Fixed 鸟粪一样的TreeView下的NodeMouseDoubleClick Bug 

 1  private void treeView1_NodeMouseDoubleClick(object sender, TreeNodeMouseClickEventArgs e) {
 2             Rectangle baseRectangle = this.treeView1.SelectedNode.Bounds;
 3             Point mouseClickPoint = e.Location;
 4 
 5             if (this.treeView1.SelectedNode == e.Node) {
 6                 if (WasInBounds(baseRectangle, mouseClickPoint)) {
 7                     MessageBox.Show(string.Format("the selected node text:{0}", e.Node.Text));
 8                 }
 9             }
10         }
11 
12         /// <summary>
13         /// Return a value indicating whether the click point belong the reactangle region.
14         /// </summary>
15         /// <param name="baseRectangle"></param>
16         /// <param name="clickPoint"></param>
17         /// <returns></returns>
18         private static bool WasInBounds(Rectangle baseRectangle, Point clickPoint) {
19             bool result = true;
20 
21             int bottom = baseRectangle.Bottom;
22             int right = baseRectangle.Right;
23             int left = baseRectangle.Left;
24             int top = baseRectangle.Top;
25 
26             if ((clickPoint.X < left || clickPoint.X > right) || (clickPoint.Y > bottom || clickPoint.Y < top)) {
27                 result = false;
28             }
29 
30             return result;
31         }


废话不多说，用过的人看了代码自然明白
