Reading Data from textfile

Im having problems with figuring out how to do data reading from a .txt file. Im trying to make the .txt file placable in the inpector, by using a TextAsset. But i dont know how to read from the text asset. what im after is getting all the lines in the file as an array of strings, where each line would be its own element in the array.
Any help would be appreciated!
