//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(); }
