四．C＃重启远程计算机的重要步骤和实现方法：
（1）.连接远程计算机：
按照下列语句可以实现连接远程计算机：
ConnectionOptions options = new ConnectionOptions ( ) ;
options.Username ="管理者帐号用户名";
options.Password = "管理者帐号口令" ;
ManagementScope scope = new ManagementScope( "\\\\" + "远程计算机名或IP地址" + "\\root\\cimv2", options ) ;
//用给定管理者用户名和口令连接远程的计算机
scope.Connect ( ) ;
（2）.得到在远程计算机中可以进行WMI控制：
System.Management.ObjectQuery oq = new System.Management.ObjectQuery ( "SELECT * FROM Win32_OperatingSystem" ) ;
ManagementObjectSearcher query1 = new ManagementObjectSearcher ( scope , oq ) ;
//得到WMI控制
ManagementObjectCollection queryCollection1 = query1.Get ( ) ;
（3）.调用WMI控制，实现重启远程计算机：
foreach ( ManagementObject mo in queryCollection1 )
{
string [ ] ss= { "" } ;
//重启远程计算机
mo.InvokeMethod ( "Reboot" , ss ) ;
}
五．C＃实现重启远程计算机的源程序代码（boot.cs）和执行界面：
在了解了C＃实现重启远程计算机的这些重要步骤后，就可以从容的得到重启远程计算机的完整代码，具体如下：
using System ;
using System.Drawing ;
using System.Collections ;
using System.ComponentModel ;
using System.Windows.Forms ;
using System.Data ;
using System.Management ;
public class Form1 : Form
{
private TextBox textBox1 ;
private TextBox textBox2 ;
private TextBox textBox3 ;
private Label label1 ;
private Label label2 ;
private Label label3 ;
private Button button1 ;
private System.ComponentModel.Container components = null ;
public Form1 ( )
{
//初始化窗体中的各个组件
InitializeComponent ( ) ;
}
//清除程序中使用过的资源
protected override void Dispose ( bool disposing )
{
if ( disposing )
{
if ( components != null )
{
components.Dispose ( ) ;
}
}
base.Dispose ( disposing ) ;
}
private void InitializeComponent ( )
{
textBox1 = new TextBox ( ) ;
textBox2 = new TextBox ( ) ;
textBox3 = new TextBox ( ) ;
label1 = new Label ( ) ;
label2 = new Label ( ) ;
label3 = new Label ( ) ;
button1 = new Button ( ) ;
SuspendLayout ( ) ;
textBox1.Location = new System.Drawing.Point ( 140 , 46 ) ;
= "textBox1" ;
textBox1.Size = new System.Drawing.Size ( 172 , 21 ) ;
textBox1.TabIndex = 0 ;
textBox1.Text = "" ;
textBox2.Location = new System.Drawing.Point ( 138 , 85 ) ;
= "textBox2" ;
textBox2.Size = new System.Drawing.Size ( 174 , 21 ) ;
textBox2.TabIndex = 1 ;
textBox2.Text = "" ;
textBox3.Location = new System.Drawing.Point ( 139 , 120 ) ;
= "textBox3" ;
textBox3.PasswordChar = '*' ;
textBox3.Size = new System.Drawing.Size ( 173 , 21 ) ;
textBox3.TabIndex = 2 ;
textBox3.Text = "" ;
label1.Location = new System.Drawing.Point ( 24 , 50 ) ;
= "label1" ;
label1.Size = new System.Drawing.Size ( 120 , 16 ) ;
label1.TabIndex = 1 ;
label1.Text = "机器名称或IP地址：" ;
label2.Location = new System.Drawing.Point ( 37 , 88 ) ;
= "label2" ;
label2.TabIndex = 1 ;
label2.Text = "管理者名称：" ;
label2.TextAlign = System.Drawing.ContentAlignment.TopRight ;
label3.Location = new System.Drawing.Point ( 37 , 125 ) ;
= "label3" ;
label3.Size = new System.Drawing.Size ( 100 , 16 ) ;
label3.TabIndex = 1 ;
label3.Text = "管理者密码：" ;
label3.TextAlign = System.Drawing.ContentAlignment.TopRight ;
button1.Location = new System.Drawing.Point ( 95 , 168 ) ;
= "button1" ;
button1.Size = new System.Drawing.Size ( 136 , 32 ) ;
button1.TabIndex = 3 ;
button1.Text = "重新启动远程计算机" ;
button1.Click += new System.EventHandler ( button1_Click ) ;
this.AutoScaleBaseSize = new System.Drawing.Size ( 6 , 14 ) ;
this.ClientSize = new System.Drawing.Size ( 336 , 245 ) ;
this.Controls.Add ( button1 ) ;
this.Controls.Add ( textBox1 ) ;
this.Controls.Add ( textBox2 ) ;
this.Controls.Add ( textBox3 ) ;
this.Controls.Add ( label1 ) ;
this.Controls.Add ( label2 ) ;
this.Controls.Add ( label3 ) ;
= "Form1" ;
this.Text = "利用C＃重新启动远程计算机" ;
this.ResumeLayout(false) ;
}
static void Main ( )
{
Application.Run ( new Form1 ( ) ) ;
}
private void button1_Click ( object sender , System.EventArgs e )
{
//定义连接远程计算机的一些选项
ConnectionOptions options = new ConnectionOptions ( ) ;
options.Username = textBox2.Text ;
options.Password = textBox3.Text ;
ManagementScope scope = new ManagementScope( "\\\\" + textBox1.Text + "\\root\\cimv2", options ) ;
try {
//用给定管理者用户名和口令连接远程的计算机
scope.Connect ( ) ;
System.Management.ObjectQuery oq = new System.Management.ObjectQuery ( "SELECT * FROM Win32_OperatingSystem" ) ;
ManagementObjectSearcher query1 = new ManagementObjectSearcher ( scope , oq ) ;
//得到WMI控制
ManagementObjectCollection queryCollection1 = query1.Get ( ) ;
foreach ( ManagementObject mo in queryCollection1 )
{
string [ ] ss= { "" } ;
//重启远程计算机
mo.InvokeMethod ( "Reboot" , ss ) ;
}
}
//报错
catch ( Exception ee ) {
MessageBox.Show ( "连接" + textBox1.Text + "出错，出错信息为：" + ee.Message ) ;
}
}
}
下图是编译上面代码后得到的程序运行界面：

六．总结：
其实WMI控制可以实现很多以前让我们很头痛的操作。并且使用WMI编写的管理程序也比不用WMI来实现同样功能的程序在设计难度上大大减轻。WMI内容十分丰富，重新启动远程计算机只是其中的一个最为基本的操作。在使用WMI控制之前有一点必须记住，就是你必须知道你所要进行操作的远程计算机的超级管理者的帐号，这是使用WMI的一个前提。
