推荐答案

试试这个

你必须改变 DrawMode 从正常到 OwnerDrawText 并更改中的颜色drawNode 活动

Try this
You have to Change the DrawMode from Normal to OwnerDrawText and Change the color in drawNode event

private void Form1_Load(object sender, EventArgs e)
       {
           treeView1.DrawMode = TreeViewDrawMode.OwnerDrawText;
       }


       SolidBrush greenBrush = new SolidBrush(Color.Green);

       private void treeView1_drawNode(object sender, DrawTreeNodeEventArgs e)
       {
           if (e.Node.IsSelected)
           {
               if (treeView1.Focused)
                   e.Graphics.FillRectangle(greenBrush, e.Bounds);
           }
           else
               e.Graphics.FillRectangle(Brushes.White, e.Bounds);

           TextRenderer.DrawText(e.Graphics,    e.Node.Text,  e.Node.TreeView.Font,  e.Node.Bounds,  e.Node.ForeColor);
       }
