取得当前应用程序的windows域名和使用者

需要

using System.Diagnostics;
using System.Management;

Process currentProcess = Process.GetCurrentProcess();

string text1 = null;

SelectQuery query1 = new SelectQuery("Select * from Win32_Process WHERE processID=" + currentProcess.Id);
ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(query1);


try
{
foreach (ManagementObject disk in searcher1.Get())
{
ManagementBaseObject inPar = null;
ManagementBaseObject outPar = null;


inPar = disk.GetMethodParameters("GetOwner");


outPar = disk.InvokeMethod("GetOwner", inPar, null);


text1 = outPar["Domain"].ToString() + ":" + outPar["User"].ToString();
break;
}
}
catch
{
text1 = "SYSTEM";
}


return text1;

同样可以取得其他系统信息

//主板信息：
publicstaticvoidGetBaseBoardInfo()
{
try
{
ManagementObjectSearchersearcher=
newManagementObjectSearcher("Select*FromWin32_BaseBoard");
foreach(ManagementObjectmoinsearcher.Get())
{
//mo["Manufacturer"]，制造商，如“On-data”（昂达）
//mo["Product"]，型号，如“KT400A-8235”
//mo["SerialNumber"]，序列号
}
}
catch
{
}
}

//BIOS信息：
publicstaticvoidGetBiosInfo()
{
try
{
ManagementObjectSearchersearcher=
newManagementObjectSearcher("Select*FromWin32_BIOS");
foreach(ManagementObjectmoinsearcher.Get())
{
//mo["Manufacturer"]，制造商，如“PhoenixTechnologies,LTD”
//mo["SerialNumber"]，序列号
}
}
catch
{
}
}

//物理磁盘信息：
publicstaticvoidGetPhysicalDiskInfo()
{
try
{
ManagementObjectSearchersearcher=
newManagementObjectSearcher("Select*FromWin32_DiskDrive");
foreach(ManagementObjectmoinsearcher.Get())
{
//mo["MediaType"]，类型，如“Fixedharddiskmedia”

}
}
catch
{
}
}

//网卡配置信息：
publicstaticvoidGetNAConfigurationInfo()
{
try
{
ManagementObjectSearchersearcher=
newManagementObjectSearcher("Select*FromWin32_NetworkAdapterConfiguration");
foreach(ManagementObjectmoinsearcher.Get())
{
//mo["IPAddress"]，IP地址
//mo["DefaultIPGateway"]，默认网关
//mo["DNSServerSearchOrder"]，DNS地址，如果有备用则会以数组形式返回
//mo["IPSubnet"]，子网掩码
//mo["MACAddress"]，MAC地址
}
}
catch
{
}
}

//CPU信息：
publicstaticvoidGetProcessorInfo()
{
try
{
ManagementObjectSearchersearcher=
newManagementObjectSearcher("Select*FromWin32_Processor");
foreach(ManagementObjectmoinsearcher.Get())
{
//mo["L2CacheSize"]，二级缓存，如“512”
//mo["Manufacturer"]，制造商，如“AuthenticAMD”
//mo["MaxClockSpeed"]，主频，如“1824”（1.824G）
//mo["ProcessorId"]，ID，如“0383F9FF000006A0”
}
}
catch
{
}
}

//逻辑磁盘信息：
publicstaticvoidGetLogicalDiskInfo()
{
try
{
ManagementObjectSearchersearcher=
newManagementObjectSearcher("Select*FromWin32_LogicalDisk");
foreach(ManagementObjectmoinsearcher.Get())
{
//mo["FileSystem"]，文件系统，如“FAT32”

//mo["Name"]，卷标，如“C：”

}
}
