以下是我班级的一些属性。还有另一个类 DNRole

的公共对象
    private Int32 _IDMarketingCampaign;
    private String _Name;

    public Int32 IDMarketingCampaign
    {
        get { return _IDMarketingCampaign; }
        set { _IDMarketingCampaign = value; }
    }
    public String Name
    {
        get { return _Name; }
        set { _Name = value; }
    }
    public DPRole DNRole = new DPRole();

在同一个类中,我有一个方法returnig List。除了我的常规字段,我还填充了我的DNRole对象的一个​​字段:

listItem.DNRole.RoleName = dr [“RoleNameFK”]。ToString();

我的问题是......这是否合法,是否应该如何完成,如果是,我如何在girdview中显示数据?

public List<MarketingCampaign> SelectForGrid(string strRoleName)
        {
            List<MarketingCampaign> lista = new List<MarketingCampaign>();
            SqlCommand command = new SqlCommand("fra_MarketingCampaignSelectForGrid ", conn);
            command.CommandType = CommandType.StoredProcedure;
            command.Parameters.Add("RoleName", SqlDbType.VarChar).Value = strRoleName;
            SqlDataReader dr = null;
            try
            {
                conn.Open();
                dr = command.ExecuteReader();
                while (dr.Read())
                {
                    MarketingCampaign listItem = new MarketingCampaign();

                    listItem.IDMarketingCampaign = Convert.ToInt32(dr["IDMarketingCampaign"]);
                    listItem.Name = dr["Name"].ToString();
                    listItem.DNRole.RoleName = dr["RoleNameFK"].ToString();
                    ...
                    lista.Add(listItem);
                }

你可以使用ObjectDataSource - 来包装调用SelectForGrid,你也可以直接将List绑定到你的GridView:

MyGrid.DataSoure = some. SelectForGrid();
MyGrid.DataBind();

当数据以* .aspx / ascx代码绑定时,您需要将列绑定到属性: Eval和Bind允许您按名称进行,但更快的方式使用显式强制转换为MarketingCampaign。

<asp:TemplateField >
     <ItemTemplate> 
        <%#((MarketingCampaign)Container.DataItem).Name%> 
     </ItemTemplate>

List<MarketingCampaign> mk= obj.SelectForGrid("Role");
GridView1.DataSource = mk;
GridView1.DataBind();
