在Web开发中，有很多可以上传的组件模块，利用HTML的File控件的上传也是一种办法，不过这种方式，需要处理的细节比较多，而且只能支持单文件的操作。在目前Web开发中用的比较多的，可能uploadify（参考http://bine(uploadPath, newFileName);
LogTextHelper.Info(newFilePath);
file.SaveAs(newFilePath);
bool uploaded = File.Exists(newFilePath);

#endregion

if (uploaded)
{
#region 文件保存成功后，写入附件的数据库记录
//AttachmentInfo attachmentInfo = new AttachmentInfo();
//attachmentInfo.EditorTime = DateTime.Now;
//attachmentInfo.FileExtend = extenstion;
//attachmentInfo.FileName = folader + "/" + newFileName;
//attachmentInfo.OldFileName = oldFileName;
//attachmentInfo.Size = size;
//attachmentInfo.Guid = guid;
//BLLFactory<Attachment>.Instance.Insert(attachmentInfo);
#endregion
