C＃OpenFileDialog在multiselect

Question

我正在使用C＃上的OpenFileDialog组件来选择要处理的多个文件。

问题在于，当程序完成foreach循环的执行时，它将重复执行“ private void openFileDialog1_FileOk（object sender，CancelEventArgs e）”方法，弄乱了我的excel电子表格。

如何处理？

这是我的代码：

private void openFileDialog1_FileOk(object sender, CancelEventArgs e)
{

    int i = 2;

    Microsoft.Office.Interop.Excel.Application xla = new Microsoft.Office.Interop.Excel.Application();

    xla.Visible = true;

    Microsoft.Office.Interop.Excel.Workbook wb = xla.Workbooks.Add(Microsoft.Office.Interop.Excel.XlSheetType.xlWorksheet);

    Microsoft.Office.Interop.Excel.Worksheet ws = (Microsoft.Office.Interop.Excel.Worksheet)xla.ActiveSheet;

    ws.Cells[1, 1] = "Test case";
    ws.Cells[1, 2] = "Q Score";
    ws.Cells[1, 3] = "TC Score";

    foreach (String file in openFileDialog1.FileNames)
    {
        try
        {
            StreamReader arq = new StreamReader(file);

            string Title = file;
            Title = Title.Remove(0, Title.LastIndexOf("\\") + 1);
            Title = Title.Remove(Title.LastIndexOf("."), Title.Length - Title.LastIndexOf("."));
            string Title_aux = Title;
            F.Text = "MSA-GA: " + Title;

            string texto = arq.ReadToEnd();

            arq.Close();
            arq.Dispose();
            openFileDialog1.Dispose();

            texto = texto.Replace(" ","");
            texto = texto.Replace("\r\n\r\n", "\r\n");
            texto = texto.Replace("\r\n\r\n", "");

            StreamWriter gravar = new StreamWriter(@"cases\" + Title + ".FASTA");
            gravar.Write(texto);
            gravar.Close();
            gravar.Dispose();

            string Title_ref = Title.Substring(0, (Title.Length - 2));

            // Start the child process.
            Process p = new Process();
            // Redirect the output stream of the child process.
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.Arguments = "/c program -test cases\\" + Title + ".FASTA " + "-ref cases\\" + Title_ref;
            //p.StartInfo.Arguments = "/C dir";
            p.Start();
            // Do not wait for the child process to exit before
            // reading to the end of its redirected stream.
            // p.WaitForExit();
            // Read the output stream first and then wait.
            string output = p.StandardOutput.ReadToEnd();
            p.WaitForExit();

            int pos_ini = output.IndexOf("Q=")+2;
            string q_score = output.Substring(pos_ini, (output.IndexOf(';', pos_ini) - pos_ini));

            pos_ini = output.IndexOf("TC=") + 3;
            string tc_score = output.Substring(pos_ini, (output.IndexOf("\r\n", pos_ini) - pos_ini));

            q_score=q_score.Replace('.', ',');
            tc_score=tc_score.Replace('.', ',');

            ws.Cells[i, 1] = Title;
            ws.Cells[i, 2] = q_score;
            ws.Cells[i, 3] = tc_score;

            i++;
        }
        catch
        {

        }
    }
}

方法如下：

private void openFileDialog1_FileOk(object sender, CancelEventArgs e)

正在通过openFileDialog1.ShowDialog()

调用

private void button1_Click(object sender, EventArgs e)
{
    openFileDialog1.Title = "Open Fasta File";
    openFileDialog1.InitialDirectory = Application.StartupPath;
    openFileDialog1.ShowDialog();
}

Answer 1

您的代码中肯定有一些问题，但您提到的不是。 ShowDialog（）打开对话框并触发所有有线事件。因此，如果多次调用openFileDialog1_FileOk，请检查事件分配。右键单击Visual Studio中的openFileDialog1_FileOk方法，然后选择“查找所有引用”，检查是否有任何异常引用或其他内容。
