DateTimePicker 构造函数

定义

初始化 DateTimePicker 类的新实例。

public:
 DateTimePicker();
public DateTimePicker ();
Public Sub New ()

示例

下面的代码示例创建控件的新实例 DateTimePicker 并对其进行初始化。 控件的 CustomFormat 属性已设置。 此外, ShowCheckBox 设置 属性以便控件显示 CheckBox,设置 ShowUpDown 属性以便控件显示为旋转按钮控件 (也称为向上向下控件) 。

public:
   void CreateMyDateTimePicker()
   {
      // Create a new DateTimePicker control and initialize it.
      DateTimePicker^ dateTimePicker1 = gcnew DateTimePicker;
      
      // Set the MinDate and MaxDate.
      dateTimePicker1->MinDate = DateTime(1985,6,20);
      dateTimePicker1->MaxDate = DateTime::Today;
      
      // Set the CustomFormat string.
      dateTimePicker1->CustomFormat = "MMMM dd, yyyy - dddd";
      dateTimePicker1->Format = DateTimePickerFormat::Custom;
      
      // Show the CheckBox and display the control as an up-down control.
      dateTimePicker1->ShowCheckBox = true;
      dateTimePicker1->ShowUpDown = true;
   }
public void CreateMyDateTimePicker()
{
   // Create a new DateTimePicker control and initialize it.
   DateTimePicker dateTimePicker1 = new DateTimePicker();

   // Set the MinDate and MaxDate.
   dateTimePicker1.MinDate = new DateTime(1985, 6, 20);
   dateTimePicker1.MaxDate = DateTime.Today;

   // Set the CustomFormat string.
   dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd";
   dateTimePicker1.Format = DateTimePickerFormat.Custom;

   // Show the CheckBox and display the control as an up-down control.
   dateTimePicker1.ShowCheckBox = true;
   dateTimePicker1.ShowUpDown = true;
}
Public Sub CreateMyDateTimePicker()
    ' Create a new DateTimePicker control and initialize it.
    Dim dateTimePicker1 As New DateTimePicker()
    
    ' Set the MinDate and MaxDate.
    dateTimePicker1.MinDate = New DateTime(1985, 6, 20)
    dateTimePicker1.MaxDate = DateTime.Today
    
    ' Set the CustomFormat string.
    dateTimePicker1.CustomFormat = "MMMM dd, yyyy - dddd"
    dateTimePicker1.Format = DateTimePickerFormat.Custom
    
    ' Show the CheckBox and display the control as an up-down control.
    dateTimePicker1.ShowCheckBox = True
    dateTimePicker1.ShowUpDown = True
End Sub
