, filename) VALUES ('"+FilePath+"', '"+FileName+"')"; 
                DB.DealData(strSql); 
                Response.Write(" <script language=javascript>alert('上传成功！') </script>"); 
            }             } 
            else 
            { 
              Response.Write(" <script language=javascript>alert('您没有选择一个文件进行上传！') </script>"); 
            } 
           

Answer 7

 string Savepath = Server.MapPath("../../../UpFile/StaPhoto/");//目标存放路径,写相对路径
 string fileName = FileUpload1.FileName;

Answer 8

我重说一下问题 上传功能是完全正确的 并且可以用的
只是 无法获取FileName 和FilePath两个字符串 我单个用Label.text尝试过 显示的是正确的 但是就是如上传参数的时候无法正确给Sql语句
我想问问是不是长传过程造成页面重新启动 使得参数丧失了？
