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

            dlg.FilterIndex

            dlg.RestoreDirectory

            dlg.CreatePrompt

            dlg.Title

if (dlg.ShowDialog() == DialogResult.OK)
            {
                ExcelFile excelFile 
= new ExcelFile();
                ExcelWorksheet sheet 
= excelFile.Worksheets.Add("Account");
                
try
                {

                    for (int i = 0; i < dgv.Columns.Count; i++)

                        {
                            sheet.Cells[i

                        }
                    }
                    excelFile.SaveXls(dlg.FileName);
                }
                
catch (Exception ex)
                {
                    MessageBox.Show(ex.Message, 
"警告", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                    
return;
                }
                MessageBox.Show(dlg.FileName
