C#图片上传效果实例分析

本文实例讲述了C#图片上传效果实现方法。分享给大家供大家参考。具体如下:@H_403_1@<%@ Page Title=”” Language=”C#” MasterPageFile=”~/Default.master” AutoEventWireup=”true” CodeFile=”Default.aspx.cs” Inherits=”Default” %><asp:Content ID=”cHead” ContentPlaceHolderID=”head” runat=”Server”></asp:Content><asp:Content ID=”cBody” ContentPlaceHolderID=”ContentPlaceHolder1″ runat=”Server”><asp:Literal runat=”server” ID=”ltrHTML”></asp:Literal><script type=”text/javascript”> $().ready(function () { var counter = 0; $(function () { var btnUpload = $(‘#addImage’); new AjaxUpload(btnUpload,{ action: ‘saveupload.aspx’,name: ‘uploadfile’,onSubmit: function (file,ext) { $(“#loading”).show(); },onComplete: function (file,response) { var uploadedfile = “UserData/” + file; $(“#uploadImageWrapper”).append(“<div class=’imageContainer offset’ id=’current” + counter + “‘><img height=’65px’ width=’65px’ src='” + uploadedfile + “‘ alt='” + uploadedfile + “‘/><div id=’close” + counter + “‘ class=’close’ title='” + uploadedfile + “‘ onclick=’RemoveImage(this);’><a ></a></div></div>”); $(‘#current’ + counter).fadeIn(‘slow’,function () { $(“#loading”).hide(); $(“#message”).show(); $(“#message”).html(“Added successfully!”); $(“#message”).fadeOut(3000); counter++; }); } }); }); }); function RemoveImage(_this) { var counter = _this.id.replace(‘close’,”); $(“#loading”).show(); $.ajax({ type: “POST”,url: “removeupload.aspx”,data: “filename=” + _this.getAttribute(‘title’),success: function (msg) { $(‘#current’ + counter).fadeOut(‘slow’,function () { $(“#loading”).hide(); $(“#message”).show(); $(“#message”).html(“Removed successfully!”); $(“#message”).fadeOut(3000); }); } }); } </script> <table id=”imageUploader” cellpadding=”0″ cellspacing=”0″> <tr class=”header”> <td style=”padding-left: 5px;”> <a id=”addImage” href=”javascript:;”>Add Image</a> </td> </tr> <tr class=”body”> <td valign=”top”> <div id=”uploadImageWrapper”> </div> </td> </tr> <tr class=”footer”> <td> <div id=”loading” style=”display: none”> <table cellpadding=”0″ cellspacing=”0″> <tr> <td> <img width=”20″ height=”20″ src=”Images/Loading.gif” alt=”Loading…” /> </td> <td> Please wait… </td> </tr> </table> </div> <div id=”message” style=”color: Green”> </div> </td> </tr> </table> </asp:Content>

希望本文所述对大家的C#程序设计有所帮助。@H_403_1@
