怎么把参数传递给System.Windows.Forms.Timer？

private System.Windows.Forms.Timer timer;
timer.Interval = 1000;
timer.Tick += new EventHandler(timer_Tick);
timer.start

private void timer_Tick(object sender, EventArgs e)
{

}

我怎样才能传递对象的值sender？

如何在C#中使用OPCDA.NET获取OPCGroup的非公共成员的值

private void DataChangeHandler(object sender, DataChangeEventArgs e)
{
   try
   {
       object obj = sender;
       OpcGroup grp = (OpcGroup)sender; // I want the OPCgroup non public member value

       if (InvokeRequired)
       {
           BeginInvoke(new DataChangeEventHandler(DataChangeHandler), 
                       new object[] { sender, e });
           //return;
       }
       if (parameter.X == 0)
       {
           parameter.X = 1;
           Thread th = new Thread(param.update);
           th.Start(e);
       }
   }
   catch(OPCException ) { }
}

我想在运行时在C#中创建一个动态数组,然后使用这个变量数组值:

  int z = 0;
  int k=0;
  int[] err11;
  if (y == 1)
  {
       while(z < laddrslt)
       {
            if (addRslt[z].Error < 0)
            {
                 err[]=new int[k];

                 err11[k] = item[z].HandleClient ;
                 k++;
             }
             z++;
        }
   }

   if (err11.Length < addRslt.Length)
   {
        //code
   }
