以下に、ウェブサイトのカレンダーのコードを示します。問題は、このコードの読み込みに約 8 ～ 10 秒かかることです。読み込み時間を最小限に抑える方法を見つけた方がいらっしゃいましたら、よろしくお願いします。

「Begivenheder.Get_Begivenhed_By_Date」コードはこちらです。
public static List<Begivenheder> Get_Begivenhed_By_Date(int år, int måned, int dag, SqlConnection connection)
{
List<Begivenheder> result = new List<Begivenheder>();
using (var command = new SqlCommand("Select ID, FK_Begivenhed_ID from Begivenhed_Datoer where Dag=" + dag + " and Måned=" + måned + " and År=" + år, connection))
{
SqlDataReader reader = command.ExecuteReader();
try
{
while (reader.Read())
{
Begivenheder b = new Begivenheder();
b.Dato_ID = reader.GetInt32(0);
b.ID = reader.GetInt32(1);
b.Dato_Day = dag;
b.Dato_Month = måned;
b.Dato_Year = år;
result.Add(b);
}
}
finally
{
reader.Close();
}
foreach (Begivenheder b in result)
{
b.begivenhed = Begivenheder.Get_Begivenhed_By_ID(b.ID, connection);
}
}
return result;
}
私はそれがコードの束であることを知っていますが、それを減らす方法がわかりません。
