C# StreamReader:如何绑定同步ReadBlock调用的最大时间？

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string filePath = "path/to/your/file.txt";

        using (StreamReader reader = new StreamReader(filePath))
        {
            // 设置最大等待时间为500毫秒
            reader.ReadTimeout = 500;

            try
            {
                char[] buffer = new char[1024];
                int bytesRead = reader.ReadBlock(buffer, 0, buffer.Length);

                // 处理读取到的数据
                Console.WriteLine($"Read {bytesRead} characters: {new string(buffer, 0, bytesRead)}");
            }
            catch (IOException ex)
            {
                // 处理读取超时异常
                Console.WriteLine("Read operation timed out: " + ex.Message);
            }
        }
    }
}
