控件只能夠為主線程 所有 所以只能夠
如下實現(xiàn)

System.Threading.Thread myThread1 ;
delegate void AddNodeDelegate();

myThread1 = new System.Threading.Thread(new System.Threading.ThreadStart(threadone));

void threadone()
{
this.tree.Invoke(new AddNodeDelegate(test);
}

private void test()
{
TreeNode node2 = tree.Nodes.Add("計算機");
olecon.Open();
treefull(node2);
olecon.Close();
}
private void treefull(TreeNode treeNode)
{//遞歸過程
}

這樣就OK了
