如何在毫秒图表中绑定24小时格式的日期

public void bindChartDetail()
{
    objUser = (UserEntity)Session["User"];

    if (objUser == null)
    {
        Response.Redirect("~/Default.aspx");
    }
    DateTime fromDate;
    DateTime toDate;
    String strDomainName = "";

    if (ddlDomainName.SelectedIndex > 0)
    {
        strDomainName = ddlDomainName.SelectedItem.Text.ToString();
    }
    else
    {
        strDomainName = lblDomainName.Text;
    }
    if (txtFromDate.Text != "")
    {
        fromDate = DateTime.ParseExact(txtFromDate.Text, "dd-MM-yyyy", null);
    }
    else
    {
        fromDate = toDate = System.DateTime.Now;
    }
    if (txtToDate.Text != "")
    {
        toDate = DateTime.ParseExact(txtToDate.Text, "dd-MM-yyyy", null);
    }
    else
    {
        toDate = System.DateTime.Now;
    }

    ReportBL objReport = new ReportBL();
    PagedDataSource rptPager = null;
    DataTable dt = null;
    try
    {
        dt = new DataTable();
        dt = objReport.USERWISEACCOUNTINGINFORMATIONWITHINBOUNDOUTBOUND(strDomainName, 0, fromDate, toDate);
        if (dt == null)
        {
            if (dt.Rows.Count > 0)
            {
               byte[] YPointMember = new byte[dt.Rows.Count];
               ChartAreas[0].AxisX.LabelStyle.Format = "HH:mm:ss";
               //DateTime[] YPointMember = new DateTime[dt.Rows.Count];
                for (int count = 0; count < dt.Rows.Count; count++)
                {
                    YPointMember[count] = Convert.ToByte(dt.Rows[count]["INBOUND"]);
                    //YPointMember[count] = (dt.Rows[count]["connectdatetime"]);
                }
                Chart1.Series[0].Points.DataBindXY(YPointMember);
                Chart1.Series[0].BorderWidth = 1;
                Chart1.Series[0].ChartType = SeriesChartType.Line;
            }

我的数据库中有两个字段：inbound和date。我想以24小时的格式在x轴上显示date，但我不知道，因为我是图表控制的新手。
