About C# Delegates and Lambdas

I. Requirements: Create a C# program that uses delegates and lambda expressions to find the minimum element in a generic array.

Create a method with the signature: T findMin(T[] arr, Funccomparison). This method should find and return the minimum element in the generic array arr passed as the first parameter to the method.

The method’s second parameter comparison must be a generic delegate that takes two parameters and returns a bool value. All instances that implement this delegate must return true when the delegate’s first parameter is smaller (precedes) than the second parameter – otherwise the delegate instances must return false.

The code inside the findMin method should use the delegate instance passed as the second parameter to compare array elements and to select the minimum one.

To test your code create two structures:
Person with at least two data fields – stringName and intAge;
Student with at least two data fields – stringStudentID and double GPA.

In your Main() method create two arrays – one of type Person and the other of type Student.

Populate each array with at least five unique elements.

Using lambda expressions generate three delegate instances that follow item 2 requirements. Then call the findMin method with proper delegate parameters, display the values returned by this method, and verify that the minimum elements were actually found correctly. Use the following combinations of arrays/lambdas as parameters to the findMin method:
Array of type Person and lambda that compares Person instances using the Age field.
Array of type Student and lambda that compares Student instances using the StudentID field.
Array of type Student and lambda that compares Student instances using the GPA field.

II.

Code a generic method int findLast(T[] arr, T target, Funcequality) that searches the array arr for the element equal to the target parameter and returns the index of the last found element or -1 if the search fails.

The method’s third parameter equality must be a generic delegate that takes two parameters of the same type and returns a bool value. All instances that implement this delegate must return true when the delegate’s first parameter is equal to the second parameter – otherwise the delegate instances must return false.

The code inside the findLast method should use the delegate instance passed as the third parameter to check if at least one array element is equal to the target parameter.

Test the findLast method with at least 3 delegates using guidelines described in requirements 4 – 7.
