如何检查Ssh.NET连接是否成功建立？

Question

我想了解如何Ssh.NET能告诉我，如果连接成功建立：

SshClient client = new SshClient("127.0.0.1", 22, "root", ""); 
client.Connect(); 

// Connection ok? Then continue, else display error 

SshCommand x = client.RunCommand("service apache2 status"); 
client.Disconnect(); 
client.Dispose(); 

而且我怎么证明的结果“client.RunCommand（”服务的Apache2状态“）; “逻辑？
例如如果（X == “的Apache2运行”）

Answer 1

您可以检查SshClient.IsConnected属性：

if (!client.IsConnected) 
{ 
    // Display error 
} 

Answer 2

您可以使用client.IsConnected这个

using (var client = new SshClient("127.0.0.1", 22, "root", "")) { 
    client.Connect(); 

    if (client.IsConnected) { 
     SshCommand x = client.RunCommand("cd ~"); 
    } else { 
     Console.WriteLine("Not connected"); 
    } 

    client.Disconnect(); 
}
