使用 C# 设置 Excel 单元格值

Question

我使用以下代码来设置 Excel 文件的单元格值：

for (int i = 2; i < rowCount; i++)
{
    for (int j = 1; j < columnCount; j++)
    {
        worksheet.Cells[i, j].Value = enrollmentDataGrid.Columns[j].GetCellContent(enrollmentDataGrid.Items[i]);
    }
 }

但是我一直得到

错误：HRESULT 异常：0x800A03EC

为什么会出现此错误以及如何解决？

更新：

  try
            {

                saveFileDialog1.Title = "Save as Excel File";
                saveFileDialog1.FileName = "";
                saveFileDialog1.Filter = "Excel Files(2003)|*.xls|Excel Files(2007)|*.xls";
                if (saveFileDialog1.ShowDialog() != DialogResult.Cancel)
                {
                    Microsoft.Office.Interop.Excel.Application worksheet = new Microsoft.Office.Interop.Excel.Application();
                    worksheet.Application.Workbooks.Add(Type.Missing);
                    worksheet.Columns.ColumnWidth = 20;
                    for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
                    {
                        worksheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;

                    }
                    for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
                    {
                        for (int j = 0; j < dataGridView1.Columns.Count; j++)
                        {
                            worksheet.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
                        }

                    }
                    worksheet.ActiveWorkbook.SaveCopyAs(saveFileDialog1.FileName.ToString());
                    worksheet.ActiveWorkbook.Saved = true;
                    worksheet.Quit();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

Answer 2

我通常使用Value2 属性（不是Value）

因此，您的代码将如下所示：

for (int i = 2; i < rowCount; i++)
{
    for (int j = 1; j < columnCount; j++)
    {
        worksheet.Cells[i, j].Value2 = enrollmentDataGrid.Columns[j].GetCellContent(enrollmentDataGrid.Items[i]);
    }
 }

看来，你不是唯一一个： http://stackoverflow.com/questions/7099770/hresult-0x800a03ec-on-worksheet-range[^].

根据帖子，当您使用 在 Excel 2007 或 2010 中打开的旧 (xls) 工作簿。如果是这种情况， 在访问之前先尝试将文件另存为新格式的工作簿 细胞。

试试这个代码

for (int i = 1; i < columnCount + 1; i++)
                    {
                        worksheet.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;

                    }



 for (int i = 0; i < rowCount -1; i++)
    {
        for (int j = 0; j < columnCount; j++)
        {
            worksheet.Cells[i+2, j+1].Value2 = enrollmentDataGrid.Columns[j].GetCellContent(enrollmentDataGrid.Items[i]);
        }
     }

当我在 C# 中使用 wpf 框架编写导出到 xls 时。我也遇到了这个问题，我用下面的代码解决了。尝试从这段代码中查看

 Microsoft.Office.Interop.Excel._Application app = new Microsoft.Office.Interop.Excel.Application();
            Microsoft.Office.Interop.Excel._Workbook workbook = app.Workbooks.Add(Type.Missing);
            Microsoft.Office.Interop.Excel._Workbook workb = app.Workbooks.Open("c:\\Users\\Jack\\Documents\\Document1.xlsx", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
            Microsoft.Office.Interop.Excel._Worksheet worksheet = null;
            worksheet = workb.Sheets[1];
           // worksheet = workbook.Sheets[1];
            //worksheet = workbook.ActiveSheet;
            //worksheet.Name = "birinchi";




            for (int i = 0; i < Table.Columns.Count; i++) 
            {
             //   worksheet.Cells[1, i+1] = Table.Columns[i].Header;

            }


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

                    for (int j = 0; j < Table.Items.Count; j++)
                    {
                        TextBlock b = Table.Columns[i].GetCellContent(Table.Items[j]) as TextBlock;
                        worksheet.Cells[j + 2, i + 1] = b.Text;
                        //MessageBox.Show(b.Text);

                    }
                }

                Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
                dlg.FileName = "Document";
                dlg.DefaultExt = ".xlsx";
                Nullable<bool> result = dlg.ShowDialog();
                if (result == true)
                {

                   workbook.SaveAs(dlg.FileName, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);



                }
                app.Quit();
