Solution 1

You can select multiple txt files in the OpenFileDialog box by holding down SHIFT or CTRL keys while selecting the files. This will return an array with the file paths. You can then assign each path to an Open process assigned to a thread,

Another Solution :

OpenFileDialog1.Multiselect = true;

Example:-
Stream myStream = null;
OpenFileDialog Dialog = new OpenFileDialog();
Dialog.Title = "Open Text File";
Dialog.Filter = "TXT files|*.txt";
Dialog.Multiselect = true; //allows to select multiple files in openfiledialog
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// Dialog.InitialDirectory = @"C:\";
if (Dialog.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = Dialog.OpenFile()) != null)
{
using (myStream)
{

string[] filePaths = Directory.GetFiles(@"D:\FolderName", "*.txt", SearchOption.AllDirectories);
foreach (string file in filePaths)
{
rtxtFile.AppendText(System.IO.File.ReadAllText(file));
Thread.Sleep(1000);
}
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
