Deleting lines from text file

I'm making a multiple questions quiz on the console application. What I am trying to complete right now is the updating/deleting of questions.

I would really appreciate any help and also note that I'm new so if I have missed anything please let me know as I am not familiar with Stack Overflow.

I would prefer to use streamreader and writer to read and write to the file as I am a little familiar with these.

Here is my code structure for the variables to be saved in the textfile. 

public struct Questions
    {
        public int 
               Level,               //1
               Qnum;                //2

        public string 
               Q,                   //The capital of England A)? B)London C)? D)?
               A;                   //B
    }

I feel ridiculous as if I should know how to do this but I am just not capable of doing it, any help is much appreciated.

You have to read the file and store the string in your code, then remove the line from the string and write it back on the file.
