如何检查Ssh.NET连接是否成功建立

Question

我想知道Ssh.NET如何告诉我连接是否成功建立：

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();

我如何从逻辑上证明"client.RunCommand（"service-apache2-status"）；"的结果
例如，如果（x="apache2正在运行"）

Answer 1

您可以检查SshClient.IsConnected属性：

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

Answer 2

您可以使用客户端。已为此连接

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();
}

Answer 3

尝试使用IsConnected属性

If cSSH.IsConnected Then
    Dim x As SshCommand = cSSH.RunCommand("service apache2 status")
    con.Text = "Success"
Else
    con.Text = "Error! Connection Failed"
End If
