在c#中针对IO的解决方案中使用线程

using System;
using System.IO;
using System.Threading.Tasks;

class Program
{
    static async Task Main(string[] args)
    {
        string filePath = "example.txt";
        await WriteToFileAsync(filePath, "Hello, World!");
        string content = await ReadFromFileAsync(filePath);
        Console.WriteLine(content);
    }

    static async Task WriteToFileAsync(string filePath, string text)
    {
        using (StreamWriter writer = new StreamWriter(filePath))
        {
            await writer.WriteAsync(text);
        }
    }

    static async Task<string> ReadFromFileAsync(string filePath)
    {
        using (StreamReader reader = new StreamReader(filePath))
        {
            return await reader.ReadToEndAsync();
        }
    }
}
