C# WinForm设置TreeView选中节点

这里假定只有两级节点，多级方法类似。
遍历节点，根据选中节点文本找到要选中的节点。
treeView.SelectedNode = selectNode;

 /// <summary>
 /// 设置TreeView选中节点
 /// </summary>
 /// <param name="treeView"></param>
 /// <param name="selectStr">选中节点文本</param>
 private void SelectTreeView(TreeView treeView, string selectStr)
 {
     treeView.Focus();
     for (int i = ; i < treeView.Nodes.Count; i++)
     {
         for (int j = ; j < treeView.Nodes[i].Nodes.Count; j++)
         {
             if (treeView.Nodes[i].Nodes[j].Text == selectStr)
             {
                 treeView1.SelectedNode = treeView.Nodes[i].Nodes[j];//选中
                 //treeView.Nodes[i].Nodes[j].Checked = true;
                 treeView.Nodes[i].Expand();//展开父级
                 return;
             }
         }
     }
 }
