Tabellae I/O operationes pars est momenti ullius linguae programmandi et C# nihil excipit. Utrum fasciculi legendi et scribendi, operandi directoria, an rivorum fasciculi processus, C# bibliothecam classium locupletem et potentem ad haec munera efficiendum praebet. Articulus iste lima ratio I/O operationes in C# in specie inducet, et ostendet quomodo limas et directoria per exempla codicem efficaciter tractandum ostendet.

1. legere et scribere files

scribentes injustitiam file

In C#, uti potesSystem.IOsub spatio nominaliFileClassis ad operas fasciculi scribendas.

Exemplum:

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string path = "example.txt";
        string content = "这是一个示例文本。";
 
        // 写入文件
        File.WriteAllText(path, content);
        Console.WriteLine("文件写入成功。");
    }
}

legere file

Similiter etiam possumus utiFileClassis legere documenta contenta:

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string path = "example.txt";
 
        if (File.Exists(path))
        {
            // 读取文件内容
            string content = File.ReadAllText(path);
            Console.WriteLine("文件内容：");
            Console.WriteLine(content);
        }
        else
        {
            Console.WriteLine("文件不存在。");
        }
    }
}

2. usus file fluminum

Fluminum fasciculi flexibilem viam praebent ad legendos et scribendos ordines praesertim cum magnas fasciculos expediendas, flumina fasciculi byte byte data legere et scribere possunt, ita nimiae memoriae usus vitando.

ususFileStreamscribentes injustitiam file

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string path = "filestream_example.txt";
        byte[] data = System.Text.Encoding.UTF8.GetBytes("通过FileStream写入的数据。");
 
        using (FileStream fs = new FileStream(path, FileMode.Create))
        {
            fs.Write(data, 0, data.Length);
            Console.WriteLine("数据已通过FileStream写入。");
        }
    }
}

ususFileStreamlegere file

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string path = "filestream_example.txt";
 
        using (FileStream fs = new FileStream(path, FileMode.Open))
        {
            byte[] data = new byte[fs.Length];
            fs.Read(data, 0, data.Length);
            string content = System.Text.Encoding.UTF8.GetString(data);
            Console.WriteLine("通过FileStream读取的内容：");
            Console.WriteLine(content);
        }
    }
}

3. Operatio Directory

Creare Directory

In C#, uti potesDirectorygenus creare Directory:

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string dirPath = "example_directory";
 
        if (!Directory.Exists(dirPath))
        {
            Directory.CreateDirectory(dirPath);
            Console.WriteLine("目录创建成功。");
        }
        else
        {
            Console.WriteLine("目录已存在。");
        }
    }
}

delete Directory

potestDirectoryClassis directorium delere:

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string dirPath = "example_directory";
 
        if (Directory.Exists(dirPath))
        {
            Directory.Delete(dirPath, true);
            Console.WriteLine("目录已删除。");
        }
        else
        {
            Console.WriteLine("目录不存在。");
        }
    }
}

4. lima et directoria Traverse

A list of lima in Directory

potestDirectoryClassis numerum accipit documentorum in statis presul:

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string dirPath = "example_directory";
 
        if (Directory.Exists(dirPath))
        {
            string[] files = Directory.GetFiles(dirPath);
            Console.WriteLine("目录中的文件：");
            foreach (string file in files)
            {
                Console.WriteLine(file);
            }
        }
        else
        {
            Console.WriteLine("目录不存在。");
        }
    }
}

Presul recursively percurre

Omnes fasciculi in directorio eiusque subdirectoria percurrere possunt utendo algorithmo recursivo:

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string dirPath = "example_directory";
 
        if (Directory.Exists(dirPath))
        {
            TraverseDirectory(dirPath);
        }
        else
        {
            Console.WriteLine("目录不存在。");
        }
    }
 
    static void TraverseDirectory(string dirPath)
    {
        string[] files = Directory.GetFiles(dirPath);
        string[] directories = Directory.GetDirectories(dirPath);
 
        foreach (string file in files)
        {
            Console.WriteLine("文件: " + file);
        }
 
        foreach (string directory in directories)
        {
            Console.WriteLine("目录: " + directory);
            TraverseDirectory(directory); // 递归遍历子目录
        }
    }
}

5. File res attributum

In systematis fasciculi operationibus, lectionibus et attributis lima ordinandis communis postulatio est. C # providetFileInfogenus ad hanc functionem efficiendam.

