C＃实例化类问题

Question

i am trying to instantiate classes:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using RadarGraphInsertDLL;


namespace EnterData.DataEntry
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void gaia_lom_Inserting(object sender, SqlDataSourceCommandEventArgs e)
        {

        }

        protected void SubmitData(object sender, EventArgs e)
        {
            LOMDLL.Main_Lom_Form MainLomFormTable = PopulateMainForm();
            IList<LOMDLL.Lom_Batch> BatchTable = PopulateBatchTable();
            IList<LOMDLL.Lom_Problem> ProblemTable = PopulateProblemTable();
            IList<LOMDLL.Lom_Specimen> SpecimenTable = PopulateSpecimenTable();
        }


    }
}

but getting this error:

Error   19  The type name 'Main_Lom_Form' does not exist in the type 'EnterData.DataEntry.WebForm1.LOMDLL'  C:\Documents and Settings\agordon\My Documents\Visual Studio 2008\Projects\lomdb\EnterData\DataEntry\DAL.cs 64  55  EnterData

but i do have these!!

public class Main_Lom_Form
{
    public int lom_number {get;set;}
    public DateTime occurrence_date {get;set;}
    public DateTime report_date {get;set;}
    public string report_by {get;set;}
    public string identified_by {get;set;}
    public string section_c_issue_error_identified_by{get;set;}
    public string section_c_comments{get;set;}
    public string section_d_investigation{get;set;}
    public string section_e_corrective_action{get;set;}
    public string section_f_comments{get;set;}
    public string pre_practice_code{get;set;}
    public string pre_contact{get;set;}
}
public class Lom_Batch
{
    public int lom_number { get; set; }
    public string batch { get; set; }
}
public class Lom_Problem
{
    public int lom_number { get; set; }
    public string problem { get; set; }
}
public class Lom_Specimen
{
    public int lom_number { get; set; }
    public string specimen { get; set; }
}

what is the reason i cannot instantiate the classes?

Answer 1

I'm going to assume that there are other compiler errors here that you aren't showing us. Drop the static keyword from the class definition. You can't instantiate a static class.

Answer 2

You aren't giving us the full list of compiler error messages. We can't really help without that. You don't know what the problem is so it's unwise to pick and choose which clues you share
