Question

我一直在尝试使用C＃将ListView控件的内容数据导出到Excel应用程序中。在使用VB.NET之前我已经完成了这个，我尝试将我的代码转换为C＃但是它失败但是我对它进行了修改，看起来下面的代码一切都很好，除了最后一部分将数据保存为excel文件。我需要帮助才能正确修改此代码。非常感谢您的回复。

下面出现错误的代码是：

oBook.SaveAs(SaveFileDialog1.InitialDirectory.ToString() + SaveFileDialog1.FileName);

错误5方法'SaveAs'没有重载需要'1'参数

private void Button4_Click(object sender, System.EventArgs e)
{
    int row = 0;
    int col = 0;
    int row2 = 0;
    int col2 = 0;
    int ch = 0;
    int ctr = 0;

    ctr = 0;
    row2 = 1;
    col2 = 3;

    row = 3;
    col = 3;

    Microsoft.Office.Interop.Excel.Application oExcel = new Microsoft.Office.Interop.Excel.Application();
    oExcel.Visible = false;
    Microsoft.Office.Interop.Excel.Workbook oBook = oExcel.Workbooks.Add(Microsoft.Office.Interop.Excel.XlSheetType.xlWorksheet);
    Microsoft.Office.Interop.Excel.Worksheet oSheet = (Microsoft.Office.Interop.Excel.Worksheet)oExcel.ActiveSheet;


    SaveFileDialog SaveFileDialog1 = new SaveFileDialog();
    SaveFileDialog1.Filter = "Excel File|*.xlsx|Word File|*.doc|Text File|*.txt";
    SaveFileDialog1.Title = "Save As";

    if (SaveFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
         switch (SaveFileDialog1.FilterIndex)
         {
            case 1:
            {
                for (ch = 1; ch <= ListView1.Columns.Count; ch++)
                {
                    oSheet.Cells[row2, col2] = ListView1.Columns[ctr].Text;

                    col2 = col2 + 1;
                    ctr = ctr + 1;
                }

                foreach (ListViewItem lview in ListView1.Items)
                {
                    foreach (ListViewItem.ListViewSubItem lview2 in lview.SubItems)
                    {
                        oSheet.Cells[row, col] = lview2.Text;
                        col = col + 1;
                    }

                    col = 3;
                    row = row + 1;
                }

                oBook.SaveAs(SaveFileDialog1.InitialDirectory.ToString() + SaveFileDialog1.FileName);
                oExcel.Quit();
                SaveFileDialog1.Dispose();
                MessageBox.Show("Data has been successfully saved", string.Empty, MessageBoxButtons.OK, MessageBoxIcon.Information);
                break;
            }
         }

工作簿SaveAs方法需要11个参数。在C＃中，即使您不关心它们，也必须为这些可选参数传递一些内容。最简单的方法是为那些你不关心的人传递System.Reflection.Missing.Value。但这很痛苦。
