如何用代码设置treeview的节点

Answer 1

TreeNode ftn = new TreeNode();
ftn.Text = "父节点(F1)";
ftn.Value = "";
treeMenu.Nodes.Add(ftn);

TreeNode ctn1 = new TreeNode();
ctn1.Text = "F1的子节点(F11)";
ctn1.Value = "";
ftn.ChildNodes.Add(ctn1); //把ctn1节点添加到ftn做为子节点

TreeNode ctn11 = new TreeNode();
ctn11.Text = "F11的子节点";
ctn11.Value = "";
ctn1.ChildNodes.Add(ctn11); //把ctn11节点添加到ctn1做为子节点

TreeNode ctn2 = new TreeNode();
ctn2.Text = "F1的子节点";
ctn2.Value = "";
ftn.ChildNodes.Add(ctn2); //把ctn2节点添加到ftn做为第二个子节点

Answer 2

实例TreeNode或者TreeNode[] 然后treeview的实例.Nodes.Add();
