远程与本地的磁盘使用情况与进程监控

本地磁盘：

//long totalSize = new long();
//str_HardDiskName = str_HardDiskName + ":\";
//System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
//foreach (System.IO.DriveInfo drive in drives)
//{
// if (drive.Name == str_HardDiskName)
// {
// totalSize = drive.TotalSize / (1024 * 1024 * 1024);
// }
//}
//return totalSize;

远程监控磁盘使用情况：

System.Management.ConnectionOptions Conn = new ConnectionOptions();
//设定用于WMI连接操作的用户名

//设定用户的口令
Conn.Password = "ohmydear";
//设定用于执行WMI操作的范围
System.Management.ManagementScope Ms = new ManagementScope("\\" + "10.0.0.254" + "\root\cimv2", Conn);
try

//连接到实际操作的WMI范围

//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

//异步调用WMI查询
