using System.Web;
namespace Hot

/// UploadHandler 的摘要说明
/// </summary>
public class UploadHandler : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
//接收上传后的文件
HttpPostedFile file = context.Request.Files["Filedata"];
//其他参数
//string somekey = context.Request["someKey"];
//string other = context.Request["someOtherKey"];
//获取文件的保存路径 创建uploads文件夹
string uploadPath =HttpContext.Current.Server.MapPath("uploads" + "\\");
//判断上传的文件是否为空
if (file != null)
{
if (!Directory.Exists(uploadPath))
{
Directory.CreateDirectory(uploadPath);
}
//1.利用InputStream 属性直接从HttpPostedFile对象读取文本内容
System.IO.Stream MyStream;
int FileLen;
FileLen = file.ContentLength;
// 读取文件的 byte[]
byte[] bytes = new byte[FileLen];
MyStream = file.InputStream;
MyStream.Read(bytes, 0, FileLen);
//2.保存到文件
file.SaveAs(uploadPath + file.FileName);
context.Response.Write("1");
}
else
{
context.Response.Write("0");
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
1.记得创建uploads文件夹，放上传的文件。
2.$('#' + file.id).find('.data').html(' 上传完毕'); 是设置显示为中文完成，不然是英文，也可以更改jquery.uploadify.js文件里的英文字。
