C# 导出为 PDF 并仅添加列，不包含按钮

Question

我制作了一个密码管理器应用程序。我试图只导出名称、用户名、密码和更改日期行。但现在，它还会导出列按钮。

有什么提示吗？

当我使用此代码导出时：

  private void exportToPDFToolStripMenuItem_Click(object sender, EventArgs e)
    {
        SaveFileDialog sfd = new SaveFileDialog();
        sfd.Filter = "Pdf File |*.pdf";
        if (sfd.ShowDialog() == DialogResult.OK)
        {
            Document doc = new Document(iTextSharp.text.PageSize.LETTER, 10, 10, 42, 35);
            PdfWriter wri = PdfWriter.GetInstance(doc, new FileStream(sfd.FileName, FileMode.Create));
            doc.Open();//Open Document to write

            Paragraph paragraph = new Paragraph("data Exported From PassVault!\n\n");
            PdfPTable table = new PdfPTable(dgvPasswords.Columns.Count);

            //Add the headers
            for (int j = 0; j < dgvPasswords.Columns.Count; j++)
            {
                table.AddCell(new Phrase(dgvPasswords.Columns[j].HeaderText));

            }

            //Flag the first row as header
            table.HeaderRows = 1;

            //Add the actual rows from the DGV to the table
            for (int i = 0; i < dgvPasswords.Columns.Count; i++)
            {
                for (int k = 0; k < dgvPasswords.Rows.Count; k++)
                {
                    if (dgvPasswords[k, i].Value != null)
                    {
                        table.AddCell(new Phrase(dgvPasswords[k, i].Value.ToString()));

                    }
                }
            }

            doc.Add(paragraph);
            doc.Add(table);
            doc.Close();
          //  MessageBox.Show("Exported as Export-List.pdf to \n\n" + Application.StartupPath + " /Export-List.pdf", "PDF Exported", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }

    }

它还包括列复制和列新建按钮.. 做得很完美，但现在我不确定我错过了什么。

如何从 DgvPassword 中仅导出姓名、用户名、密码和更改日期？

Answer 1

由于 k

使用了不正确的上限，您正在尝试访问 dgvPasswords 数组的范围之外

 for (int k = 0; k < dgvPasswords.Columns.Count; k++)
        {

应该阅读

  for (int k = 0; k < dgvPasswords.Rows.Count; k++)
        {
