C# 多窗口委托通信的实现_C#教程

//*创建委托任务
public delegate void Form_MoreSend_SyncData_To_Form_Main(byte flag, byte count, string data);
public event Form_MoreSend_SyncData_To_Form_Main F_MoreSend_SyncData_To_Main;
//*发送数据
F_MoreSend_SyncData_To_Main(0, 0, "01 23 45 67 89");
 
 
//*同步主窗口数据
public void F_MoreSend_SyncData_From_From_Main(byte flag, byte count, string data)
{
}

//*处理副窗口数据
public void Form_SyncData_From_MoreSend(byte flag, byte count, string data)
{
}
 
//*创建窗口
Form_MoreSend F_MoreSend = new Form_MoreSend();
 
//*按键打开窗口
private void Button_MoreSendData_Click(object sender, EventArgs e)
{
    if (!F_MoreSend.IsHandleCreated) //*未打开则打开
    {
        F_MoreSend = new Form_MoreSend();
		//*建立映射关系，接收副窗口数据
        F_MoreSend.F_MoreSend_SyncData_To_Main += Form_SyncData_From_MoreSend;
//*发送数据到副窗口
        F_MoreSend.F_MoreSend_SyncData_From_From_Main(0, 0, "");
        F_MoreSend.Show();
    }
    else if (F_MoreSend.IsHandleCreated) //*已打开则显示
    {
        if (F_MoreSend.WindowState == FormWindowState.Minimized)
        {
            F_MoreSend.WindowState = FormWindowState.Normal;
        }
        //F_MoreSend.Focus();
        F_MoreSend.TopMost = true;
        F_MoreSend.TopMost = false;
    }
}
