復(fù)制代碼代碼如下:

<%@ WebHandler Language="C#" Class="UploadHandler" %>

using System;
using System.Web;
using System.IO;

public class UploadHandler : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";
        context.Response.Charset = "utf-8";

HttpPostedFile file = context.Request.Files["Filedata"];
string uploadPath = HttpContext.Current.Server.MapPath(@context.Request["folder"]);

        if (file != null)
        {
            if (!Directory.Exists(uploadPath))
            {
                Directory.CreateDirectory(uploadPath);
            }
            file.SaveAs(Path.Combine(uploadPath, file.FileName));
            context.Response.Write("1");
        }
        else
        {
            context.Response.Write("0");
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}
