TreeView directories in C# WPF
提问by user3271748
I have this code in C# Windows Form Application, but I need it in WPF. Do you have any ideas?
我在 C# Windows 窗体应用程序中有此代码，但我在 WPF 中需要它。你有什么想法？
private void button1_Click(object sender, EventArgs e)
{
ListDirectory(treeView1, "C:\Users\Patrik\Pictures");
}
private void ListDirectory(TreeView treeView, string path)
{
treeView.Nodes.Clear();
var rootDirectoryInfo = new DirectoryInfo(path);
treeView.Nodes.Add(CreateDirectoryNode(rootDirectoryInfo));
}
private static TreeNode CreateDirectoryNode(DirectoryInfo directoryInfo)
{
var directoryNode = new TreeNode(directoryInfo.Name);
foreach (var directory in directoryInfo.GetDirectories())
directoryNode.Nodes.Add(CreateDirectoryNode(directory));
foreach (var file in directoryInfo.GetFiles())
directoryNode.Nodes.Add(new TreeNode(file.Name));
return directoryNode;
}
Thanks for help.
感谢帮助。

In WPF instead of Nodesproperty is Itemsproperty and instead of TreeNodeyou should use TreeViewItem(msdn).
在 WPF 中而不是Nodes属性是Items属性，而不是TreeNode你应该使用TreeViewItem（msdn）。
private void ListDirectory(TreeView treeView, string path)
{
treeView.Items.Clear();
var rootDirectoryInfo = new DirectoryInfo(path);
treeView.Items.Add(CreateDirectoryNode(rootDirectoryInfo));
}
private static TreeViewItem CreateDirectoryNode(DirectoryInfo directoryInfo)
{
var directoryNode = new TreeViewItem { Header = directoryInfo.Name };
foreach (var directory in directoryInfo.GetDirectories())
directoryNode.Items.Add(CreateDirectoryNode(directory));
foreach (var file in directoryInfo.GetFiles())
directoryNode.Items.Add(new TreeViewItem { Header = file.Name });
return directoryNode;
}
