本文实例讲述了jQuery结合C#实现上传文件的方法。分享给大家供大家参考。具体实现方法如下:
<html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1" runat="server"> <script src="jquery-1.7.1.min.js"></script> <script src="jquery.form.js"></script> <script type="text/javascript"> function upload() { $("#form1").ajaxSubmit({ success: function (str) { alert(str); }, error: function (error) { alert(error); }, url: 'handler1.ashx', /*设置post提交到的页面*/ type: "post", /*设置表单以post方法提交*/ dataType: "text" /*设置返回值类型为文本*/ }); } </script></head><body> <form id="form1" runat="server" enctype="multipart/form-data"> <input type="file" id="file" name="file" /> <asp:Button ID="Button1" runat="server" Text="上传" OnClientClick="upload();return false;" /> </form></body>
handler1.ashx代码如下:
<%@ WebHandler Language="C#" Class="handler1" %>using System;using System.Web;public class handler1 : IHttpHandler { public void ProcessRequest (HttpContext context) { context.Response.ContentType = "text/plain"; HttpPostedFile file = context.Request.Files[0]; String fileName = System.IO.Path.GetFileName(file.FileName); file.SaveAs(context.Server.MapPath("~/") + fileName); context.Response.Write("OK"); } public bool IsReusable { get { return false; } }}
希望本文所述对大家的C#程序设计有所帮助。
