Windows service and Win32_DiskQuota
- 0
Hi,
I want get the actual quota's assigned to a user account.
The code is as follows.
public class QuotaInformation
{
public String DiskSpaceUsed;
public String Limit;
public String QuotaVolume;
public String User;
}
.
.
.
void GetQuotaInformation()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher(@"\root\cimv2",
"SELECT DiskSpaceUsed, Limit, QuotaVolume, User FROM Win32_DiskQuota");
foreach (ManagementObject queryObj in searcher.Get())
{
Console.WriteLine("Disk Space Used: " + queryObj["DiskSpaceUsed"].ToString());
Console.WriteLine("Limit: " + queryObj["Limit"].ToString());
Console.WriteLine("QuotaVolume:" + queryObj["QuotaVolume"].ToString());
Console.WriteLine("User: " + queryObj["User"].ToString());
QuotaInformation quotaInfo = new QuotaInformation();
quotaInfo.DiskSpaceUsed = queryObj["DiskSpaceUsed"].ToString();
quotaInfo.Limit = queryObj["Limit"].ToString();
quotaInfo.QuotaVolume = queryObj["QuotaVolume"].ToString();
quotaInfo.User = queryObj["User"].ToString();
}
}
when i used the code in the windows application. it works. it gets the actual quota
inforamation for each user account on my computer.
However, i used the code in the windows service. it gets quota information only for
Asministrater. not for the other users (for example, dad, mam, and grampa).
How I can get the quota information for all the users on my computer.
Thanks for reading.

Hi, hedwig
I tested the following code in a windows service and succeeded:
(Set Service Account to LocalSystem instead of User to test)
Code Snippetpublic class QuotaInformation
{
public String DiskSpaceUsed;
public String Limit;
public String QuotaVolume;
public String User;
}
string str = string.Empty;
void GetQuotaInformation()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher(@"\root\cimv2",
"SELECT DiskSpaceUsed, Limit, QuotaVolume, User FROM Win32_DiskQuota");
foreach (ManagementObject queryObj in searcher.Get())
{
str += "Disk Space Used: " + queryObj["DiskSpaceUsed"].ToString() + Environment.NewLine;
str += "Limit: " + queryObj["Limit"].ToString() + Environment.NewLine;
str += "QuotaVolume:" + queryObj["QuotaVolume"].ToString() + Environment.NewLine;
str += "User: " + queryObj["User"].ToString() + Environment.NewLine;
QuotaInformation quotaInfo = new QuotaInformation();
quotaInfo.DiskSpaceUsed = queryObj["DiskSpaceUsed"].ToString();
quotaInfo.Limit = queryObj["Limit"].ToString();
quotaInfo.QuotaVolume = queryObj["QuotaVolume"].ToString();
quotaInfo.User = queryObj["User"].ToString();
}
}
protected override void OnStart(string[] args)
{
// TODO: Add code here to start your service.
GetQuotaInformation();
FileStream fs = new FileStream(@"D:\testService.txt", FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter m_streamWriter = new StreamWriter(fs);
m_streamWriter.BaseStream.Seek(0, SeekOrigin.End);
m_streamWriter.WriteLine("testService: Service Started" + DateTime.Now.ToString() + "\n");
m_streamWriter.Write(str);
m_streamWriter.Flush();
m_streamWriter.Close();
fs.Close();
}
Then check the testService.txt file under D: directory.
Please give a try.
Thanks
