我有这个代码从dataSet转移到Excel(xlsx)
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Excel;
string SQL = "SELECT Store,Zitur FROM CounterG group by Store,Zitur";
var dsView = new DataSet();
using (var adp = new OleDbDataAdapter(SQL, Conn))
adp.Fill(dsView, "CounterG");
Microsoft.Office.Interop.Excel.Application xla = new Microsoft.Office.Interop.Excel.Application();
xla.Visible = false;
Workbook wb = xla.Workbooks.Add(XlSheetType.xlWorksheet);
Worksheet ws = (Worksheet)xla.ActiveSheet;
ws.Name = "Tab1";
int i = 1;
foreach (DataRow comp in dsView.Tables[0].Rows)
{
ws.Cells[i, 1] = comp[0].ToString();
ws.Cells[i, 2] = comp[1].ToString();
i++;
}
if (File.Exists(@"d\DDD.xlsx"))
File.Delete(@"d:\DDD.xlsx");
//xla.SaveWorkspace(@"d:\DDD.xlsx");
xla.Save(@"d:\DDD.xlsx");
但是我从HRESULT得到了错误" 异常:0x800A03EC "在这一行:xla.Save(@"d:\DDD.xlsx");
我使用.NET Framework 2.0处理WinForm。
答案 0 :(得分:0)
请尝试使用Workbook.SaveAs,如下所示。您还需要包含Excel.Quit()来释放文件。
//xla.SaveWorkspace(@"d:\DDD.xlsx");
wb.SaveAs(Filename: @"d:\DDD.xlsx", FileFormat: XlFileFormat.xlOpenXMLWorkbook);
xla.Quit(); // Exit Excel releasing the file
根据文档,您不应使用Excel.Application.Save来创建文件:
首次保存工作簿时,请使用 Microsoft.Office.Interop.Excel._Workbook.SaveAs() 指定文件名称的方法。
