如何将dataGridView数据立即导出到Excel按钮上单击?

我在数据网格视图中有10k行和15列。 我想将这些数据导出到excel表单按钮单击。 我已经尝试使用下面的代码。

private void btExport_Click(object sender, EventArgs e)
    {
        Microsoft.Office.Interop.Excel._Application app  = new Microsoft.Office.Interop.Excel.Application();
        Microsoft.Office.Interop.Excel._Workbook workbook =  app.Workbooks.Add(Type.Missing);        
        Microsoft.Office.Interop.Excel._Worksheet worksheet = null;                   
        app.Visible = true;
        worksheet = workbook.Sheets["Sheet1"];
        worksheet = workbook.ActiveSheet;                  
        for(int i=1;i<dataGridView1.Columns.Count+1;i++)
        {
             worksheet.Cells[1, i] = dataGridView1.Columns[i-1].HeaderText;
        }    
        for (int i=0; i < dataGridView1.Rows.Count-1 ; i++)
        {
            for(int j=0;j<dataGridView1.Columns.Count;j++)
            {
                if (dataGridView1.Rows[i].Cells[j].Value != null)
                {
                    worksheet.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
                }
                else
                {
                    worksheet.Cells[i + 2, j + 1] = "";
                }
            }
        }
    }

这对我很有用,要花费很多时间才能完成出口流程。

是否有可能从dataGridView(具有10k行)导出到按钮单击时立即擅长?

除此之外,当我尝试将所有dataGridview内容复制到剪贴板,然后手动将其粘贴到Excel表格中时,它几乎立即发生。

那么有没有办法将所有dataGridView单元复制到剪贴板,然后通过点击按钮将其粘贴到Excel表格(使用单元格格式)?

我有如下复制到剪贴板的代码,但我不知道如何通过打开它将其粘贴到新的Excel表单中。

        private void copyAllToolStripMenuItem_Click(object sender, EventArgs e)
    {
        dataGridView1.SelectAll();
        DataObject dataObj = dataGridView1.GetClipboardContent();
        if (dataObj != null)
            Clipboard.SetDataObject(dataObj);
    }

请帮助一个例子。 我是C#的新手。


我用简单的复制和粘贴方法解决了这个问题。 我不知道这是做到这一点的最佳方式,但对我而言,它运作良好,几乎是即时的。 这是我的代码。

    private void copyAlltoClipboard()
    {
        dataGridView1.SelectAll();
        DataObject dataObj = dataGridView1.GetClipboardContent();
        if (dataObj != null)
            Clipboard.SetDataObject(dataObj);
    }
    private void button3_Click_1(object sender, EventArgs e)
    {
        copyAlltoClipboard();
        Microsoft.Office.Interop.Excel.Application xlexcel;
        Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
        Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;
        xlexcel = new Excel.Application();
        xlexcel.Visible = true;
        xlWorkBook = xlexcel.Workbooks.Add(misValue);
        xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        Excel.Range CR = (Excel.Range)xlWorkSheet.Cells[1, 1];
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);          
    }

谢谢。


这是一个很好的问题,我很惊讶于找到一个清晰完整的答案有多困难,我发现的大部分答案都是sudo-code或不完整。

我能够创建一个完整的解决方案,基于Jake的答案创建一个完整的解决方案,将我的DataGridView中的数据复制并保存到一个excel文件中,因此我发布了完整的解决方案,希望它能帮助其他新手入手,例如我自己:)

首先,您需要在您的项目中使用Microsoft.Office.Interop.Excel参考。 有关如何添加它的信息,请参阅MSDN。

我的代码:

using Excel = Microsoft.Office.Interop.Excel;

private void btnExportToExcel_Click(object sender, EventArgs e)
{
    SaveFileDialog sfd = new SaveFileDialog();
    sfd.Filter = "Excel Documents (*.xls)|*.xls";
    sfd.FileName = "Inventory_Adjustment_Export.xls";
    if (sfd.ShowDialog() == DialogResult.OK)
    {
        // Copy DataGridView results to clipboard
        copyAlltoClipboard();

        object misValue = System.Reflection.Missing.Value;
        Excel.Application xlexcel = new Excel.Application();

        xlexcel.DisplayAlerts = false; // Without this you will get two confirm overwrite prompts
        Excel.Workbook xlWorkBook = xlexcel.Workbooks.Add(misValue);
        Excel.Worksheet xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

        // Format column D as text before pasting results, this was required for my data
        Excel.Range rng = xlWorkSheet.get_Range("D:D").Cells;
        rng.NumberFormat = "@";

        // Paste clipboard results to worksheet range
        Excel.Range CR = (Excel.Range)xlWorkSheet.Cells[1, 1];
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);

        // For some reason column A is always blank in the worksheet. ¯_(ツ)_/¯
        // Delete blank column A and select cell A1
        Excel.Range delRng = xlWorkSheet.get_Range("A:A").Cells;
        delRng.Delete(Type.Missing);
        xlWorkSheet.get_Range("A1").Select();

        // Save the excel file under the captured location from the SaveFileDialog
        xlWorkBook.SaveAs(sfd.FileName, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
        xlexcel.DisplayAlerts = true;
        xlWorkBook.Close(true, misValue, misValue);
        xlexcel.Quit();

        releaseObject(xlWorkSheet);
        releaseObject(xlWorkBook);
        releaseObject(xlexcel);

        // Clear Clipboard and DataGridView selection
        Clipboard.Clear();
        dgvItems.ClearSelection();

        // Open the newly saved excel file
        if (File.Exists(sfd.FileName))
            System.Diagnostics.Process.Start(sfd.FileName);
    }
}

private void copyAlltoClipboard()
{
    dgvItems.SelectAll();
    DataObject dataObj = dgvItems.GetClipboardContent();
    if (dataObj != null)
        Clipboard.SetDataObject(dataObj);
}

private void releaseObject(object obj)
{
    try
    {
        System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
        obj = null;
    }
    catch (Exception ex)
    {
        obj = null;
        MessageBox.Show("Exception Occurred while releasing object " + ex.ToString());
    }
    finally
    {
        GC.Collect();
    }
}

我不打算偷@Jake和@ Cornelius的答案,所以我试着编辑它。 但被拒绝了。 无论如何,我必须指出的唯一改进就是在粘贴后避免在excel中出现多余的空白列。 添加一行dataGridView1.RowHeadersVisible = false; 隐藏所谓的“行标题”,它出现在DataGridView的最左边部分,因此当您执行dataGridView1.SelectAll();时,它不会被选中并复制到剪贴板dataGridView1.SelectAll();

private void copyAlltoClipboard()
    {
        //to remove the first blank column from datagridview
        dataGridView1.RowHeadersVisible = false;
        dataGridView1.SelectAll();
        DataObject dataObj = dataGridView1.GetClipboardContent();
        if (dataObj != null)
            Clipboard.SetDataObject(dataObj);
    }
    private void button3_Click_1(object sender, EventArgs e)
    {
        copyAlltoClipboard();
        Microsoft.Office.Interop.Excel.Application xlexcel;
        Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
        Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;
        xlexcel = new Excel.Application();
        xlexcel.Visible = true;
        xlWorkBook = xlexcel.Workbooks.Add(misValue);
        xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        Excel.Range CR = (Excel.Range)xlWorkSheet.Cells[1, 1];
        CR.Select();
        xlWorkSheet.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);          
    }
