如何在WPF中获取剪贴板内容 [英] How to get the clipboard content in WPF

问题描述

我正在编写一个应用程序，当用户在Datagrid中选择行并按Ctrl C时，它必须获取剪贴板内容.按Ctrl V时必须粘贴.

我将模式设置为

Hi,

I am writing an application in which when user select rows in Datagrid and press Ctrl C, it has to get the clip board content. When Ctrl V is pressed it has to paste.

I am setting mode as

myDataGrid.ClipBoardCopyMode = Windows.Controls.DataGridCopyMode.ExcludeHeader

之后，我要获取剪贴板内容，如我们使用的Windows窗体中的

myDataGridView.GetClipboardContent()方法获取内容.


WPF中是否有类似于Windows Form的GetClipboardContent()的方法.


感谢任何建议，

Vijay

after this I want to get the clipboard content as in the windows form where we use

myDataGridView.GetClipboardContent() method to get the content.


Is there any method in WPF similar to GetClipboardContent() of Windows Form.


Appreciate any suggestions,

Vijay

推荐答案

您需要使用以下命令: http://msdn.microsoft.com/en-us/library/system.windows. dataformats.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system. windows.dataformats.serializable.aspx [ ^ ].

此格式的使用基于使用实现接口IDataObject的类DataObject的假设:
http://msdn.microsoft.com/en-us/library/system.windows. dataobject.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. idataobject.aspx [ ^ ].

它的背景非常简单有趣.由于剪贴板的底层是一些序列化的原始字节数据(否则，剪贴板是系统范围的)，因此该机制基于串行化:
http://en.wikipedia.org/wiki/Serialization [ http://en.wikipedia.org/wiki/Serialization#.NET_Framework [ http://msdn.microsoft.com/en-us/library/vstudio/ms233843.aspx [ ^ ].

自定义剪贴板类型是用一些字符串 atom 注册的，该字符串在系统范围内是唯一的，应通过将数据放入剪贴板并读取的代码来识别.不论哪种类型，两个部分都使用相同的序列化机制就足够了.一旦代码部分共享相同的机制，一切就可以工作.对于不使用此自定义类型的应用程序，这是一些无法识别的格式，因此未订阅.

You need to use this: http://msdn.microsoft.com/en-us/library/system.windows.clipboard.aspx[^].

The method you want is GetData or GetDataObject.

Probably, your problem is working with the custom data format. In this clipboard class, this functionality is predefined via the special data format expressed by means of the class DataFormats and its public field DataFormats.Serializable:
http://msdn.microsoft.com/en-us/library/system.windows.dataformats.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.dataformats.serializable.aspx[^].

The use of this format is based on the assumption of using the class DataObject implementing the interface IDataObject:
http://msdn.microsoft.com/en-us/library/system.windows.dataobject.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.idataobject.aspx[^].

The background of it is pretty simple and interesting. As the low-level of the Clipboard is some serialized raw byte data (how else? Clipboard is system-wide), the mechanism is based on serialization:
http://en.wikipedia.org/wiki/Serialization[^],
http://en.wikipedia.org/wiki/Serialization#.NET_Framework[^].
http://msdn.microsoft.com/en-us/library/vstudio/ms233843.aspx[^].

Custom Clipboard types are registered with some string atom, unique in the scope of system which should be recognized by the code putting data in Clipboard and reading it. It''s enough that both parts used identical serialization mechanism, not matter what kind. As soon as those to parts of code share the same mechanism, everything works; and for the applications not involved in using this custom type, this is some unrecognized format they are not subscribed to.

要将DataGrid内容获取到剪贴板，我们应该使用Clipboard GetData方法.

下面的示例演示如何将DataGrid的所有单元格"myDataGrid"复制到文本框.
当复制模式选择为IncludeHeader时，它将复制DatGrid的ColumnName.

To get the DataGrid content to clipboard we should use the Clipboard GetData method.

Below example shows how to copy All the cells of DataGrid "myDataGrid" to textbox.
It will copy the ColumnName of DatGrid as IncludeHeader is selected for copy mode.

Me.myDataGrid.SelectAllCells()
Me.myDataGrid.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader
ApplicationCommands.Copy.Execute(Nothing, Me.myDataGrid)
Dim tempString as String = Clipboard.GetData(DataFormats.CommaSeperatedValue)

Me.myTextBox.text = tempString
