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。
