<%@ WebHandler Language="C#" Class="UploadImage" %>
using System;
using System.Web;
public class UploadImage : IHttpHandler
{//文件上傳目錄private string uploadFolder = "UploadImage";public void ProcessRequest(HttpContext context){context.Response.ContentType = "text/plain";HttpFileCollection files = context.Request.Files;if (files.Count > 0){string path = context.Server.MapPath(uploadFolder);HttpPostedFile file = files[0];if (file != null && file.ContentLength > 0){string fileName = DateTime.Now.ToString("yyyyMMddhhmmss") + context.Request.Form["fileName"];string savePath = path + "/" + fileName;file.SaveAs(savePath);System.Web.HttpResponse obj = context.Response;obj.Write(fileName);}}else{context.Response.Write("參數錯誤");context.Response.End();}}public bool IsReusable {get {return false;}}
}
