上传文件winForms C#

Question

我正在开发一个Windows应用程序,我想添加一个浏览按钮来上传文件,一旦用户选择要上传的文件或文件(只有pdf文件),我想将它们附加到面板中,当点击任何文件时在adobe reader中打开,因为这些文件是pdf.

Answer 1

浏览按钮单击事件应该是这样的,

private void testButton_Click(object sender, RoutedEventArgs e)
{
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.CheckFileExists = true;
    openFileDialog.AddExtension = true;
    openFileDialog.Multiselect = true;
    openFileDialog.Filter = "PDF files (*.pdf)|*.pdf";

    if (openFileDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        foreach (string fileName in openFileDialog.FileNames)
        {
            Process.Start(fileName);
        }
    }
}

我不确定问题的后半部分.要加载(打开)文件还是上传文件？你究竟想要添加到面板中的是什么？面板只是一个控件容器.
