我有一个访问数据库，其中一个字段是复选框列表，允许我们的管理员选择作业。由于该垃圾邮件预防机制，我无法发布图片，请允许我将此字段描述如下：

工作

（复选框）园艺

（复选框）地毯清洁

（勾选）厕所清洁

（复选框）窗户清洁

管理员应该能够选择多个工作或根本没有工作，这取决于他的心情。

我必须使用 C# 创建一个 UI，那么如何以编程方式从 C# 访问此字段，修改后如何将其放回数据库？

编辑：此字段在 Access 2010 中如下所示：http: //i48.tinypic.com/9k1204.jpg

下面是我用来从数据库中获取行的代码

public List<Contractor> GetContractors()
    {
        //connect to local database file and read everything from contractor table
        OleDbConnection myConnection = new OleDbConnection(/*local database file*/);
        myConnection.Open();
        string sql = "SELECT * FROM Contractors";
        OleDbCommand myCommand = new OleDbCommand(sql, myConnection);
        OleDbDataReader myReader = myCommand.ExecuteReader();

        //contractor lists that to be returned
        List<Contractor> contractors = new List<Contractor>();

        //raw data from database
        ArrayList records = new ArrayList();
        while (myReader.Read())
        {
            Hashtable row = new Hashtable();
            for (int i = 0; i < myReader.FieldCount; i++)
            {
                row.Add(myReader.GetName(i), myReader[i]);
            }
            records.Add(row);
        }

        //fetch rows, and construct a temp Contractor based on rows
        for (int i = 0; i < records.Count; i++)
        {
            Contractor tempContractor = new Contractor();
            Hashtable row = (Hashtable)records[i];
            tempContractor.ID = Convert.ToInt32(row["ID"]);
            tempContractor.FamilyName = Convert.ToString(row["FamilyName"]);
            tempContractor.GivenNames = Convert.ToString(row["GivenNames"]);
            tempContractor.Address = Convert.ToString(row["Address"]);
            tempContractor.Phone = Convert.ToString(row["Phone"]);
            tempContractor.Mobile = Convert.ToString(row["Mobile"]);
            tempContractor.Email = Convert.ToString(row["Email"]);
            tempContractor.DateOfBirth = Convert.ToDateTime(row["DOB"]);
            tempContractor.Status = this.getTableItem(contractorStatus, Convert.ToInt32(row["Status"]));
            tempContractor.Comments = Convert.ToString(row["Comments"]);

            //+++++++++++++++++++++++++++++++++++
            tempContractor.Jobs = Convert.ToString(row["Jobs"]); //<------ this is how I try to fetch the dropdown list field in database, it doesn't work
            //++++++++++++++++++++++++++++++++++++
            contractors.Add(tempContractor);
        }

        return contractors;
    }
