public void ProcessRequest(HttpContext context)

}
catch (Exception ex)
{
Response.Write("Message" + ex.ToString());
}
}
}
//此方法是我自己后期会用到下载
//而上面的方法获取的FileName只能一个个获取 所以在此循环去取路径下的文件名 比较笨 但实用
public List<string> getFileName(string url)
{
string filePath = string.Format(System.Web.HttpContext.Current.Server.MapPath("doc/{0}"), url);//路径
DirectoryInfo dir = new DirectoryInfo(filePath);
FileInfo[] fileInfo = dir.GetFiles();
List<string> fileNames = new List<string>();
foreach (FileInfo item in fileInfo)
{
fileNames.Add(item.Name);
}
return fileNames;
}
特别说明:
此方法适用于单个文件2G以下的多文件上传。下次更新超2G的多文件代码
关于swfupload里上传后上传列队里的信息会自动消失 可以自己根据需要自己设置如下属性
fileprogress.js 里的
this.setTimer(setTimeout(function () {
oSelf.disappear();
}, 10000));
注释即不消失
js：
file_size_limit: "0" -- 不限制上传文件大小
file_types: "*.*", --- 不限制文件格式
post_params: {
"ASPSESSID": "<%=Session.SessionID %>",
"type": type,
"id": id
}, --- 传值 在ashx中直接 string type = context.Request["type"]; 获取
