指定 DateTimePicker 控制項顯示的日期時間格式。
public enum class DateTimePickerFormatC#
public enum DateTimePickerFormattype DateTimePickerFormat = Public Enum DateTimePickerFormat- 繼承
| 名稱 | 值 | Description |
|---|---|---|
| Custom | 8 | DateTimePicker 控制項以自訂格式來顯示日期時間值。 如需詳細資訊，請參閱CustomFormat。 |
| Long | 1 | DateTimePicker 控制項以使用者的作業系統所設定的長日期格式來顯示日期時間值。 |
| Short | 2 | DateTimePicker 控制項以使用者的作業系統所設定的短日期格式來顯示日期時間值。 |
| Time | 4 | DateTimePicker 控制項以使用者的作業系統所設定的時間格式來顯示日期時間值。 |
下列程式碼範例示範藉由將 設定 Format 為 DateTimePickerFormat 值來初始化 DateTimePicker 物件。 若要執行此範例，請將下列程式碼貼到表單中，並從表單的建構函式或 Load 事件處理方法呼叫 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 );
}
C#
// 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 "

Me.Controls.Add(Me.DateTimePicker1)
End Sub
這類成員 DateTimePicker.Format 會使用此列舉。
注意
實際的日期/時間格式取決於使用者作業系統中設定的日期、時間和區域設定。
