C#字体格式设置

1、字体设置，比如宋体，9号大小，斜体

TreeNode rootNode1 = new TreeNode();
rootNode1.Text = "Locals";
treeView1.Nodes.Add(rootNode1);//添加根节点          
TreeNode rootNodeSub1 = new TreeNode();
rootNodeSub1.Text = "<Right click to insert Local>";
rootNode1.Nodes.Add(rootNodeSub1);//添加子节点            
rootNodeSub1.NodeFont = font;
