EPPlus如何将Excel单元格格式检索到DataGridView中？

Question

如何使用EPPlus格式从保存的工作表从Excel加载到DatagridView？

将数据放入DatagridView。

private void importFastExcelCompare(DataGridView dt, string excelFileName,string sheetName)
{
    FileInfo fileInfo = new FileInfo(excelFileName);
    using (ExcelPackage xlPackage = new ExcelPackage(fileInfo))
    {    //create a list to hold all the values
        // get the first worksheet in the workbook
        ExcelWorksheet worksheet = xlPackage.Workbook.Worksheets[sName];
        // Fetch the WorkSheet size
        ExcelCellAddress startCell = worksheet.Dimension.Start;
        ExcelCellAddress endCell = worksheet.Dimension.End;

        for (Int32 row = startCell.Row; row <= endCell.Row; row++)
        {   // place all the data into DataTable
            dt.Rows.Add();
            for (int col = startCell.Column; col <= endCell.Column; col++)
            {
                var excelCell = worksheet.Workbook.Worksheets.First().Cells[row, col];
                var gridViewCell = dt.Rows[row - 1].Cells[col - 1];

               using (var range = excelCell.Worksheet.Cells[row, col, row, col])
                {
                   // gridViewCell.Style.ForeColor = range.Style.Font.Color;
                    //gridViewCell.Style.ForeColor = System.Drawing.Color.FromArgb(range.Style.Font.Color);
                }
                gridViewCell.Value = excelCell.Value;
            }
        }
    }

}

请帮忙。 谢谢。

Answer 1

EPPlus单元格具有样式属性。 例如，

worksheet.Cells["C2:C5"].Style.Numberformat.Format 

将为您提供单元格的数字格式。 同样，您可以访问以下属性以获取更多的单元格格式。

worksheet.Cells["C2:C5"].Style.Font
worksheet.Cells["C2:C5"].Style.Fill 
worksheet.Cells["C2:C5"].Style.Font.Color 

您可以查看https://github.com/JanKallman/EPPlus/wiki了解更多详细信息。

对我来说唯一有效的方法是分别评估字体设置。 不幸的是，加载将大大减慢速度。 也许有更好的解决方案....

 private void gridFont(ExcelRangeBase eFont, DataGridViewCell dtCell)
    {
        if (eFont.Style.Font.Bold && eFont.Style.Font.Italic && eFont.Style.Font.UnderLine)
        {
            System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Bold | FontStyle.Underline | FontStyle.Italic);
            dtCell.Style.Font = myFont;
        }
        else
        { 
        if (eFont.Style.Font.Bold && eFont.Style.Font.Italic)
        {
            System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Bold | FontStyle.Italic);
            dtCell.Style.Font = myFont;
        }
        else
            { 
        if (eFont.Style.Font.Bold && eFont.Style.Font.UnderLine)
        {
            System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Bold | FontStyle.Underline);
            dtCell.Style.Font = myFont;
        }
        else
           { 
        if (eFont.Style.Font.Italic && eFont.Style.Font.UnderLine)
        {
            System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Italic | FontStyle.Underline);
            dtCell.Style.Font = myFont;
        }
        else
          { 
                  if (eFont.Style.Font.Bold)
                     {

                        System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Bold);
                        dtCell.Style.Font = myFont;
                    }
                else
                        {
                            if (eFont.Style.Font.Italic)
                            {
                                System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Italic);
                                dtCell.Style.Font = myFont;
                            }
                            else
                            {
                                if (eFont.Style.Font.UnderLine)
                                {
                                    System.Drawing.Font myFont = new System.Drawing.Font(eFont.Style.Font.Name, eFont.Style.Font.Size, FontStyle.Underline);
                                    dtCell.Style.Font = myFont;
                                }

                            }

                        }

                    }
                }
            }
        }
     }
