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：

<%@ 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 id='current" + counter + "'><img height='65px' width='65px' src='" + uploadedfile + "' alt='" + uploadedfile + "'/><div id='close" + counter + "' 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> <td> <a id="addImage" href="javascript:;">Add Image</a> </td> </tr> <tr> <td valign="top"> <div id="uploadImageWrapper"> </div> </td> </tr> <tr> <td> <div id="loading"> <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"> </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。
