C#基礎入門指南

閒來無事，捯飭一下C#

編譯腳本：

@echo off

set PATH=C:\Windows\Microsoft.NET\Framework\v4.0.30319;%PATH%

echo "compile c# use csc cmd tool"

csc /t:exe /out:demo.exe csDemo.cs Person.cs SynchronThread.cs
::csc /t:library /r:System.Web.dll /out:demo.dll Person.cs csDemo.cs

pause

demo.exe

pause

主函數：

using System;
using Stage1;

namespace Stage1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello c#!!!");
            
            Person zhangsan = new Person();
            zhangsan.name = "zhangsan";
            zhangsan.age = 18;
            zhangsan.say();
            
            //線程測試！！！
            SynchronThread hthread = new SynchronThread();
            hthread.startThread();
        }
    }
}

格式類：

using System;

namespace Stage1
{
    public class Person
    {
        public string name;
        public int age;
        
        public void say()
        {
            string message = string.Format("name=({0}), age=({1})", name, age);
            System.Console.WriteLine(message);
            System.Console.WriteLine("my name is {0}, {1:d2} old, time:{2 :dd/MM/yyyy}!", name, age, System.DateTime.Now);
            System.Console.WriteLine("{0,10:d3} old!", age);//對齊10，長度3不足補0
        }
    }
}

線程類：

using System;//Console
using System.Collections.Generic;//List
using System.Threading;//Thread

class SynchronThread
{    
    public void startThread()
    {
        childref = new ThreadStart(SynchronThread.ThreadFunc);
        Console.WriteLine("In main thread....ManagedThreadId={0}", Thread.CurrentThread.ManagedThreadId);
        //
        childThread_1 = new Thread(childref);
        childThread_2 = new Thread(SynchronThread.ThreadFunc);
        //
        if (null != childThread_1 && null != childThread_2)
        {
            childThread_1.Start();
            childThread_2.Start();
            
            //
            list_students.Add("zhangsan");
            list_students.Add("lisi");
            list_students.Add("wangwu");
            
            Console.ReadKey();
        }
    }
    
    public static void ThreadFunc()
    {
        Monitor.Enter(Lock);
        //lock(Lock)
        {
            for (int i=0; i<10; i++)
            {
                count += 1;
                Console.WriteLine("In Child thread...., ManagedThreadId={0}, count = {1}", Thread.CurrentThread.ManagedThreadId.ToString() , count);
            }
            for(int i=0; i<list_students.Count;i++)
            {
                Console.WriteLine("In Child thread...., student name={0}", list_students[i]);
            }
            foreach(string name in list_students)
            {
                Console.WriteLine("In Child thread...., student name={0}", name);
            }
        }
        Monitor.Exit(Lock);        
    }
    
    
    private ThreadStart childref;    
    private Thread childThread_1;
    private Thread childThread_2;
    
    //
    private static List<string> list_students = new List<String>();
    private static int count = 0;
    private static readonly object Lock = new object();
}
