Hi Sarah Try this... using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { //class Program //{ // static void Main(string[] args) // { // } //} public delegate int Comparer(object obj1 object obj2); public class Name { public string FirstName = null; public string LastName = null; public Name(string first string last) { FirstName = first; LastName = last; } // this is the delegate method handler public static int CompareFirstNames(object name1 object name2) { string n1 = ((Name)name1).FirstName; string n2 = ((Name)name2).FirstName; if (String.Compare(n1 n2) > 0) { return 1; } else if (String.Compare(n1 n2) { return -1; } else { return 0; } } public override string ToString() { return FirstName +   + LastName; } } class SimpleDelegate { Name[] names = new Name[5]; public SimpleDelegate() { names[0] = new Name(Ali Kaya); names[1] = new Name(Ali Tarak); names[2] = new Name(Ali Yilmaz); names[3] = new Name(Derya Birant); names[4] = new Name(Zeynep Ak); } static void Main(string[] args) { SimpleDelegate sd = new SimpleDelegate(); // this is the delegate instantiation Comparer cmp = new Comparer(Name.CompareFirstNames); Console.WriteLine(
Before Sort: 
); sd.PrintNames(); // observe the delegate argument sd.Sort(cmp); Console.WriteLine(
After Sort: 
); sd.PrintNames(); } // observe the delegate parameter public void Sort(Comparer compare) { object temp; for (int i = 0; i { for (int j = i; j { // using delegate compare just like // a normal method if (compare(names[i] names[j]) > 0) { temp = names[i]; names[i] = names[j]; names[j] = (Name)temp; } } } } public void PrintNames() { Console.WriteLine(Names: 
); foreach (Name name in names) { Console.WriteLine(name.ToString()); } Console.ReadLine(); } } } Thanks If this post helps you mark it as answer

Satyapriya note that the best way to help a student is to help them figure out how to solve a class assignment. It is easier for us to just write the program ourself but that is not what helps the student the most. In fact a student could potentially be thrown out of a university for plagiarizing which is a fancy word for turning in someone else's work as if the student did it. Hopefully Sarah will study the source code you provided and understand it well enough to convince her instructor that she understands it. I think students should be concerned that their instructor might look for questions such as this to catch students that are cheating.
