C# treeView是将子节点排列为其父节点的最后一个子节点的代码
C# treeView是将子节点排列为其父节点的最后一个子节点的代码
提问于 2019-04-19 23:43:35
我使用treeView在表单上的treeView中显示序列目录及其子目录和文件，并使用以下方法加载树视图
在表单加载中：
treeView1.Nodes.Clear();
toolTip1.ShowAlways = true;
LoadDirectory("C:\\Windows\\System32\\" + inventedName ); 以及以下3种加载目录、子目录和文件的方法
public void LoadDirectory(string Dir)
{
DirectoryInfo di = new DirectoryInfo(Dir);
TreeNode tds = treeView1.Nodes.Add(di.Name);
tds.Tag = di.FullName;
//tds.StateImageIndex = 0;
tds.ImageIndex = 0;
tds.StateImageIndex = 0;
tds.SelectedImageIndex = 0;
LoadFiles(Dir, tds);
LoadSubDirectories(Dir, tds);
}
private void LoadSubDirectories(string dir, TreeNode td)
{
string[] subdirectoryEntries = Directory.GetDirectories(dir);
// Loop through them to see if they have any other subdirectories
foreach (string subdirectory in subdirectoryEntries)
{
DirectoryInfo di = new DirectoryInfo(subdirectory);
TreeNode tds = td.Nodes.Add(di.Name);
renameNodes(tds);
//tds.StateImageIndex = 0;
tds.Tag = di.FullName;
tds.ImageIndex = 0;
tds.StateImageIndex = 0;
tds.SelectedImageIndex = 0;
LoadFiles(subdirectory, tds);
LoadSubDirectories(subdirectory, tds);
}
}
private void LoadFiles(string dir, TreeNode td)
{
string[] Files = Directory.GetFiles(dir, "*.pdf");
// Loop through them to see files
foreach (string file in Files)
{
FileInfo fi = new FileInfo(file);
TreeNode tds = td.Nodes.Add(fi.Name);
tds.Tag = fi.FullName;
tds.ImageIndex = 1;
tds.StateImageIndex = 1;
tds.SelectedImageIndex = 1;
}
}我的问题是子目录(文件夹)有特定的名称，我不能更改它，例如：
> root
> parent
> 1.0 xxx
> 1.10 xxx
> 1.2 xxx
> 1.3 xxx
> 1.4 xxx
> 1.5 xxx
> 1.6 xxx
> 1.7 xxx
> 1.8 xxx
> 1.9 xxx但我需要它是这样的
> root
> parent
> 1.0 xxx
> 1.2 xxx
> 1.3 xxx
> 1.4 xxx
> 1.5 xxx
> 1.6 xxx
> 1.7 xxx
> 1.8 xxx
> 1.9 xxx
> 1.10 xxx 愚蠢的(1.10xxx)子文件夹必须在(1.9xxx)子文件夹之后，并且正如我所说的，我不能重命名文件夹，这将是错误的，有什么方法可以将其发送到最后一个子文件夹
谢谢你帮我

几周前，我使用IEquable做了一个非常类似的解决方案。我在下面的代码中对文件名进行了排序，以获得正确的解决方案
public class Test
{
private void LoadFiles(string dir, TreeNode td)
{
string[] Files = Directory.GetFiles(dir, "*.pdf");
Files = Files.Select(x => new MySort(x)).OrderBy(x => x).Select(x => x.filename).ToArray();
// Loop through them to see files
foreach (string file in Files)
{
FileInfo fi = new FileInfo(file);
TreeNode tds = td.Nodes.Add(fi.Name);
tds.Tag = fi.FullName;
tds.ImageIndex = 1;
tds.StateImageIndex = 1;
tds.SelectedImageIndex = 1;
}
}
}
public class MySort : IComparable
{
private string[] splitvalues { get; set; }
public string filename { get; set; }
public MySort(string filename)
{
this.filename = filename;
splitvalues = filename.Split(new char[] { '.', ' ' }, StringSplitOptions.RemoveEmptyEntries).ToArray();
}
public int CompareTo(object other)
{
MySort otherMySort = (MySort)other;
int min = Math.Min(this.splitvalues.Length, otherMySort.splitvalues.Length);
for (int i = 0; i < min; i++)
{
string a = this.splitvalues[i];
string b = otherMySort.splitvalues[i];
if (a != b)
{
int numberA = 0;
int numberB = 0;
if (int.TryParse(a, out numberA))
{
if (int.TryParse(b, out numberB))
{
int z = numberA.CompareTo(numberB);
//a & b are numbers
return numberA.CompareTo(numberB);
}
else
{
//a number b string
return -1;
}
}
else
{
if (int.TryParse(b, out numberB))
{
//a string b number
return 1;
}
else
{
// a string b string
return a.CompareTo(b);
}
}
}
}
return splitvalues.Length.CompareTo(otherMySort.splitvalues.Length);
}

正如您从下面的测试代码中所看到的，代码工作正常。我做了一个小改动，添加了Sort()方法，使调用代码变得更容易。其他一切都是一样的。：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
string[] input = { "1.7.1", "1.7.10", "1.7.2", "1.7.3", "1.7.4", "1.7.5", "1.7.6", "1.7.7", "1.7.8", "1.7.9" };
string[] output = MySort.Sort(input);
}
}
public class MySort : IComparable
{
private string[] splitvalues { get; set; }
public string filename { get; set; }
public MySort(string filename)
{
this.filename = filename;
splitvalues = filename.Split(new char[] { '.', ' ' }, StringSplitOptions.RemoveEmptyEntries).ToArray();
}
public static string[] Sort(string[] input)
{
return input.Select(x => new MySort(x)).OrderBy(x => x).Select(x => x.filename).ToArray();
}
public int CompareTo(object other)
{
MySort otherMySort = (MySort)other;
int min = Math.Min(this.splitvalues.Length, otherMySort.splitvalues.Length);
for (int i = 0; i < min; i++)
{
string a = this.splitvalues[i];
string b = otherMySort.splitvalues[i];
if (a != b)
{
int numberA = 0;
int numberB = 0;
if (int.TryParse(a, out numberA))
{
if (int.TryParse(b, out numberB))
{
int z = numberA.CompareTo(numberB);
//a & b are numbers
return numberA.CompareTo(numberB);
}
else
{
//a number b string
return -1;
}
}
else
{
if (int.TryParse(b, out numberB))
{
//a string b number
return 1;
}
else
{
// a string b string
return a.CompareTo(b);
}
}
}
}
return splitvalues.Length.CompareTo(otherMySort.splitvalues.Length);
}
}
