DocumentList 类

表示以一致的方式显示和管理文档的 Pocket PC 控件。

命名空间：  Microsoft.WindowsCE.Forms
程序集：  Microsoft.WindowsCE.Forms（在 Microsoft.WindowsCE.Forms.dll 中）

语法

声明
Public Class DocumentList _
    Inherits Control
用法
Dim instance As DocumentList

public class DocumentList : Control

public ref class DocumentList : public Control

public class DocumentList extends Control

备注

DocumentList 控件提供本机 Windows CE DocList 控件的托管实现，此控件在某些情况下（例如，在启动 Microsoft® Pocket Word 和 Microsoft® Pocket Excel 时）是可见的。此控件提供以下功能：

• 选择、删除、复制、移动和重命名文件和文件夹。

• 按文件名、日期或大小排序。

• 以电子邮件方式发送文件。

• 通过红外装置将文件发送到其他设备。

DocumentList 是一个控件，而不是一个完整的类似于 FileDialog 的对话框。利用 DocumentList 控件，您可以在您的文件选择 UI 中加入自定义菜单或其他控件。

DocumentList 的宽度应与它所在的表单相同。长度可根据需要来决定。

DocumentList 仅显示“我的文档”层次结构中的所选文件夹的文件。
