示例

下面的代码示例演示如何使用该 Value 属性检索当前日期值。 首先，该示例显示 Value 属性。 然后，该示例将属性递增 Value 一天，并再次显示属性值。

public:
   MyClass()
   {
      // Create a new DateTimePicker
      DateTimePicker^ dateTimePicker1 = gcnew DateTimePicker;
      array<Control^>^ myClassControls = {dateTimePicker1};
      Controls->AddRange( myClassControls );
      MessageBox::Show( dateTimePicker1->Value.ToString() );

      dateTimePicker1->Value = DateTime::Now.AddDays( 1 );
      MessageBox::Show( dateTimePicker1->Value.ToString() );
   }

public MyClass()
{
   // Create a new DateTimePicker
   DateTimePicker dateTimePicker1 = new DateTimePicker();
   Controls.AddRange(new Control[] {dateTimePicker1});
   MessageBox.Show(dateTimePicker1.Value.ToString());

   dateTimePicker1.Value = DateTime.Now.AddDays(1);
   MessageBox.Show(dateTimePicker1.Value.ToString());
}

Public Sub New()
   ' Create a new DateTimePicker
   Dim dateTimePicker1 As New DateTimePicker()
   Controls.AddRange(New Control() {dateTimePicker1})
   MessageBox.Show(dateTimePicker1.Value.ToString())
   
   dateTimePicker1.Value = DateTime.Now.AddDays(1)
   MessageBox.Show(dateTimePicker1.Value.ToString())
End Sub

注解

Value如果属性尚未在代码或用户中更改，则会将其设置为当前日期和时间 (DateTime.Now) 。
