SelectionRange(DateTime, DateTime)

Menginisialisasi instans SelectionRange baru kelas dengan tanggal awal dan akhir yang ditentukan.

public:
 SelectionRange(DateTime lower, DateTime upper);

public SelectionRange (DateTime lower, DateTime upper);

new System.Windows.Forms.SelectionRange : DateTime * DateTime -> System.Windows.Forms.SelectionRange

Public Sub New (lower As DateTime, upper As DateTime)

Parameter

lower

DateTime

Tanggal mulai di SelectionRange.

upper

DateTime

Tanggal akhir di SelectionRange.

Contoh

Contoh berikut mengatur SelectionRange properti MonthCalendar kontrol berdasarkan dua tanggal yang dimasukkan ke dalam dua TextBox kontrol saat Button diklik. Kode ini mengasumsikan instans baru kontrol MonthCalendar , dua TextBox kontrol, dan Button telah dibuat pada Form. Anda mungkin mempertimbangkan untuk menambahkan kode untuk memvalidasi Text yang ditetapkan ke kotak teks untuk memverifikasi bahwa kode tersebut berisi tanggal yang valid.

private:
   void button1_Click( Object^ sender, EventArgs^ e )
   {
      // Set the SelectionRange with start and end dates from text boxes.
      try
      {
         monthCalendar1->SelectionRange = gcnew SelectionRange(
            DateTime::Parse( textBox1->Text ),
            DateTime::Parse( textBox2->Text ) );
      }
      catch ( Exception^ ex ) 
      {
         MessageBox::Show( ex->Message );
      }
   }

private void button1_Click(object sender,
                           EventArgs e)
{
   // Set the SelectionRange with start and end dates from text boxes.
   try
   {
      monthCalendar1.SelectionRange = new SelectionRange(
        DateTime.Parse(textBox1.Text),
        DateTime.Parse(textBox2.Text));
   }
   catch(Exception ex)
   {
      MessageBox.Show(ex.Message);
   }
}

Private Sub button1_Click(sender As Object, e As EventArgs)
   ' Set the SelectionRange with start and end dates from text boxes.
   Try
      monthCalendar1.SelectionRange = New SelectionRange( _
        DateTime.Parse(textBox1.Text), _
        DateTime.Parse(textBox2.Text))
   Catch ex As Exception
      MessageBox.Show(ex.Message)
   End Try
End Sub

Keterangan

Catatan

lowerDateTime Jika nilai lebih besar dari upperDateTime nilai , lower nilai akan ditetapkan ke End properti alih-alih Start properti .
