在Excel文件中读取和写入多个程序访问

我的任务：

• 从网站获取数据并实时写入Excel文件（0.5 – 1s使用Microsoft.Office.Interop.Excel）

• 当程序写入数据到Excel文件时，我想打开这个文件（Excel或类似的东西）来查看数据，图表…

那么如何在同一时间读写Excel文件呢？ 或者我可以用另一种方式吗？

void ExportToExcel（）{

  try { SaveFileDialog svg = new SaveFileDialog(); using (FileStream stream = new FileStream(svg.FileName + ".xlsx", FileMode.Create)) { Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application(); excel.Visible = true; Microsoft.Office.Interop.Excel.Workbook workbook = excel.Workbooks.Add(System.Reflection.Missing.Value); Microsoft.Office.Interop.Excel.Worksheet sheet1 = (Microsoft.Office.Interop.Excel.Worksheet)workbook.Sheets[1]; int StartCol = 1; int StartRow = 1; int j = 0, i = 0; //Write Headers for (j = 0; j < dataGridView1.Columns.Count; j++) { Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)sheet1.Cells[StartRow, StartCol + j]; myRange.Value2 = dataGridView1.Columns[j].HeaderText; } StartRow++; //Write datagridview content for (i = 0; i < dataGridView1.Rows.Count; i++) { for (j = 0; j < dataGridView1.Columns.Count; j++) { try { Microsoft.Office.Interop.Excel.Range myRange = (Microsoft.Office.Interop.Excel.Range)sheet1.Cells[StartRow + i, StartCol + j]; myRange.Value2 = dataGridView1[j, i].Value == null ? "" : dataGridView1[j, i].Value.ToString(); } catch { ; } } } } } catch (Exception ex) { MessageBox.Show(ex.ToString()); } }
