示例

下面的代码示例演示如何通过设置 DropDownAlign、、 ValueFormat和 CustomFormat 属性来初始化 DateTimePicker 。 若要运行此示例，请将以下代码粘贴到窗体中，并从窗体的构造函数或Load事件处理方法调用 InitializeDateTimePicker 。

internal:
   // Declare the DateTimePicker.
   System::Windows::Forms::DateTimePicker^ DateTimePicker1;

private:
   void InitializeDateTimePicker()
   {
      // Construct the DateTimePicker.
      this->DateTimePicker1 = gcnew System::Windows::Forms::DateTimePicker;
      
      //Set size and location.
      this->DateTimePicker1->Location = System::Drawing::Point( 40, 88 );
      this->DateTimePicker1->Size = System::Drawing::Size( 160, 21 );
      
      // Set the alignment of the drop-down MonthCalendar to right.
      this->DateTimePicker1->DropDownAlign = LeftRightAlignment::Right;
      
      // Set the Value property to 50 years before today.
      DateTimePicker1->Value = System::DateTime::Now.AddYears(  -50 );
      
      //Set a custom format containing the string "of the year"
      DateTimePicker1->Format = DateTimePickerFormat::Custom;
      DateTimePicker1->CustomFormat = "MMM dd, 'of the year' yyyy ";
      
      // Add the DateTimePicker to the form.
      this->Controls->Add( this->DateTimePicker1 );
   }

// Declare the DateTimePicker.
internal System.Windows.Forms.DateTimePicker DateTimePicker1;

private void InitializeDateTimePicker()
{
    // Construct the DateTimePicker.
    this.DateTimePicker1 = new System.Windows.Forms.DateTimePicker();

    //Set size and location.
    this.DateTimePicker1.Location = new System.Drawing.Point(40, 88);
    this.DateTimePicker1.Size = new System.Drawing.Size(160, 21);
    
    // Set the alignment of the drop-down MonthCalendar to right.
    this.DateTimePicker1.DropDownAlign = LeftRightAlignment.Right;

    // Set the Value property to 50 years before today.
    DateTimePicker1.Value = System.DateTime.Now.AddYears(-50);

    //Set a custom format containing the string "of the year"
    DateTimePicker1.Format = DateTimePickerFormat.Custom;
    DateTimePicker1.CustomFormat = "MMM dd, 'of the year' yyyy ";

    // Add the DateTimePicker to the form.
    this.Controls.Add(this.DateTimePicker1);
}

' Declare the DateTimePicker.
Friend WithEvents DateTimePicker1 As System.Windows.Forms.DateTimePicker


Private Sub InitializeDateTimePicker()

    ' Construct the DateTimePicker.
    Me.DateTimePicker1 = New System.Windows.Forms.DateTimePicker

    'Set size and location.
    Me.DateTimePicker1.Location = New System.Drawing.Point(40, 88)
    Me.DateTimePicker1.Size = New Size(160, 21)
    
    ' Set the alignment of the drop-down MonthCalendar to right.
    Me.DateTimePicker1.DropDownAlign = LeftRightAlignment.Right

    ' Set the Value property to 50 years before today.
    DateTimePicker1.Value = (DateTime.Now.AddYears(-50))

    'Set a custom format containing the string "of the year"
    DateTimePicker1.Format = DateTimePickerFormat.Custom
    DateTimePicker1.CustomFormat = "MMM dd, 'of the year' yyyy "

    ' Add the DateTimePicker to the form.
    Me.Controls.Add(Me.DateTimePicker1)
End Sub
