自己做了个读写OPC数据的小程序，只是点击按钮写入，我想实现按下按钮后写入1，松开按钮后写入0，并实时显示在OPC标签中。
刚开始学习，搞了半天没结果，谢谢大神们。
private void button2_Click(object sender, EventArgs e)
{
Array AsyncValue_Wt;
Array SerHandles;
object[] tmpWtData = new object[3];//写入的数据必须是object型的，否则会报错
int[] tmpSerHdles = new int[3];
//将输入数据赋给数组，然后再转成Array型送给AsyncValue_Wt
tmpWtData[1] =??????? ; //tmpWtData[1] = (object)textBox1.Text;
// tmpWtData[2] = (object)textBox2.Text;
AsyncValue_Wt = (Array)tmpWtData;
//将输入数据送给的Item对应服务器句柄赋给数组，然后再转成Array型送给SerHandles
tmpSerHdles[1] = Convert.ToInt32(lserverhandles.GetValue(1));
tmpSerHdles[2] = Convert.ToInt32(lserverhandles.GetValue(2));
SerHandles = (Array)tmpSerHdles;
objGroup.AsyncWrite(2, ref SerHandles, ref AsyncValue_Wt, out lErrors_Wt, lTransID_Wt, out lCancelID_Wt);
}
