错误信息中提示错误可能在32行.
arrfile.Add(f.Length/1000);
文件长度有问题.

最好能多贴一些代码.

这就是全部的代码，不知道问题在哪里？

FileInfo f = new FileInfo(fullname);
这是错的,不存在fullname.
修改:
if (file.HasFile)
        {
            var f = file.PostedFile;
            ArrayList arrfile = new ArrayList();
            arrfile.Add(Session["uname"].ToString());
            arrfile.Add(f.Name);

            arrfile.Add(f.Extension);//这里自己写个方法获取扩展名
            arrfile.Add(f.ContentLength/1000);
            arrfile.Add(tmessage.Text.Trim().ToString());
            file.SaveAs(Server.MapPath("UploadFile") + "\\" + f.Name);
            file fmethod = new file();
            fmethod.add_file(arrfile);
            this.tmessage.Text = "";
            Response.Write("<script>alert('文件上传成功！')</script>");
        }
        else
        {

这个是公文发送的代码，也有添加文档上传的功能，这个就可以实现，我是不是可以根据这个修改之前那个代码？然后怎么修改呢？

没有什么问题.

我想根据这个改我之前那个报错的代码，可是不知道怎么改？我按你给的那个试着改了改，但还是不行。。。
