Help you with what? All you've done is post a copy of your assignment. What part of this are you having a problem with?
Are you looking for someone to write it for you? If so, you've most assuredly come to the WRONG place.

I think it is a kind way of demanding someone do the homework for him. Will get him really far in a job.

Sounds like everything you need is right there in the question. Create the class, add the variables it tell you to add, implement the methods it tells you to implement, then write a short console app that creates your objects and does what the question tells you to do.
This question is about as handholdy as you can get. You'd be lucky if you ever get a specification that precise in the real world.

It's very simple.
He want's exactly what the assignment says. It describes exactly what to do, and even how to do it. There is nothing that you have to figure out, you just have to type in the code.
What he does not want, however, is for you to try to make someone else do the assignment for you.

Go to rent a coder and pay 5 bucks 
On two occasions I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question. - Charles Babbage

First try it yourself. If you really get stuck somewhere post the question here, explain what you've tried and where the problem lies. In that case people are more willing to help you.

When I test the String.Trim() function,my resource codes as follows:
using System;
using System.Collections.Generic;
using System.Text;
namespace Ch05Ex05
{
class Program
{
static void Main(string[] args)
{
string myString = " This is a test. ";
char[] separator = {' '};
char[] test ={ 'T', 'i' };
string[] myWords;
myString = myString.Trim(test);
// myWords = myString.Split(separator);
foreach (char C in myString)
{
Console.WriteLine("{0}", C);
}
Console.ReadKey();
}
}
}
The alphabet T and i should be removed ,but when I excuted my codes,It change nothing! Can you tell me why?

Trim removes occurrences only at the begin or at the end of the string (MSDN):
String.Trim (Char[])
Removes all occurrences of a set of characters specified in an array from
the beginning and end of this instance.

I wiil be happy to be your friend. On the other hand, since I'm Italian, English is not my native language. Moreover I'm not that C# expertise (C++ is my native programming language...). Anyway I will happy to receive your questions...

I think you're looking for .Replace. You can replace T with an empty string.

you can use string builder or you can use the replace function it will repalce the letter T with an empt space

"exit while;"

I could certainly be missing something but I thought this was for VB not C#.

 There's an exit keyword in C#?
|
|

It's from C# language specification:
When multiple switch, while, do, for, or foreach statements are nested within each other, a break statement applies only to the innermost statement. To transfer control across multiple nesting levels, a goto statement (§8.9.3) must be used.
using System;
class Test
{
static void Main(string[] args) {
string[,] table = {
{"Red", "Blue", "Green"},
{"Monday", "Wednesday", "Friday"}
};
foreach (string str in args) {
int row, colm;
for (row = 0; row <= 1; ++row)
for (colm = 0; colm <= 2; ++colm)
if (str == table[row,colm])
goto done;
Console.WriteLine("{0} not found", str);
continue;
done:
Console.WriteLine("Found {0} at [{1}][{2}]", str, row, colm);
}
}
}

Ahhhh! Not the notorious goto! 
|
|
|
|

Well, I don't much like goto myself but that's the way Microsoft specifications provide. The good thing is that at least all finally blocks are still processed so not much harm is done. Sometimes goto is far more comprehensive than additional boolean flags and checks in nested loops.
|
|
|
|

It's not notorious when used to branch to the end of a block. In fact, that's what break and return do.
Djikstra's paper has to do with branching into a control block, there making program verification orders of magnitude more difficult.

I guess you could have a boolean flag as part of the while loop, bool isBreakingFromDefault, and just set that flag to true when you break from default. When the while loop sees that flag as true, break from the while loop as well.
FWIW, I think the switch construct is butt ugly and often confusing. I'd much rather see a few if/elses.

Wow - I think the reverse. They are, of course, the same thing in the end.
