我在C#Windows窗体应用程序中有这个代码,但我需要它在WPF中.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;
}
感谢帮助.
解决方法:
在WPF而不是Nodes属性中是Items属性,而不是TreeNode,您应该使用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;
}
