C# thread02功能:01.主要實作如何利用類別(ThreadWithState)方式傳遞參數給執行緒
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Threading;//step 01
namespace CS_thread
{
public class ThreadWithState
{
private double value;
public ThreadWithState(double number)
{

}
public void ThreadProc()
{
while (true)
{
Form1.m_dblcount += this.value;
Thread.Sleep(3000);
}
}
}
public partial class Form1 : Form
