Вот пример этого. В этом примере содержатся значения порядка по значениям релевантности в списке файлов.
CODE:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
// textBox1 for search string
private System.Windows.Forms.TextBox textBox1;
// listView1 for show result
private System.Windows.Forms.ListView listView1;
private System.Windows.Forms.Button button1;
public Form1()
{
InitializeComponent();
}
class MyListViewItem : ListViewItem
{
public int Index { get; set; }
}
private void button1_Click(object sender, EventArgs e)
{
List<MyListViewItem> myList = new List<MyListViewItem>();
// open folder browser to get folder path
FolderBrowserDialog result = new FolderBrowserDialog();
if (result.ShowDialog() == DialogResult.OK)
{
// get all file list
string[] files = Directory.GetFiles(result.SelectedPath);
foreach (string item in files)
{
// find the relevance value based on search string
int count = Regex.Matches(Regex.Escape(item.ToLower()), textBox1.Text.ToLower()).Count;
myList.Add(new MyListViewItem() { Text = item, Index = count });
}
}
List<ListViewItem> list = new List<ListViewItem>();
// add file name in final list with order by relevance value
foreach (var item in myList.OrderByDescending(m => m.Index).ToList())
{
list.Add(new ListViewItem() { Text = item.Text });
}
listView1.Items.AddRange(list.ToArray());
}
}
}
