本教程在虚拟机XP+VS2010下测试成功。
首先下载源码：SharpSSH-1.1.1.13.src.zip。
然后用vs2010打开项目，右键SharpSSH（不是Example）点击生成，然后在SharpSSH-1.1.1.13.src\SharpSSH\bin\Release或者（Debug）目录下生成有三个DLL文件。
自己用C#调用SharpSSH库实现连接主机功能简单代码示例如下:
代码段1：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using Tamir.SharpSsh;

namespace SSHTest
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                string host = "192.168.8.8";
                string user = "test";
                string pass = "1234";

                Console.WriteLine("主机地址: {0}", host);
                Console.WriteLine("登陆用户: {0}", user);
                Console.WriteLine("登录密码: {0}", pass);

                SshShell shell = new SshShell(host, user);
                shell.Password = pass;

                shell.RedirectToConsole();
                Console.Write("正在连接...");
                shell.Connect();
                Console.WriteLine("连接完毕！");
                Console.WriteLine("=========");

                while (shell.ShellOpened)
                {
                    System.Threading.Thread.Sleep(500);
                }

                Console.WriteLine("=========");
                Console.WriteLine("断开连接中...");
                shell.Close();
                Console.WriteLine("断开完毕");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

            Console.Write("按任意键继续...");
            Console.ReadKey();
            Console.WriteLine("\b");
            Environment.Exit(0);
        }
    }
}

注意这段代码需要更改自己linux主机的用户名密码，并添加dll引用。
