asp COMMON组件解决方案

asp COMMON组件
第一次用这个。为什么报“ “Zznode.OA.Common.Data.DepData”并不包含“DEPJG_FIELD”的定义
”
DepData 代码:

C# code

namespace Zznode.OA.Common.Data{    /// <summary>    /// DepData 的摘要说明。    /// </summary>    public class DepData : DataSet    {        public const string STREET_FIELD = "Street";        public const string POSTCODE_FIELD = "PostCode";        public const string SORTORDER_FIELD = "SortOrder";        public const string NUMBER_FIELD = "AllowedEmpNumber";        [color=#FF0000]public const string DEPJG_FIELD = "Dep_JG";[/color]            private void BuildTable()        {            cols.Add(STREET_FIELD,typeof(System.String));            cols.Add(POSTCODE_FIELD,typeof(System.String));            cols.Add(SORTORDER_FIELD, typeof(System.Int16));            cols.Add(NUMBER_FIELD, typeof(System.Int16));            [color=#FF0000]cols.Add(DEPJG_FIELD,typeof(System.String));[/color]            Tables.Add(table);        }        public DepData()        {            BuildTable();        }    }}

C# code

 //创建部门        private void CreateNewDep()        {            DepData depData = new DepData();            DataTable depTB = depData.Tables[DepData.DEP_TABLE_NAME];                                    DataRow row = depTB.NewRow();            row[DepData.BRANCHID_FIELD] = Convert.ToInt32(lstBranch.SelectedItem.Value,10);            row[DepData.DEPNAME_FIELD] = txtName.Text.ToString().Trim();            row[DepData.MANAGER_FIELD] = txtManager.Text.ToString().Trim();            row[DepData.TEL1_FIELD] = txtTel1.Text.ToString().Trim();            row[DepData.TEL2_FIELD] = txtTel2.Text.ToString().Trim();            row[DepData.FAX_FIELD] = txtFax.Text.ToString().Trim();            row[DepData.POSTCODE_FIELD] = txtPostCode.Text.ToString().Trim();            row[DepData.PROVINCE_FIELD] = txtProvince.Text.ToString().Trim();            row[DepData.CITY_FIELD] = txtCity.Text.ToString().Trim();            row[DepData.DISTRICT_FIELD] = txtDistrict.Text.ToString().Trim();            row[DepData.STREET_FIELD] = txtStreet.Text.ToString().Trim();            row[DepData.DEPJG_FIELD] = txtDep_XZ.Text.ToString().Trim();                       depTB.Rows.Add(row);            bool result = (new DepSystem()).CreateDep(depData);        }
