//1.1 添加节点TreeNode tn1 = treeView1.Nodes.Add("名称");TreeNode tn2 = treeView1.Nodes.Add("类别");TreeNode subA_tn1 = new TreeNode("A");TreeNode subB_tn1 = new TreeNode("B");TreeNode subC_tn1 = new TreeNode("C");tn1.Nodes.Add(subA_tn1);tn1.Nodes.Add(subB_tn1);tn1.Nodes.Add(subC_tn1);TreeNode sub1_tn2 = new TreeNode("1");TreeNode sub2_tn2 = new TreeNode("2");TreeNode sub3_tn2 = new TreeNode("3");tn2.Nodes.Add(sub1_tn2);tn2.Nodes.Add(sub2_tn2);tn2.Nodes.Add(sub3_tn2);//1.2 移除节点private void button1_Click(object sender, EventArgs e){	treeView1.Nodes.Remove(treeView1.SelectedNode);}//1.3 为节点设置图标imageList1.Images.Add(Image.FromFile("图片地址1"));imageList1.Images.Add(Image.FromFile("图片地址2"));treeView1.ImageList = imageList1;treeView1.ImageIndex = 0;treeView1.SelectedImageIndex = 1;

2. ProgressBar

progressBar1.Value = 0;progressBar1.Minimum = 0;progressBar1.Maximum = 500;progressBar1.Step = 1;for(int i=0; i<=500; i++){	progressBar1.PerformStep();}
