问题描述

protected void grdbookstatus_RowDataBound1(object sender, GridViewRowEventArgs e)
        {
            DataTable dt =(DataTable)ViewState["dt"];
            DateTime indianTime = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, INDIAN_ZONE);
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
              
                CheckBox chk = (CheckBox)e.Row.FindControl("CheckBox1");
                Label lbl = (Label)e.Row.FindControl("Label2");
                Label lblpname = (Label)e.Row.FindControl("lblpname");
                if (dt.Rows.Count > 0)
                {
                    for (int i = 0; i < dt.Rows.Count; i++)
                    {


                        if (chk.Text == Convert.ToString(dt.Rows[i]["AppointmentTime"]))
                        {
                            chk.Checked = true;
                            chk.Enabled = false;
                            lbl.Text = "Booked";
                            lblpname.Text = Convert.ToString(dt.Rows[i]["Patient_Name"]);
                            e.Row.Cells[1].ForeColor = System.Drawing.Color.Blue;
                            e.Row.Cells[2].ForeColor = System.Drawing.Color.Blue;
                            e.Row.Cells[3].ForeColor = System.Drawing.Color.Blue;
                            e.Row.BackColor = System.Drawing.Color.Red;
                            break;
                        }
                       // else if (Convert.ToString(dt.Rows[i]["AppointmentTime"]) > indianTime)
                        else if (Convert.ToDateTime(dt.Rows[i]["AppointmentTime"]).Hour > indianTime.Hour)
                        {
                            chk.Enabled = false;
                        }
                        else 
                        {
                            lbl.Text = "Available";
                          //  Button1.Visible = false;
                         
                        }
                    }
                }
                else
                {

你好，< br $>


您需要使用 DateTime 。比较方法。

Hi,

You need to use DateTime.Compare method.

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";

Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
// The example displays the following output: 
//    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM

祝你好运。

Good luck.
