Get text for each line in textbox multiline

[x_nick2001]

I have a textbox with multiline and I want to get the text of each line in it.
Let say the textbox as this in it:

2001:4321:John Doe
2002:4321:Jane Doe
2003:4321:Jack Doe

I will be ok with line having no text in it or only space, so what I want is a way to get "2001:4321:John Doe" into a string and then do some manipulation on it, after get "2002:4321:Jane Doe" do some manipulation and so on...
Just to make it clear number of lines will vary can be none, can be 1 can, be 20...

Tx in advance

I suggest you read the help/MSDN topic for whatever class you are using first, before asking questions on how to use it. That would very quickly have led you to the Lines property.
