如何将参数从c发送到excel并保存在那里

本文关键字:excel 保存 在那里 参数 | 更新日期: 2023-09-27 18:21:10

我有两个问题,我正面临

  • 我有一个数据集,需要将数据从数据集发送到excel一旦将数据转储到该位置。

  • 我需要更改列标题,使其加粗

2:在报告标题上方,我们应该传递一个参数,该参数将是我们需要作为参数传递给它的c#中的名称(员工详细信息)。它可以改变我们传递的任何参数。

例如:报告名称:员工详细信息

  Name      EmpID   city
  Arun        11       bangalore
  Kiran       56       chennai
  Rahul       23       pune

如何将参数从c发送到excel并保存在那里

下面的应该可以工作,但我没有测试它。感谢Deborah Kurata编写了下面的大部分代码。

using Excel = Microsoft.Office.Interop.Excel;
using System.Reflection;
private void ExportToExcel(DataTable Table, string ReportName, string Filename)
{
  Excel.Application oXL;
  Excel.Workbook oWB;
  Excel.Worksheet oSheet;
  Excel.Range oRange;
  // Start Excel and get Application object.
  oXL = new Excel.Application();
  // Set some properties
  oXL.Visible = true;
  oXL.DisplayAlerts = false;
  // Get a new workbook.
  oWB = oXL.Workbooks.Add(Missing.Value);
  // Get the active sheet
  oSheet = (Excel.Worksheet)oWB.ActiveSheet ;
  oSheet.Name = "Report";
  int rowCount = 3;
  foreach (DataRow dr in Table.Rows)
  {
      for (int i = 1; i < Table.Columns.Count+1; i++)
      {
          // Add the header the first time through
          if (rowCount==3)
          {
              oSheet.Cells[1, i] = Table.Columns[i - 1].ColumnName;
              rowCount++;
          }
          oSheet.Cells[rowCount, i] = dr[i - 1].ToString();
      }
      rowCount++;
  }
  // Resize the columns
  oRange = oSheet.get_Range(oSheet.Cells[3, 1],
                oSheet.Cells[rowCount, Table.Columns.Count]);
  oRange.EntireColumn.AutoFit();
  // Set report title *after* we adjust column widths
  oSheet.Cells[1,1] = ReportName;
  // Save the sheet and close
  oSheet = null;
  oRange = null;
  oWB.SaveAs(Filename, Excel.XlFileFormat.xlWorkbookNormal,
      Missing.Value, Missing.Value, Missing.Value, Missing.Value,
      Excel.XlSaveAsAccessMode.xlExclusive,
      Missing.Value, Missing.Value, Missing.Value,
      Missing.Value, Missing.Value);
  oWB.Close(Missing.Value, Missing.Value, Missing.Value);
  oWB = null;
  oXL.Quit();
  // Clean up
  // NOTE: When in release mode, this does the trick
  GC.WaitForPendingFinalizers();
  GC.Collect();
  GC.WaitForPendingFinalizers();
  GC.Collect();
