C#源码刷新网页最小化托盘http get和post请求配置保存版权时间限制定时调用单实例运行，如果已经运行则激活窗口到最前显示

C#源码功能示例：刷新网页、最小化托盘、http get和post请求、配置保存、版权时间限制、定时调用、单实例运行，如果已经运行则激活窗口到最前显示等。

单实例运行激活窗口调用

using System.Threading;namespace HTMLWindowsFormsApplication3
{static class Program{/// <summary>/// 应用程序的主入口点。/// </summary>[STAThread]static void Main(){Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);SoftHelper.SoftSingle<Form1>(); //单实例运行，已运行则激活窗口// Application.Run(new Form1());//bool createdNew; //Mutex instance= new Mutex(true, "互斥名(保证在本机中唯一)", out createdNew);//if(createdNew)//{//    Application.EnableVisualStyles();//    Application.SetCompatibleTextRenderingDefault(false);//    Application.Run(new Form1());//    instance.ReleaseMutex();//}//else//{//    MessageBox.Show("已经启动了一个程序，请先退出！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Error);//    Application.Exit();//}}}
