定義

擷取格式化的值,該值表示要複製到 Clipboard 之選定儲存格的內容。

public:
 virtual System::Windows::Forms::DataObject ^ GetClipboardContent();
public virtual System.Windows.Forms.DataObject GetClipboardContent ();
public virtual System.Windows.Forms.DataObject? GetClipboardContent ();
abstract member GetClipboardContent : unit -> System.Windows.Forms.DataObject
override this.GetClipboardContent : unit -> System.Windows.Forms.DataObject
Public Overridable Function GetClipboardContent () As DataObject

傳回

DataObject,表示選定儲存格的內容。

範例

下列程式碼範例示範如何以程式設計方式將選取 DataGridView 的內容新增至剪貼簿。 此範例是 How to: Enable Users to Copy Multiple Cells to the Clipboard from the Windows Forms DataGridView Control中較大型範例的一部分。

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"})
    Me.DataGridView1.Rows.Add(New String() {"F", "G", "H", "I", "J"})
    Me.DataGridView1.Rows.Add(New String() {"K", "L", "M", "N", "O"})
    Me.DataGridView1.Rows.Add(New String() {"P", "Q", "R", "S", "T"})
    Me.DataGridView1.Rows.Add(New String() {"U", "V", "W", "X", "Y"})
    Me.DataGridView1.AutoResizeColumns()
    Me.DataGridView1.ClipboardCopyMode = _
        DataGridViewClipboardCopyMode.EnableWithoutHeaderText

End Sub

Private Sub CopyPasteButton_Click(ByVal sender As Object, _
    ByVal e As System.EventArgs) Handles CopyPasteButton.Click

    If Me.DataGridView1.GetCellCount( _
        DataGridViewElementStates.Selected) > 0 Then

        Try

            ' Add the selection to the clipboard.
            Clipboard.SetDataObject( _
                Me.DataGridView1.GetClipboardContent())

            ' Replace the text box contents with the clipboard text.
            Me.TextBox1.Text = Clipboard.GetText()

        Catch ex As System.Runtime.InteropServices.ExternalException
            Me.TextBox1.Text = _
                "The Clipboard could not be accessed. Please try again."
        End Try

    End If

End Sub

備註

這個方法會擷取代表所選取儲存格所定義之區域的資料。 此區域是包含所有選取儲存格的最小矩形。 呼叫 方法會擷 DataGridViewCell.GetClipboardContent 取此區域中每個選取儲存格的值。 空白預留位置值會用於此區域中未選取的儲存格。 這個方法會將這些值結合成 DataObject 包含數種格式的 ,以複製到剪貼簿。 支援的剪貼簿格式包括 DataFormats.TextDataFormats.UnicodeTextDataFormats.HtmlDataFormats.CommaSeparatedValue

如需詳細資訊,請參閱 Clipboard 類別。

給繼承者的注意事項

覆寫這個方法以提供自訂的剪貼簿值。 例如,若要支援從自訂資料格類型複製值,這非常有用。
