我看了很多例子和演示，但我看不到

我正在尝试将datagridview转换为excel。

我的结果https://i.stack.imgur.com/x6WlF.png

但它变成了这样的优秀https://i.stack.imgur.com/3iK5a.png

我想复制单元格的大小和颜色，但如何复制？

我用这个代码转换成excel

        Excel.Application xlApp;
        Excel.Workbook xlWorkBook;
        Excel.Worksheet xlWorkSheet;
        object misValue = System.Reflection.Missing.Value;
        Int16 i, j;
        xlApp = new Excel.Application();
        xlWorkBook = xlApp.Workbooks.Add(misValue);
        xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
        for (i = 0; i <= dataGridView1.RowCount - 2; i++)
        {
            for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)
            {
                xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1[j, i].Value.ToString();
            }
        }
        SaveFileDialog sfd = new SaveFileDialog();
        sfd.Filter = "Excel Documents (*.xls)|*.xls";
        sfd.FileName = listBox1.SelectedItem.ToString() + " " + listBox3.SelectedItem.ToString() + " Stok Reçeteleri" + ".xls";

        if (sfd.ShowDialog() == DialogResult.OK)
        {
            //ToCsV(dataGridView1, sfd.FileName); // Here dataGridview1 is your grid view name
            xlWorkBook.SaveAs(sfd.FileName, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
            //xlWorkBook.SaveAs(sfd.FileName, Excel.XlFileFormat.X
            FileInfo fileInfo = new FileInfo(sfd.FileName);
        }

        xlWorkBook.Close(true, misValue, misValue);
        xlApp.Quit();
        releaseObject(xlWorkSheet);
        releaseObject(xlWorkBook);
        releaseObject(xlApp);

带彩色单元格的DataGridView到Excel

将内部循环更新为：

for (i = 0; i <= dataGridView1.RowCount - 2; i++)
            {
                for (j = 0; j <= dataGridView1.ColumnCount - 1; j++)
                {
                    Range range = (Range)xlWorkSheet.Cells[i + 1, j + 1];
                    xlWorkSheet.Cells[i + 1, j + 1] = dataGridView1[j, i].Value.ToString();
                    range.Interior.Color = System.Drawing.ColorTranslator.ToOle(dataGridView1.Rows[i].DefaultCellStyle.BackColor );
                }
            }

别忘了：

using Microsoft.Office.Interop.Excel;

使用C#更改Cells的背景

尝试使用此代码导出到excel，而不是您正在使用的代码。不过，我在网络应用程序中使用了这个。

private void ExportGridToExcel()
{
    Response.Clear();
    Response.Buffer = true;
    Response.ClearContent();
    Response.ClearHeaders();
    Response.Charset = "";
    string FileName = "SomeFileName" + DateTime.Now + ".xls";
    StringWriter strwritter = new StringWriter();
    HtmlTextWriter htmltextwrtter = new HtmlTextWriter(strwritter);
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.ContentType = "application/vnd.ms-excel";
    Response.AddHeader("Content-Disposition", "attachment;filename=" + FileName);
    GridView1.GridLines = GridLines.Both;
    GridView1.HeaderStyle.Font.Bold = true;
    GridView1.RenderControl(htmltextwrtter);
    Response.Write(strwritter.ToString());
    Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
    /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
       server control at run time. */
}
