注解
如果需要自动重新分页来响应事件（例如更改的页面大小 FlowDocument ），请使用 DynamicDocumentPaginator 作为基类。If you need automatic background repagination in response to events such as changing the page size of a FlowDocument, then use DynamicDocumentPaginator as your base class.
构造函数
| DocumentPaginator() |
初始化 DocumentPaginator 类的新实例。Initializes a new instance of the DocumentPaginator class. |
属性
| IsPageCountValid |
当在派生类中重写时，获取一个指示 PageCount 是否为总页数的值。When overridden in a derived class, gets a value indicating whether PageCount is the total number of pages. |
| PageCount |
当在派生类中重写时，获取当前已设置格式的页数的计数。When overridden in a derived class, gets a count of the number of pages currently formatted. |
| PageSize |
在派生类中重写时，获取或设置每一页的建议宽度和高度。When overridden in a derived class, gets or sets the suggested width and height of each page. |
| Source |
在派生类中重写时，返回正在进行分页的元素。When overridden in a derived class, returns the element being paginated. |
方法
| CancelAsync(Object) |
取消前一个 GetPageAsync 或 GetPageNumberAsync 操作。Cancels a previous GetPageAsync or GetPageNumberAsync operation. |
| ComputePageCount() |
强制对内容进行分页，用新的总页数更新 PageCount，并将 IsPageCountValid 设置为 |
| ComputePageCountAsync() |
通过异步方式强制对内容进行分页，用新的总页数更新 PageCount，并将 IsPageCountValid 设置为 |
| ComputePageCountAsync(Object) |
通过异步方式强制对内容进行分页，用新的总页数更新 PageCount，并将 IsPageCountValid 设置为 |
| Equals(Object) |
确定指定对象是否等于当前对象。Determines whether the specified object is equal to the current object. (继承自 Object) |
| GetHashCode() |
作为默认哈希函数。Serves as the default hash function. (继承自 Object) |
| GetPage(Int32) |
当在派生类中重写时，获取指定页码的 DocumentPage。When overridden in a derived class, gets the DocumentPage for the specified page number. |
| GetPageAsync(Int32) |
（通过 GetPageCompleted 事件）异步返回指定页码的 DocumentPage。Asynchronously returns (through the GetPageCompleted event) the DocumentPage for the specified page number. |
| GetPageAsync(Int32, Object) |
（通过 GetPageCompleted 事件）异步返回指定页码的 DocumentPage，并将指定的 ID 分配给异步任务。Asynchronously returns (through the GetPageCompleted event) the DocumentPage for the specified page number and assigns the specified ID to the asynchronous task. |
| GetType() |
获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object) |
| MemberwiseClone() |
创建当前 Object 的浅表副本。Creates a shallow copy of the current Object. (继承自 Object) |
| OnComputePageCountCompleted(AsyncCompletedEventArgs) |
引发 ComputePageCountCompleted 事件。Raises the ComputePageCountCompleted event. |
| OnGetPageCompleted(GetPageCompletedEventArgs) |
引发 GetPageCompleted 事件。Raises the GetPageCompleted event. |
| OnPagesChanged(PagesChangedEventArgs) |
引发 PagesChanged 事件。Raises the PagesChanged event. |
| ToString() |
返回表示当前对象的字符串。Returns a string that represents the current object. (继承自 Object) |
事件
| ComputePageCountCompleted |
ComputePageCountAsync 操作完成时发生。Occurs when a ComputePageCountAsync operation has finished. |
| GetPageCompleted |
在 GetPageAsync 完成时发生。Occurs when GetPageAsync has completed. |
| PagesChanged |
在文档内容改变时发生。Occurs when the document content is changed. |
