Filter on Time in date time type field.

Hi
Nilesh here,
I have a dataset with a date time type filed. I want to filter that date time field. I want to do filter by time not whole date.

Suppose there is a date time like "2012-04-04 10:34:21", then I want to filter on only time like datetimefiled>="10:34:21".

So how can I solve this?
Thanks in advance.

You can use LINQ for it .

Example:
            DataTable dt = new DataTable();
            dt.Columns.Add(new DataColumn("ID",typeof(int)));
            dt.Columns.Add(new DataColumn("Date",typeof(DateTime)));

            DataRow dr = dt.NewRow();
            dr["ID"] = 1;
            dr["Date"] = new DateTime(2012,4,4,10,10,10);
            dt.Rows.Add(dr);
            dr = dt.NewRow();
            dr["ID"] = 1;
            dr["Date"] = new DateTime(2012,4,4,11,11,11);
            dt.Rows.Add(dr);
            dr = dt.NewRow();
            dr["ID"] = 1;
            dr["Date"] = new DateTime(2012,4,4,12,12,12);
            dt.Rows.Add(dr);

            DateTime ToCompare= new DateTime(2012,4,4,10,15,30);

            DataRow[] rows = dt.Rows.Cast<DataRow>().Where(x => (int.Parse(((DateTime)x["Date"]).ToString("HH")) * 3600 +
                                                                 int.Parse(((DateTime)x["Date"]).ToString("mm")) * 60 +
                                                                 int.Parse(((DateTime)x["Date"]).ToString("ss")))
                                                                 >= (ToCompare.Hour*3600 + ToCompare.Minute*60+ToCompare.Second)).ToArray();

you can use Dataview for  the dataset

DataView dv = new DataView(yourdataset);
dv.RowFilter="YourDatecolumn >= #yourdate#";

Also you can refer the below link:

Thanks dear kswathi,

I do not want to filter on date, I want to filter on only time like dateTimeFiled>="10:30" like that. No need to check date. its need to check only time.

Example I've provided will search all the rows with the time that are after the one I've provided (after 10:15:30). You'll need to convert it to seconds to compare the values. You can't just compare the string "11:11:11" >= "10:15:30"
