Write a console application in C# with following requirements:

Program Design Requirements:

It should declare a namespace with name same as your Roll no (e.g. if you roll no is “bc000000000” it should declare namespace with name “bc000000000”)

In the above namespace, it should declare a class with the same name (i.e. name of class should be same as your Roll no)

Class should contain a “Verify” method, which should accept a string i.e. roll numberinput from user is passed as argument to this method. Method will verify if it is valid roll number or not. If roll number is valid, method should return “true” otherwise “false”. To verify the roll number, you can declare a string variable in class and initialize with your actual roll number (“verify” method will then compare value of variable in class with that input by user).

Main Function should create object of your class and take student roll number as input from user on console. After this, main program should send this input to “Verify” method to verify input roll number. On the basis of “true/false” value returned by “verify” method, main program should display valid or invalid roll no message.

Output Design Requirements:

Program should:

Display your Welcome note student number at top

Prompt to input your roll number

If valid roll no is entered, it should display the message “You have entered Valid roll number”

On the other hand if invalid roll number is entered, it should display the message “you entered an invalid roll number”.

Please refer to the output snapshots given on next page:

Note: Roll number should be your own student roll number and not any fakes one.  You can use String data type to manipulate roll number.


Note that welcome note and student roll number is displayed at the top and input message is prompted:
