DatarowsForOneDay = dt.Select(
    dt.Columns[0].Caption + "='" + x.ToString("dd/MM/yyyy HH") + "'");

doesn’t work, but

DatarowsForOneDay = dt.Select(
    dt.Columns[0].Caption + "='" + x.ToString("dd/MM/yyyy") + "'");

works.

So how can I select the date with a same hour?

Variable x type is DateTime.

    Use SUBSTRING or LIKE

    or

    dt.Columns[0].Caption + " LIKE '" + x.ToString("dd/MM/yyyy HH") + "*'"
