System.Management命名空间里面提供了相关方法,注意ConnectionOptions类\ManagementScope 类登几个类,示例:
long mb = 1048576 ;
//1024x1024
//设定生成的WMI所需的所有设置
System.Management.ConnectionOptions Conn = new ConnectionOptions ( ) ;
//设定用于WMI连接操作的用户名
Conn.Username = 用户名;
//设定用户的口令
Conn.Password = 密码;
//设定用于执行WMI操作的范围
System.Management.ManagementScope Ms = new ManagementScope ( "\\\\" + 机器名或ip + "\\root\\cimv2" , Conn ) ;
try
{
//连接到实际操作的WMI范围
Ms.Connect ( ) ;
//设定通过WMI要查询的内容
ObjectQuery Query = new ObjectQuery ( "select FreeSpace ,Size ,Name from Win32_LogicalDisk where DriveType=3" ) ;
//WQL语句,设定的WMI查询内容和WMI的操作范围,检索WMI对象集合
ManagementObjectSearcher Searcher = new ManagementObjectSearcher ( Ms , Query ) ;
//异步调用WMI查询
ManagementObjectCollection ReturnCollection = Searcher.Get ( ) ;
double free = 0 ;
double use = 0 ;
double total = 0 ;
listBox1.Items.Clear ( ) ;
//通过对产生的WMI的实例集合进行检索,获得硬盘信息
foreach ( ManagementObject Return in ReturnCollection )
{
listBox1.Items.Add ( "磁盘名称:" + Return["Name"].ToString ( ) ) ;
//获得硬盘的可用空间
free = Convert.ToInt64 ( Return["FreeSpace"] ) /mb ;
//获得硬盘的已用空间
use = ( Convert.ToInt64 ( Return["Size"] ) - Convert.ToInt64 ( Return["FreeSpace"] ) ) /mb ;
//获得硬盘的合计空间
total = Convert.ToInt64 ( Return["Size"] ) /mb ;
listBox1.Items.Add ( " 总计:"+ total.ToString ( ) + "MB" ) ;
listBox1.Items.Add ( "已用空间:"+ use.ToString ( ) + "MB" ) ;
listBox1.Items.Add ( "可用空间:"+ free.ToString ( ) + "MB" ) ;
}
}
catch ( Exception ee )
{
MessageBox.Show ( "连接" + textBox1.Text + "出错,出错信息为:" + ee.Message ,"出现错误!" ) ;
}
