示例
下面的代码示例演示如何在控件中 DataGridView 启用复制。 有关完整示例，请参阅如何：让用户从 Windows 窗体 DataGridView 控件将多个单元格复制到剪贴板。
private void Form1_Load(object sender, System.EventArgs e)
{
// Initialize the DataGridView control.
this.DataGridView1.ColumnCount = 5;
this.DataGridView1.Rows.Add(new string[] { "A", "B", "C", "D", "E" });
this.DataGridView1.Rows.Add(new string[] { "F", "G", "H", "I", "J" });
this.DataGridView1.Rows.Add(new string[] { "K", "L", "M", "N", "O" });
this.DataGridView1.Rows.Add(new string[] { "P", "Q", "R", "S", "T" });
this.DataGridView1.Rows.Add(new string[] { "U", "V", "W", "X", "Y" });
this.DataGridView1.AutoResizeColumns();
this.DataGridView1.ClipboardCopyMode =
DataGridViewClipboardCopyMode.EnableWithoutHeaderText;
}
private void CopyPasteButton_Click(object sender, System.EventArgs e)
{
if (this.DataGridView1
.GetCellCount(DataGridViewElementStates.Selected) > 0)
{
try
{
// Add the selection to the clipboard.
Clipboard.SetDataObject(
this.DataGridView1.GetClipboardContent());
// Replace the text box contents with the clipboard text.
this.TextBox1.Text = Clipboard.GetText();
}
catch (System.Runtime.InteropServices.ExternalException)
{
this.TextBox1.Text =
"The Clipboard could not be accessed. Please try again.";
}
}
}
Private Sub Form1_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles Me.Load
' Initialize the DataGridView control.
Me.DataGridView1.ColumnCount = 5
Me.DataGridView1.Rows.Add(New String() {"A", "B", "C", "D", "E"})
