XhEditor上传

首先导入js文件：

  <script type="text/javascript" src="../xheditor/jquery/jquery-1.4.4.min.js"></script>
    <script type="text/javascript" src="../xheditor/xheditor-1.1.10-zh-cn.min.js"></script>
    <script type="text/javascript">
        $(function () {
            $('#txt_content').xheditor({ cleanPaste: 0, tools: 'mfull', skin: 'nostyle', upLinkUrl: '../upload.aspx', upImgUrl: '../upload.aspx', upFlashUrl: '../upload.aspx', upMediaUrl: '../upload.aspx' });
        })
    </script>

新建一个upload.aspx文件（后台代码如下）：

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Text.RegularExpressions;
public partial class upload : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        //初始化一大堆变量
        string inputname = "filedata";    //表单文件域name
        string attachdir = "uploads";     // 上传文件保存路径，结尾不要带/
        int dirtype = 1;                  // 1:按天存入目录 2:按月存入目录 3:按扩展名存目录  建议使用按天存
        int maxattachsize = 419430400;     // 最大上传大小，默认是2M
        string upext = "txt,rar,zip,JPG,GIF,jpg,jpeg,bmp,gif,png,swf,wmv,avi,wma,mp3,mid,flv";    // 上传扩展名
        int msgtype = 2;                 //返回上传参数的格式：1，只返回url，2，返回参数数组
        string immediate = Request.QueryString["immediate"];//立即上传模式，仅为演示用
        byte[] file;                     // 统一转换为byte数组处理
        string localname = "";
        string disposition = Request.ServerVariables["HTTP_CONTENT_DISPOSITION"];

        string err = "";
        string msg = "''";

        if (disposition != null)
        {
            // HTML5上传
            file = Request.BinaryRead(Request.TotalBytes);
            localname = Regex.Match(disposition, "filename=\"(.+?)\"").Groups[1].Value;// 读取原始文件名
        }
        else
        {
            HttpFileCollection filecollection = Request.Files;
            HttpPostedFile postedfile = filecollection.Get(inputname);

            // 读取原始文件名
            localname = postedfile.FileName;
            // 初始化byte长度.
            file = new Byte[postedfile.ContentLength];

            // 转换为byte类型
            System.IO.Stream stream = postedfile.InputStream;
            stream.Read(file, 0, postedfile.ContentLength);
            stream.Close();

            filecollection = null;
        }

        if (file.Length == 0) err = "无数据提交";
        else
        {
            if (file.Length > maxattachsize) err = "文件大小超过" + maxattachsize + "字节";
            else
            {
                string attach_dir, attach_subdir, filename, extension, target;

                // 取上载文件后缀名
                extension = GetFileExt(localname);

                if (("," + upext + ",").IndexOf("," + extension + ",") < 0) err = "上传文件扩展名必需为：" + upext;
                else
                {
                    switch (dirtype)
                    {
                        case 2:
                            attach_subdir = "month_" + DateTime.Now.ToString("yyMM");
                            break;

                    // 生成随机文件名
                    Random random = new Random(DateTime.Now.Millisecond);
                    filename = DateTime.Now.ToString("yyyyMMddhhmmss") + random.Next(10000) + "." + extension;

                    target = "/" + attach_dir + filename;
                    try
                    {
                        CreateFolder(Server.MapPath(attach_dir));

                        System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath(target), System.IO.FileMode.Create, System.IO.FileAccess.Write);

    public void CreateFolder(string FolderPath)

　　新建一个uploads文件夹即可
