在此代码中，将文件保存到磁盘时会发生错误。

if (ModelState.IsValid)
{
    if (account.file != null)
    {
        string FileName = Path.GetFileName(account.file.FileName);
        //Save files to disk
        account.file.SaveAs(Server.MapPath("Uploads/" + FileName));

        //Add Entry to DataBase
        string conection = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
        using (SqlConnection con = new SqlConnection(conection))
        {

            string InsertAccount = "Insert into tblUser (FirstName,LastName,EmailAdress,UserName,Password,UserImage) values(@fname,@lname,@emailadress,@username,@password,@Userimagepath)";
            SqlCommand cmd = new SqlCommand(InsertAccount, con);
            cmd.Parameters.AddWithValue("@fname", account.FirstName);
            cmd.Parameters.AddWithValue("@lname", account.LastName);
            cmd.Parameters.AddWithValue("@emailadress", account.EmailAddress);
            cmd.Parameters.AddWithValue("@username", account.Username);
            cmd.Parameters.AddWithValue("@password", account.Password);
            cmd.Parameters.AddWithValue("@UserimagePath", "Uploads/" + FileName);
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }

    }
}
