openfiledialog, open already in use textfile

Question

Been searching a while and can't seem to find any answer to my problem. I want to be able to open a file which is already in use. This is the code I use to open the file with:

OpenFileDialog openFile1 = new OpenFileDialog();


openFile1.Filter = "Text Files|*.log";
openFile1.Multiselect = true;
openFile1.Title = "Open log files";

if (openFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    richTextBox1.LoadFile(openFile1.FileName, RichTextBoxStreamType.PlainText);

_textArray = richTextBox1.Lines;

You can try to copy the file first and then open the copy but if that also fails you're out of luck. — rene, Sep 27 '14 at 19:25

You cannot do this unless the other entity which has the file open allows for shared reads. Therefore, you must open the filestream with the FileShare.ReadWrite parameter.

There are some already answers to this.
