我正在使用treeView在treeView上显示序列目录及其子目录和文件，我使用以下方法加载树视图
表单加载：
treeView1.Nodes.Clear();
toolTip1.ShowAlways = true;
LoadDirectory("C:\Windows\System32\" + inventedName );
以及以下3种加载目录和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(有特定名称，我无法更改它例如：
> 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
但我需要它像那样
> 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 (1.10 XXX( 孩子必须在 (1.9 XXX( 孩子之后正如我所说，我无法重命名错误的文件夹，有什么方法可以将其发送到最后一个孩子
谢谢你帮助我
几周
前我使用IEquable做了一个非常相似的解决方案。 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);
}
}
代码工作正常，从下面的测试代码中可以看出。 我做了一个小的更改来添加一个 Sort(( 方法，以便更轻松地调用代码。 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);
}
}
}
