Visual Basic StreamReader - Importing a csv file into an array

Hi all

I have a set of data in csv format, numbers only. It is 2 columns x 111 (varying length) array. It will always be 2 columns.

I am struggling to get the data into an array to manipulate it further.

Can anyone help how I can get the 2 column csv file into a double array?

I have got it working into a textbox using txt.Text = StreamToDisplay.ReadToEnd, but struggling with getting it into an array

Thanks
