如何在c#中将时间格式从h:m tt转换为hh:mm tt

Question

我正在尝试在下拉列表中显示时间。我设法使用以下代码做到了这一点：-

        DateTime dtTime = new DateTime(2015,01,01,00,00,00);

        DataTable dt = new DataTable();
        dt.Columns.Add("time");

        for (int i = 0; i < 48; i++)
        {
            string tm = dtTime.ToShortTimeString();
            DataRow dr = dt.NewRow();
            dr["time"] = tm;
            dt.Rows.Add(dr);

            dtTime = dtTime.AddMinutes(30);
        }

        ddlTime.DataSource = dt;
        ddlTime.DataTextField = "time";
        ddlTime.DataValueField = "time";
        ddlTime.DataBind();

输出是：-

现在，我想将格式设为 hh:mm tt。例如，1:00 AM 应该是 01:00 AM。谁能帮我？谢谢
