如何通过套接字tcp从客户端到服务器和服务器向客户端发送字符串数组？我找不到任何解决方案......我试图将字符串数组转换为字节数组并返回。但是我得到了记忆力不足......

private static byte[] ToByteArray(string[] input)
{
    using (var stream = new MemoryStream())
    using (var writer = new BinaryWriter(stream, Encoding.UTF8))
    {
        var rows = input.GetLength(0);
        writer.Write(rows);
        for (int i = 0; i < rows; i++)
        {
            writer.Write(input[i]);
        }
        return stream.ToArray();
    }
}

private static string[] FromByteArray(byte[] input)
{
    using (var stream = new MemoryStream(input))
    using (var reader = new BinaryReader(stream, Encoding.UTF8))
    {
        var rows = reader.ReadInt32();
        var result = new string[rows];
        for (int i = 0; i < rows; i++)
        {
            result[i] = reader.ReadString();
        }
        return result;
    }
}

在编写二进制数据时，BinaryWriter在调用MemoryStream.ToArray()时仍然可以包含缓冲数据。这会导致具有二进制数据的数组不完整。首先刷新BinaryWriter：

writer.Flush();
return stream.ToArray();

C＃通过socket发送字符串数组
