如何：使用户能够将多个单元格从 Windows 窗体 DataGridView 控件复制到剪贴板
更新：2007 年 11 月
启用单元格复制时，其他应用程序将能够很容易地通过 Clipboard 访问 DataGridView 控件中的数据。选择的单元格的值会转换为字符串，并作为以制表符分隔的文本值添加到剪贴板中，以便粘贴到类似记事本和 Excel 的应用程序中；或作为 HTML 格式的表添加到剪贴板中，以便粘贴到类似 Word 的应用程序中。
您可以将单元格复制配置为：仅复制单元格值，在剪贴板数据中包含行标头和列标头的文本，或者在用户选择整行或整列时仅包含标头文本。
根据选择模式的不同，用户可选择多个不连续的单元格组。当用户将单元格复制到剪贴板时，不会复制未选择其中的单元格的行和列。所有其他行或列都将成为复制到剪贴板中的数据表中的行和列。这些行或列中未选择的单元格会作为空白占位符复制到剪贴板中。
启用单元格复制
设置 DataGridView.ClipboardCopyMode 属性。
Me.DataGridView1.ClipboardCopyMode = _ DataGridViewClipboardCopyMode.EnableWithoutHeaderTextthis.DataGridView1.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableWithoutHeaderText;
示例
下面的完整代码示例演示如何将单元格复制到剪贴板中。此示例包含一个按钮，该按钮使用 DataGridView.GetClipboardContent 方法将选择的单元格复制到剪贴板中，并在文本框中显示剪贴板内容。
