Csharp TreeView 文件夹 struct 异常

Rename the TreeNode objects Before creating the Directories个

这里有一个根据Jimi's条建议重命名给定文件夹的方法.

• 创建Dictionary<string, string>以将目标文件夹作为关键字，并将新名称作为值.
• 对于每个TreeView个控件，在临时TreeView中克隆其 node 以更改目标 node 的.Text个属性，而不将其反映在主TreeView个控件上.重命名父 node 和/或子 node 时，必须设置.Text属性才能获得正确的.FullPath属性.

private void SomeButton_Click(object sender, EventArgs e)
{
    var driveF = "C:\\";
    var driveZ = "D:\\";
    var selDir = loremDropDown.SelectedValue.ToString();
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();
    var dirsToRename = new Dictionary<string, string>
    {
        { "Book 4", "Book 1" },
        { "Book 5", "Book 2" },
        { "Book 6", "Book 3" },
        { "Books", "Books 123" }
    };

    using (var tv = new TreeView())
    {
        tv.Nodes.AddRange(pathLorem.Nodes
            .OfType<TreeNode>()
            .Select(n => n.Clone() as TreeNode)
            .ToArray());

        foreach (var node in GetCheckedNodes(tv.Nodes))
        {
            if (dirsToRename.ContainsKey(node.Text)) node.Text = dirsToRename[node.Text];
            var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));
            Directory.CreateDirectory(sPath);
            if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveF.ToArray()));
        }

        tv.Nodes.Clear();
        tv.Nodes.AddRange(ipsumPath.Nodes
            .OfType<TreeNode>()
            .Select(n => n.Clone() as TreeNode)
            .ToArray());

        foreach (var node in GetCheckedNodes(tv.Nodes))
        {
            if (dirsToRename.ContainsKey(node.Text)) node.Text = dirsToRename[node.Text];
            var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));
            Directory.CreateDirectory(sPath);
            if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveZ.ToArray()));
        }

        foreach (var shortcut in shortcuts)
        {
            var dirF = $"{driveF}{shortcut}";
            var dirZ = $"{driveZ}{shortcut}";

            if (Directory.Exists(dirF) && Directory.Exists(dirZ))
            {
                CreateShortcut(dirF, dirZ);
                CreateShortcut(dirZ, dirF);
            }
        }
    }
}

Rename given TreeNode objects based on destinations个

keys 取自ComboBox控制键.

private void btnTest_Click(object sender, EventArgs e)
{
    var driveF = "C:\\";
    var driveZ = "D:\\";
    var selDir = loremDropDown.SelectedValue.ToString();
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();
    var dirsToRename = new Dictionary<string, string>
    {
        { "Book 1", "Book 4" },
        { "Book 2", "Book 5" },
        { "Book 3", "Book 6" }
    };

    foreach (var node in GetCheckedNodes(pathLorem.Nodes))
    {
        var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));

        // Comment this if `pathLorem` is not the source of the keys...
        if (dirsToRename.ContainsKey(node.Text))
            sPath = Path.Combine(Path.GetDirectoryName(sPath), dirsToRename[node.Text]);

        Directory.CreateDirectory(sPath);

        if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveF.ToArray()));
    }

    foreach (var node in GetCheckedNodes(ipsumPath.Nodes))
    {
        var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));

        // Comment this if `ipsumPath` is not the source of the keys...
        if (dirsToRename.ContainsKey(node.Text))
            sPath = Path.Combine(Path.GetDirectoryName(sPath), dirsToRename[node.Text]);

        Directory.CreateDirectory(sPath);

        if (node.Level == 0) shortcuts.Add(sPath.TrimStart(driveZ.ToArray()));
    }

    foreach (var shortcut in shortcuts)
    {
        var dirF = $"{driveF}{shortcut}";
        var dirZ = $"{driveZ}{shortcut}";

        if (Directory.Exists(dirF) && Directory.Exists(dirZ))
        {
            CreateShortcut(dirF, dirZ);
            CreateShortcut(dirZ, dirF);
        }
    }
}

您可以添加一个像DataGridView这样的控件来获得dirsToRename字典的键-值对，而不是硬编码.

Rename a Directory after creating it个

您可以通过分别调用File和Directory类的.Move方法来重命名系统文件或目录.

// Rename a file...
File.Move("source", "destination");

// Rename a directory...
Directory.Move("source", "destination");

Map a selected Directory to another个

要将所选目录从ComboBox映射到另一个目录，请根据目标目录(例如Book3_projects_render)的位置更改destPathF或destPathZ(不是两者).

例如:

private void SomeButton_Click(object sender, EventArgs e)
{
    var driveF = "C:\\";
    var driveZ = "D:\\";
    var selDirInfo = loremDropDown.SelectedItem as DirectoryInfo;
    var selDir = selDirInfo.FullName;
    var destPathF = selDir.Replace(Path.GetPathRoot(selDir), driveF);
    var destPathZ = selDir.Replace(Path.GetPathRoot(selDir), driveZ);
    var treeSep = pathLorem.PathSeparator;
    var dirSep = Path.DirectorySeparatorChar.ToString();
    var shortcuts = new HashSet<string>();
    var exDir = "Book 3";
    var repDir = "Book3_projects_render";
    bool isExDir = selDirInfo.Name == exDir;

    if (isExDir)
    {
        // If `Book3_projects_render` is on F: otherwise comment...
        //destPathF = Path.Combine(Path.GetDirectoryName(destPathF), "Book3_projects_render");

        // If `Book3_projects_render` is on Z: otherwise comment...
        destPathZ = Path.Combine(Path.GetDirectoryName(destPathZ), repDir);
    }

    foreach (var node in GetCheckedNodes(pathLorem.Nodes))
    {
        var sPath = Path.Combine(destPathF, node.FullPath.Replace(treeSep, dirSep));
        Directory.CreateDirectory(sPath);
        if (node.Level == 0) shortcuts.Add(sPath.Substring(driveF.Length));
    }

    foreach (var node in GetCheckedNodes(ipsumPath.Nodes))
    {
        var sPath = Path.Combine(destPathZ, node.FullPath.Replace(treeSep, dirSep));
        Directory.CreateDirectory(sPath);
        if (node.Level == 0) shortcuts.Add(sPath.Substring(driveZ.Length));
    }

    foreach (var shortcut in shortcuts)
    {
        var dirF = $"{driveF}{shortcut}";
        var dirZ = $"{driveZ}{shortcut}";

        if (isExDir)
        {
            // If `Book3_projects_render` is on Z: otherwise switch exDir and repDir...
            dirF = dirF.Replace($@"\{repDir}\", $@"\{exDir}\");
            dirZ = dirZ.Replace($@"\{exDir}\", $@"\{repDir}\");
        }

        if (Directory.Exists(dirF) && Directory.Exists(dirZ))
        {
            CreateShortcut(dirF, dirZ);
            CreateShortcut(dirZ, dirF);
        }
    }
}
