  • Jesus, I suggest you write the statement of your question (I will edit to improve the formatting of the code), to make it as readable as possible.

I made a code snippet with the idea to be used in your context:

//Variável que representa uma data e um horário qualquer
DateTime data = new DateTime(2010, 10, 10, 3, 00, 00);

//Variável para armazenar o formato do horário (AM ou PM) 
string formatoHorario = data.ToString("tt", CultureInfo.InvariantCulture);

//Variável que armazena o horário
string horario = data.ToString("hh:mm");

    // Se o formato do horário é AM, iremos pegar os dados e jogar no dropdown AM, caso contrário jogamos no dropdown PM
    if (formatoHorario == "AM") 
    {
        dropDownListAM.DataSource = listaHorariosAM;
        dropDownListAM.DataBind();
    }
    else 
    {
        dropDownListPM.DataSource = listaHorariosPM;
        dropDownListPM.DataBind();
    }

Remembering that it is just a functional example for you to adapt to your reality.
