HelpProvider.HelpNamespace 属性
定义
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
获取或设置一个值，该值指定与此 HelpProvider 对象关联的帮助文件名。
public:
virtual property System::String ^ HelpNamespace { System::String ^ get(); void set(System::String ^ value); };public virtual string HelpNamespace { get; set; }public virtual string? HelpNamespace { get; set; }member this.HelpNamespace : string with get, setPublic Overridable Property HelpNamespace As String属性值
帮助文件的名称。 其形式可以是 C:\path\sample.chm 或 /folder/file.htm。
示例
以下示例演示如何使用 HelpProvider 类在包含四个地址字段的窗体上显示上下文相关的帮助。 该示例使用 SetHelpString 设置帮助工具提示文本。 使用上下文相关的“帮助”按钮并单击地址字段上的“帮助”光标时，“帮助工具提示”将显示指定文本。 在地址字段中按具有焦点的 F1 键时， mspaint.chm 将显示帮助文件， HelpNamespace 因为 属性已设置为 mspaint.chm。 SetShowHelp为每个地址控件调用 方法，以标识其是否有可用的帮助内容。
