推荐答案

就您的第一个要求而言，您几乎已经拥有它，您只需要检查您的组件/变量名称.

As far as your first requirement you almost had it you just need to check your component/variable names.

if (FileUpload2.HasFile)
{
  string fn2 = Guid.NewGuid() + System.IO.Path.GetExtension(FileUpload2.FileName);
  string sp = Server.MapPath("pics/houses/Architecture");
  sp += "/" + fn2;
  FileUpload2.PostedFile.SaveAs(sp);
  obj.architecture = fn2;
}

还要注意使用System.IO.Path.GetExtension来获取文件的扩展名，它比substring/lastindex方法要干净一些.

对于您的错误，您需要指定错误发生的位置.

Also notice the use of System.IO.Path.GetExtension to get the extension of the file, it''s a bit cleaner than the substring/lastindex method.

As for your error you need to specify where it occurs.
