Question

HELLO, I NEED HELP SOLVING THIS. IT IS FROM STARTING OUT WITH VISUAL C#, 5TH EDITION BY TONY GADDIS. CHAPTER 13, PROGRAMMING PROBLEM #4. I AM REQUIRED TO USE THE LAMBDA EXPRESSIONS TO SOLVE. I HAVE ALREADY ASKED FOR A SOLUTION TO THIS EARLIER, AND THE RESPONSE GIVEN DIDN'T MAKE SENSE. I AM USED TO CODING THAT HAS THE SAME FORMAT AS THE PROGRAMMING QUESTIONS THAT ARE AVAILABLE THROUGH THIS WEBSITE. WHEN YOU SEND A RESPONSE, ARE YOU ABLE TO TELL ME WHERE EACH PIECE OF CODE IS SUPPOSED TO GO?

HERE IS THE PROBLEM THAT NEEDS SOLVING:

English Surnames

In the student sample program files for this chapter, you will find a text file named surnames.txt. The file contains 14,674 English surnames. Each line in the file has one surname. Write a program that reads the names from the file into a List. The program should let the user perform the following searches:

Find all the names that are longer than a specified length.

Find all the names that are shorter than a specified length.

Find all the names that begin with a specified string of characters. (For example, find all the names that begin with “All”.)

Determine whether a specified name exists in the List.
