如何使用SSH.NET限制上传速度？

using Renci.SshNet;
using System.IO;

// 创建SSH连接
var connectionInfo = new ConnectionInfo("hostname", "username", new PasswordAuthenticationMethod("username", "password"));
using (var client = new SftpClient(connectionInfo))
{
    client.Connect();

    // 打开本地文件
    using (var fileStream = new FileStream("localFilePath", FileMode.Open))
    {
        // 创建SFTP上传流
        using (var uploadStream = client.OpenWrite("remoteFilePath"))
        {
            // 创建限速流，限制上传速度为100KB/s
            using (var throttledStream = new ThrottledStream(uploadStream, 100 * 1024))
            {
                // 将本地文件流复制到限速流
                fileStream.CopyTo(throttledStream);
            }
        }
    }

    client.Disconnect();
}
