Perhaps you should make an attempt to do your homework yourself. When that doesn't succeed, ask a specific code related question that addresses your area of difficulty. We are not going to do your assignment for you.

perhaps you should keep quite if you cant help

Marcus Kramer's comment was constructive keeping in view the purpose of home work. He said in the comment to ask code related question, which indicates that people will be interested to help if you have tried something. Your comment shows that you have not taken the suggestion in right perspective.

For a lousy attitude.

Agreed.
The OP has not taken your comment in the right perspective. Please see my comment to OP's comment.

I dont care for your vote it is not that i am running for president. Your attitude is very arrogant. Were you born writing code? or you learned too some where?.. I didn't ask you to do it, but how to do it. Which VJ did that.

I wasn't born writing code, but I certainly was born to write code. :)
And you did ask for someone else to do it: "any sample code..."

No inclusion of code as to what the OP has tried, it's a repost

The following steps can be used to read the data from the text file into List<string>s

Read the entire content of the text file using File.ReadAllText method explained here http://msdn.microsoft.com/en-us/library/ms143368.aspx[^] into a string
Split this string into an array of main array strings using Regex.Split method with the pattern @"}\s*{"
Write a method which takes a string as parameter and returns a List<string>
Inside the method use Regex.Matches method with the pattern @"{([^{}]*)}", which captures the elements within { } as group elements
Create a List<string>, add each match.Groups[1].Value to this list and return this constructed List
Pass each string obtained in step 2 to this method to obtain each inner list
