I guess you are looking for this,hope it will help you

public DataTable GetAllEmployees()
{
DataTable dt = new DataTable();
SqlConnection con = new SqlConnection(conString);

try
{
SqlCommand cmd = new SqlCommand("StoredprocedureName", con);
cmd.CommandType = CommandType.StoredProcedure;

con.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
}
}

At last Convert DataTable to List as per your requirements.

You can return a DataTable and bind that directly. Let me update your code.

C#

public DataTable GetTimeZones()
{
    DataTable dtTimeZones = new DataTable();

    SqlCommand cmd = new SqlCommand("sp_EP_GetTimeZones;", con);
    cmd.CommandType = CommandType.StoredProcedure;

    SqlDataAdapter adapter = new SqlDataAdapter(cmd);
    adapter.Fill(dtTimeZones);
    
    return dtTimeZones;
}

While binding, you can do like...

C#

ddlTimeZones.DataSource = GetTimeZones();
ddlTimeZones.DataTextField = "Zonetime";
ddlTimeZones.DataValueField = "Zonetime";
ddlTimeZones.DataBind();

I have assigned Zonetime for to both Value and ID. If you have any other column value, then just fetch that in procedure and update here.
