指定 DateTimePicker 控件显示的日期和时间格式。
public enum class DateTimePickerFormatC#
public enum DateTimePickerFormattype DateTimePickerFormat = Public Enum DateTimePickerFormat- 继承
| 名称 | 值 | 说明 |

| Time | 4 | DateTimePicker 控件以用户操作系统设置的时间格式显示日期/时间值。 |
下面的代码示例演示如何通过将 设置为 FormatDateTimePickerFormat 值来初始化 DateTimePicker 对象。 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 );
}
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 "
' Add the DateTimePicker to the form.
Me.Controls.Add(Me.DateTimePicker1)
End Sub
此枚举由成员（如 ） DateTimePicker.Format使用。
备注
实际日期/时间格式由用户操作系统中设置的日期、时间和区域设置决定。
