我有一个工具条,其中包含代表目录中找到的文件夹的toolstripdropdownbuttons。我想为每个toolstripdropdownbutton提供一个下拉菜单,以包含找到的子文件夹。一个例子是Internet Explorer链接栏我尝试了以下代码,但我不太清楚如何去做(见图) Links Bar Example
我尝试过的代码:
private void populateLinks()
{
linksToolStrip.Items.Clear();
DirectoryInfo linksFolder = new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.Favorites) + "\\Links");
foreach (DirectoryInfo linksDirectory in linksFolder.GetDirectories())
{
Image favImage = Properties.Resources.Folder;
ToolStripDropDownButton button = new ToolStripDropDownButton();
button.Text = Truncate(linksDirectory.Name, 22);
button.ToolTipText = linksDirectory.Name + "\nDate Created: " + Directory.GetCreationTime(linksDirectory.FullName);
button.Image = favImage;
button.Tag = linksDirectory.FullName;
linksToolStrip.Items.Add(button);
populateLinksFolders(linksDirectory, button.DropDown);
}
和
private void populateLinksFolders(DirectoryInfo subdirectory, ToolStripDropDown tsdd)
{
foreach (DirectoryInfo directory in subdirectory.GetDirectories())
{
populateLinksFolders(directory, ?) //<- Everything tried here fails
}
}
我该如何做到这一点?
答案 0 :(得分:0)
您需要传递ToolStripDropDownButton
,然后使用DropDownItems
属性添加子项。
populateLinksFolders(linksDirectory, button);
然后:
private void populateLinksFolders(DirectoryInfo subdirectory, ToolStripDropDownButton tsddb)
{
foreach (DirectoryInfo directory in subdirectory.GetDirectories())
{
ToolStripDropDownButton button = new ToolStripDropDownButton(directory.Name);
tsddb.DropDownItems.Add(button);
populateLinksFolders(directory, button);
}
}
