磁盘配额的WMI版本（还是使用C#）

using System;
using System.Management;
namespace DiskQuota

[STAThread]
static void Main(string[] args)
{
try
{
ManagementClass c = new ManagementClass("Win32_DiskQuota");
ManagementObject quota = c.CreateInstance();
quota["Limit"] = 400000000;
quota["WarningLimit"] = 200000000;
// Get user account object
ManagementObject account = new
ManagementObject("Win32_Account.Domain=TODAY20040216,Name=ASPNET");
account.Get();
// get disk object
ManagementObject disk = new
ManagementObject("Win32_LogicalDisk.DeviceId='F:'");
disk.Get();
quota["QuotaVolume"] = disk;
quota["User"] = account;
quota.Put(); // commit

ManagementClass c = new ManagementClass("Win32_DiskQuota");
Console.WriteLine(c.SystemProperties);
foreach (ManagementObject o in c.GetInstances())
Console.WriteLine("Next : {0}", o.Path);
}
catch(Exception e)
{
Console.WriteLine("error:" + e);
}
}
}
}
说明：使用了.NET的management的组件。
