是程序运行的入口点:
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
单实例限制代码:
[STAThread]
static void Main()
{
bool isAppRunning = false;
System.Threading.Mutex mutex = new System.Threading.Mutex(true, System.Diagnostics.Process.GetCurrentProcess().ProcessName, out isAppRunning);
if (!isAppRunning)
{
MessageBox.Show("本程序已经在运行了,请不要重复运行!");
Environment.Exit(1);
}
else
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
