GemBox.ExcelLite.dll导出到Excel

利用GemBox.ExcelLite.dll脱离Excel环境,把DataGridView数据导出到Excel文件。

public void DataGridView2Excel_GemBox(DataGridView dgv)
        {
            #region 导出前判断
            //行数必须大于0
            if (dgv.Rows.Count <= 0)
            {
                MessageBox.Show("没有数据可供导出!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
                return;
            }
            //列数必须大于0
            if(dgv.Columns.Count<=0)
            {
                MessageBox.Show("没有数据可供导出!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
                return;
            }
            //行数不可以大于65536
            if(dgv.Rows.Count>65536)
            {
                MessageBox.Show("数据记录数太多(最多不能超过65536条),不能保存!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
                return;
            }
            //列数不可以大于256
            if(dgv.Columns.Count>256)
            {
                MessageBox.Show("数据记录数太多(最多不能超过256列),不能保存!","提示",MessageBoxButtons.OK,MessageBoxIcon.Information);
                return;
            }
            #endregion
            SaveFileDialog dlg = new SaveFileDialog();
            dlg.Filter = "Excel files (*.xls)|*.xls";
            dlg.FilterIndex = 0;
            dlg.RestoreDirectory = true;
            dlg.CreatePrompt = false;
            dlg.Title = "导出为Excel文件";

            {
                ExcelFile excelFile = new ExcelFile();
                ExcelWorksheet sheet = excelFile.Worksheets.Add("Account");
                try
                {
                    //向Excel中写入表格的表头
                    for (int i = 0; i < dgv.Columns.Count; i++)
                    {
                        sheet.Cells[0, i].Value = dgv.Columns[i].HeaderText;
                    }
                    //向Excel中写入表格的数据
                    for (int i = 0; i < dgv.Rows.Count; i++)
                    {
                        DataGridViewRow row = dgv.Rows[i];
                        for (int j = 0; j < row.Cells.Count; j++)
                        {
                            sheet.Cells[i + 1, j].Value = row.Cells[j].Value;
                        }
                    }
                    excelFile.SaveXls(dlg.FileName);
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message, "警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                    return;
                }
                MessageBox.Show(dlg.FileName + "\n\n导出完毕!", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
