关于文件上传问题，我上传的文件没有保存到指定的文件夹下面而是保存到了根目录，求解~~

Question

if (FileUpload1.HasFile)
                        {
                         
                           // this.strUploadFileDir = Server.MapPath("~/hyn/");
                            string UserDirectory = "hyn";//所要创建文件夹的名字，实际运用中可为用户注册ID
                            string UserPath = Server.MapPath("UploadFiles").ToString() + "\\" + UserDirectory + "\\";
                            if (!Directory.Exists(UserPath)) //如果文件夹不存在则创建
                            {
                                Directory.CreateDirectory(UserPath);
                            }
                            FileUpload1.SaveAs(Server.MapPath("~/") + FileUpload1.FileName);
                            label.Text = "上传成功！";
                        } else{
                                    string[] tmpStringArr = Directory.GetFiles(strUploadFileDir);
                                    if (tmpStringArr.Length > 0)
                                    {
                                        for (int i = 0; i < tmpStringArr.Length; i++)
                                        {
                                            tmpStringArr[i].Remove(0);
                                        }
                                    }

Answer 1

    string UserDirectory = "hyn";//所要创建文件夹的名字，实际运用中可为用户注册ID
                            string UserPath = Server.MapPath("UploadFiles").ToString() + "\\" + UserDirectory + "\\";
                            if (!Directory.Exists(UserPath)) //如果文件夹不存在则创建
                            {
                                Directory.CreateDirectory(UserPath);
                            }
                            FileUpload1.SaveAs(Server.MapPath("~/") + FileUpload1.FileName);
                            label.Text = "上传成功！";你前面创建文件夹 后面保存的时候地址是Server.MapPath("~/") 这个对么？？

Answer 2

    protected void pictureUpLoad_Click(object sender, EventArgs e)
    {
        //获取图片名称
        string fileName = picUpload.FileName;
        if (fileName != "")
        {
            //设置图片路径
            string path = Server.MapPath("~/images/Joins/");
            //判断文件夹是否存在 
            if (!System.IO.Directory.Exists(path))
            {
                //创建文件夹 
                System.IO.Directory.CreateDirectory(path);
            }
            else
            {
                //将图片名称都同意格式化yyyyMMddHHmmss+后缀
                String randomStr = "Img" + DateTime.Now.ToString("yyyyMMddHHmmss", DateTimeFormatInfo.InvariantInfo);
                string lastName = randomStr + System.IO.Path.GetExtension(this.picUpload.FileName); //名字+后缀               
                //保存图片
                picUpload.SaveAs(path + lastName);
                txtImage.Text = lastName;
            }
        }
        else
        {
            Response.Write("<script language=javascript>alert('不能上传空文件')</script>");
        }
    }

Answer 3

不是的，我要保存到hyn文件夹下面。

Answer 4

根据你的代码 UserPath是你hyn文件夹的目录  那你保存文件的时候直接
 FileUpload1.SaveAs(UserPath+"\\" + FileUpload1.FileName);就可以了啊
