做外贸如何通过网站精准找到老板联系方法网络推广的基本方法有哪些

一个无聊的测试代码，因为要测试大文件的网络传输，就写了一个随机大文件生成脚本，做个备份。

基本上都是 GPT 生成的，哈哈。

C# 代码

namespace ConsolePlayground;internal class BigFileGenerater
{public async Task Run(){Console.WriteLine("大文件生成工具，输入要生成的文件大小，单位 GB");Console.WriteLine();var input = Console.ReadLine();if (string.IsNullOrWhiteSpace(input)){return;}if (!double.TryParse(input.Trim(), out var size)){return;}if (size <= 0 || size > 1000){throw new ArgumentOutOfRangeException("size");}var byteSize = size * 1024 * 1024 * 1024;var folder = Environment.CurrentDirectory;Console.WriteLine($"将在当前目录 {folder} 生成 {size} GB 的文件");Console.WriteLine("是否继续? Y/N");input = Console.ReadLine();if (string.IsNullOrWhiteSpace(input)){return;}if (input.Trim().ToUpper() != "Y"){return;}Console.WriteLine("开始生成...");await Genetate(folder, byteSize);Console.WriteLine("结束生成");}private async Task Genetate(string folder, double size){var file = Path.Combine(folder, $"TEMP_{DateTime.Now:yyyyMMddHHmmss.fff}.tmp");using var fileStream = new FileStream(file, FileMode.OpenOrCreate);var rng = new Random();int step = 1024 * 1024;int count = (int)Math.Ceiling(size / step);for (int i = 0; i < count; i++){byte[] bytesToWrite = GenerateRandomBytes(rng, step);await fileStream.WriteAsync(bytesToWrite, 0, step);await fileStream.FlushAsync();}}public static byte[] GenerateRandomBytes(Random rng, int length){var randomBytes = new byte[length];rng.NextBytes(randomBytes);return randomBytes;}
}
