远程重启服务器的程序

今天通过远程桌面重启服务器失败了，远程桌面就登录不进去了，不过还是能ping通的，为了能接着工作，就写了下面的代码去重启服务器。使用System.Mangement命名空间需要引用System.Mangement。

namespace Test
{
    public partial class RebootServer : Form
    {
        public RebootServer()
        {
            InitializeComponent();
        }

        /**//// <summary>

            StringBuilder strTemp = new StringBuilder();
            ConnectionOptions options = new ConnectionOptions();

            if (textBox2.Text != "Computer Name or IP" && textBox2.Text.Trim() != string.Empty)
            {
                strComputerName = textBox2.Text.Trim();
            }
            else
            {
                MessageBox.Show("Please enter computer name.");
                return;
            }

            options.Username = @"ENT\MSI Drone";
            options.Password = "aaa";
            ManagementScope scope = new ManagementScope("\\\\" + strComputerName + "\\root\\cimv2", options);

                    strTemp.Append("Computer Name : " + m["csname"].ToString() + "\r\n");

                    strTemp.AppendLine();
                }

                textBox1.Text = strTemp.ToString();
            }
            catch (Exception ex)