Legere lima attributa

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string filePath = "example.txt";
 
        FileInfo fileInfo = new FileInfo(filePath);
 
        if (fileInfo.Exists)
        {
            Console.WriteLine("文件名: " + fileInfo.Name);
            Console.WriteLine("文件路径: " + fileInfo.FullName);
            Console.WriteLine("文件大小: " + fileInfo.Length);
            Console.WriteLine("创建时间: " + fileInfo.CreationTime);
            Console.WriteLine("最后访问时间: " + fileInfo.LastAccessTime);
            Console.WriteLine("最后修改时间: " + fileInfo.LastWriteTime);
        }
        else
        {
            Console.WriteLine("文件不存在。");
        }
    }
}

Set file possessiones

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string filePath = "example.txt";
 
        FileInfo fileInfo = new FileInfo(filePath);
 
        if (fileInfo.Exists)
        {
            // 设置文件属性
            fileInfo.Attributes = FileAttributes.ReadOnly;
            Console.WriteLine("文件属性已设置为只读。");
 
            // 恢复文件属性
            fileInfo.Attributes = FileAttributes.Normal;
            Console.WriteLine("文件属性已恢复为正常。");
        }
        else
        {
            Console.WriteLine("文件不存在。");
        }
    }
}

6. Asynchronous file I / O res

Modi asynchroni utentes docilitatis tuae applicationis emendare possunt cum magnis fasciculis laborat vel operationes fasciculi tempus consumens exercet. C# methodos asynchronos files legendi et scribendi praebet.

Praesent files asynchronously

using System;
using System.IO;
using System.Threading.Tasks;
 
class Program
{
    static async Task Main()
    {
        string path = "async_example.txt";
        string content = "这是一个异步写入示例。";
 
        await File.WriteAllTextAsync(path, content);
        Console.WriteLine("文件异步写入成功。");
    }
}

Legere files asynchronously

using System;
using System.IO;
using System.Threading.Tasks;
 
class Program
{
    static async Task Main()
    {
        string path = "async_example.txt";
 
        if (File.Exists(path))
        {
            string content = await File.ReadAllTextAsync(path);
            Console.WriteLine("文件内容：");
            Console.WriteLine(content);
        }
        else
        {
            Console.WriteLine("文件不存在。");
        }
    }
}

7. magna File

C # providetFileSystemWatcher Classis vigilantia mutationes lima vel directoria in certa presul. Hoc utile est in applicationibus quae ad emendationes fasciculi respondeant.

ususFileSystemWatcherMonitor lima mutationes

using System;
using System.IO;
 
class Program
{
    static void Main()
    {
        string path = "example_directory";
 
        if (!Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }
 
        FileSystemWatcher watcher = new FileSystemWatcher();
        watcher.Path = path;
        watcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.LastWrite | NotifyFilters.Size;
        watcher.Filter = "*.*";
 
        watcher.Changed += OnChanged;
        watcher.Created += OnChanged;
        watcher.Deleted += OnChanged;
        watcher.Renamed += OnRenamed;
 
        watcher.EnableRaisingEvents = true;
 
        Console.WriteLine("正在监视目录: " + path);
        Console.WriteLine("按任意键退出...");
        Console.ReadKey();
    }
 
    private static void OnChanged(object source, FileSystemEventArgs e)
    {
        Console.WriteLine($"文件: {e.FullPath} {e.ChangeType}");
    }
 
    private static void OnRenamed(object source, RenamedEventArgs e)
    {
        Console.WriteLine($"文件: {e.OldFullPath} 重命名为 {e.FullPath}");
    }
}
