MonthCalendar 类

表示一个 Windows 控件，该控件使用户能够使用可视月历显示来选择日期。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
<ComVisibleAttribute(True)> _
<ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)> _
Public Class MonthCalendar
    Inherits Control
用法
Dim instance As MonthCalendar

[ComVisibleAttribute(true)] 
[ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch)] 
public class MonthCalendar : Control

[ComVisibleAttribute(true)] 
[ClassInterfaceAttribute(ClassInterfaceType::AutoDispatch)] 
public ref class MonthCalendar : public Control

/** @attribute ComVisibleAttribute(true) */ 
/** @attribute ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) */ 
public class MonthCalendar extends Control

ComVisibleAttribute(true) 
ClassInterfaceAttribute(ClassInterfaceType.AutoDispatch) 
public class MonthCalendar extends Control

备注

MonthCalendar 控件允许用户使用可视显示来选择日期。通过设置 MinDate 和 MaxDate 属性，可以限制可选择的日期和时间。

通过设置 ForeColor、Font、TitleBackColor、TitleForeColor、TrailingForeColor 和 BackColor 属性，可以更改控件日历部分的外观。

MonthCalendar 控件由操作系统绘制，因此决不会引发 Paint 事件。如果需要为 MonthCalendar 控件提供自定义的外观，则应重写 OnPrint 方法，调用 OnPrint 的基实现，然后再执行自定义绘图。

如果需要将自定义日期格式和选择限制为只用于一个日期，您可以考虑使用 DateTimePicker 控件，而不是 MonthCalendar。使用 DateTimePicker 可避免许多需要验证日期／时间值的情况。

有关月历控件的更多信息，请参见位于 https://www.microsoft.com/china/msdn 上的 Platform SDK 文档中的“Month Calendar Controls”（月历控件）。

提示

如果将 ShowTodayCircle 设置为 true，在启用视觉样式时使用 MonthCalendar 会导致不能正确绘制 MonthCalendar 控件的选择范围，并且在某个正方形中还会包含当天的日期。

示例

下面的代码示例显示一个包含 MonthCalendar 控件的窗体，而且该窗体显示一个日历年。该示例演示如何设置 BackColor、ForeColor、TitleBackColor、TitleForeColor、CalendarDimensions 和 TrailingForeColor 属性，以自定义日历控件的外观。设置其他属性（如 AnnuallyBoldedDates、BoldedDates 和 MonthlyBoldedDates）来自定义以粗体显示哪些日期。该示例还设置 FirstDayOfWeek、MaxDate、MinDate 和 MaxSelectionCount 属性，以更改日历格式。还处理了 DateSelected 和 DateChanged 事件并将它们的状态显示在窗体中。
