Today,it`s my first day to start a new lesson with c#! 

At first ,I want to study it just because java is a old language ,and run slower than c# many person has a bad expect with java

but ,it is a large mass to study ,I can`t confirm if there is a fature in study c# ,so i choose java.

Java is a greate a program langage too. C# is easier,and simpler ,powerful ,I like GUI ,I will write GUi program in C#.

Here is a "HelloWorld"

 

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace FirstCshrap{    class Program    {        static void Main(string[] args)        {            string str;                Console.WriteLine("Please Input a word !");                str = Console.ReadLine();                Console.WriteLine(str);        }    }}
