asp.net读取磁盘文件、删除实例代码


            复制代码 代码如下:    protected void ReadFile()     //读取文件夹，文件     {         string savePath = @"common";         StringBuilder outstring = new StringBuilder();         string absSavePath = Server.MapPath(savePath);         string[] Directorys = Directory.GetDirectories(absSavePath + @"/" + Page.User.Identity.Name);         //for (int i = 0; i < Directorys.Length; i++)         //{         //    Response.Write(Directorys[i] + " <br/ >");         //}         //Response.Write("Directorys count：" + Directorys.Length + "个  <br/ >--------- <br >");         string[] Files = Directory.GetFiles(absSavePath + @"" + Page.User.Identity.Name, "*");         outstring.Append("<ul>");         for (int i = 0; i < Files.Length; i++)         {             if (Path.GetFileName(Files[i]) != "Thumbs.db")             {                 outstring.Append("<li><img src=/"common/" + Path.GetFileName(Files[i]) + "/" style=/"width:100px;height:100px;/" /><br/><input type=/"checkbox/" value=/"common/" + Path.GetFileName(Files[i]) + "/" name=/"picname/" onclick=/"getpicid();/" id=/"imgid" + i.ToString() + "/" /><label for=/"imgid" + i.ToString() + "/">" + Path.GetFileName(Files[i]) + "</label></li>");             }         }         outstring.Append("</ul>");         Response.Write(outstring.ToString());     } 

//删除文件         string[] strpicname = Request["imgids"].Split(new char[] { ',' });         for (int i = 0; i < strpicname.Length; i++)         {             File.Delete(Server.MapPath(strpicname[i].ToString()));         } 复制代码 代码如下://循环遍历复选框 <script language="javascript" type="text/javascript" defer="defer">     var imgnum = document.getElementsByTagName("input");     var imgids = "";     function getpicid()     {         document.getElementById("hidimgid").value = "";         for (var i=0;i<imgnum.length;i++)         {             if ( imgnum[i].type == "checkbox" && imgnum[i].name == "picname" && imgnum[i].checked)             {                 imgids += imgids == "" ? imgnum[i].value : "," + imgnum[i].value;             }         }         document.getElementById("hidimgid").value = imgids;     }     </script>
