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 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">
