多文件上传

第一种方法

 

 //上传文件

        public void FN_UpFiles()

        {

            //遍历File表单元素

            HttpFileCollection files = HttpContext.Current.Request.Files;

            //StringBuilder strMsg = new StringBuilder();

            //strMsg.Append("上传的文件分别是：<hr color='pink'/>");

            try

            {

                for (int iFile = 0 ; iFile < files.Count ; iFile++)

                {

                    //检查文件扩展名字

                    HttpPostedFile postedFile = files[iFile];

                    string fileName = "";

                    //string fileExtension = "";

                    fileName = Path.GetFileName(postedFile.FileName);

                    if (fileName != "")

                    {

                        try

                        {

                            string strpath = HttpContext.Current.Request.MapPath("~/ResourcesFolder/") + fileName;

                            if (System.IO.File.Exists(strpath))

                            {

                                Response.Write("已经存在文件：" + fileName + "<br>");

                            }

                            else

                                    Guid guid3 = Guid.NewGuid();

                                    Guid guid4 = Guid.NewGuid();

                                    model.Fileid = guid1;

                                    model.Folderid = guid2;

                                    model.Filepath = strpath;

                                    model.FileNam = fileName.ToString();

                                    model.ModefyBy = guid4;

                                    if (bf.FN_AddNewRes(model) > 0)

                                    {

                                        //fileExtension = Path.GetExtension(fileName);

                                        //strMsg.Append("上传的文件类型：" + postedFile.ContentType.ToString() + "<br>");

                                        //strMsg.Append("客户端文件地址：" + postedFile.FileName + "<br>");

                                        //strMsg.Append("上传文件的文件名：" + fileName + "<br>");

                                        //strMsg.Append("上传文件的大小：" + postedFile.ContentLength.ToString() + "个字节" + "<br>");

                                        postedFile.SaveAs(System.Web.HttpContext.Current.Request.MapPath("~/ResourcesFolder/") + fileName);

                                        Page.RegisterStartupScript("提示", "<script language='javascript'>alert('上传成功!')</script>");

                                        Response.Write("<script language='javascript'>self.opener.location.reload();</script>");

                                        Response.Write("<script language='javascript'>window.close();</script>");

                                    }

                                }

                                catch (Exception ex)

                                {

 

                                    Response.Write(ex.ToString());

                                }

 

                            }

 

                        }

                        catch (Exception ex)

                        {

                            Response.Write(ex.ToString());

                        }

                    }

                    else

                    {

                        Page.RegisterStartupScript("提示", "<script language='javascript'>alert('没有添加上传文件！')</script>");

                    }

                }

            }

            catch (System.Exception ex)

            {

                Response.Write(ex.ToString());

            }

 

第二种方法

 

public partial class _Default : System.Web.UI.Page  

{ 

    protected void Page_Load(object sender, EventArgs e) 

    { 

 

    } 

    protected void bt_upload_Click(object sender, EventArgs e) 

    { 

        if (FileUpload1.PostedFile.FileName == "" && FileUpload2.PostedFile.FileName == "" && FileUpload3.PostedFile.FileName == "") 

        { 

            this.lb_info.Text = "请选择文件！"; 

        } 

        else 

        { 

            HttpFileCollection myfiles = Request.Files; 

            for (int i = 0; i < myfiles.Count; i++) 

            { 

                HttpPostedFile mypost = myfiles[i]; 

                try 

                { 

                    if (mypost.ContentLength > 0) 

                    { 

                        string filepath = mypost.FileName;//C:\Documents and Settings\Administrator\My Documents\My Pictures\20022775_m.jpg 

                        string filename = filepath.Substring(filepath.LastIndexOf("\\") + 1);//20022775_m.jpg 

                        string serverpath = Server.MapPath("~/images/") + filename;//C:\Inetpub\wwwroot\WebSite2\images\20022775_m.jpg 

                        mypost.SaveAs(serverpath); 

                        this.lb_info.Text = "上传成功！"; 

                    } 

                } 

                catch (Exception ex)
