能否在C#中实现异步版本的远程命令执行？

在C#中，为了实现异步版本的远程命令执行，你可以利用`Task`或`async/await`关键字来提高代码的响应性和并发能力。以下是异步版本的示例：

using System.Threading.Tasks;
using SSH.Net;

...

private async Task<string> ExecuteCommandAsync(string command, SshClient client, SftpSession sftp)
{
    try
    {
        using (var shell = await sftp.OpenShellAsync())
        {
            var output = await shell.ExecuteCommandAsync(command);
            return output.ReadToEnd();
        }
    }
    catch (Exception ex)
    {
        return $"命令执行错误: {ex.Message}";
    }
}

public async Task CheckPublishStatusAsync()
{
    string host = ...;
    // 其他变量如上

    using (var client = new SSHClient(host, port))
    {
        await client.ConnectAsync();
        try
        {
            // 等待认证并创建SFTP会话
            await client.AuthenticateWithPasswordAsync(username, password);
            using (var sftp = await client.CreateSftpSessionAsync())
            {
                string commandOutput = await ExecuteCommandAsync("your_command_here", client, sftp);
                // 检测输出是否包含"发布成功"
                bool isSuccessful = commandOutput.Contains("发布成功");
                // 后续处理...
            }
        }
        finally
        {
            await client.DisconnectAsync();
        }
    }
}
