用C#获取CPU编号、硬盘编号等系统有关环境、属性

如果利用C#获取系统有关环境和属性，这个也是在网上问得比较多的问题，不过大部分只有提问没有回答，最近正好想做有关方面的东西，整理了一下，提供给大家，希望能给大家提供参考意见：

首先需要定义几个结构(struct)，便于DllImport作为返回参数调用。以下是代码：
CpuInfo.cs

usingSystem;
usingSystem.Configuration;
usingSystem.Runtime.InteropServices;

/**//**
*LayoutKind.Automatic：为了提高效率允许运行态对类型成员重新排序
*注意：永远不要使用这个选项来调用不受管辖的动态链接库函数。
*LayoutKind.Explicit：对每个域按照FieldOffset属性对类型成员排序
*LayoutKind.Sequential：对出现在受管辖类型定义地方的不受管辖内存中的类型成员进行排序。
*/

/**////<summary>
///定义CPU的信息结构
///</summary>
[StructLayout(LayoutKind.Sequential)]
publicstructCpuInfo
...{
/**////<summary>
///OEMID
///</summary>
publicuintdwOemId;
/**////<summary>
///页面大小
///</summary>
publicuintdwPageSize;
publicuintlpMinimumApplicationAddress;
publicuintlpMaximumApplicationAddress;
publicuintdwActiveProcessorMask;
/**////<summary>
///CPU个数
///</summary>
publicuintdwNumberOfProcessors;
/**////<summary>
///CPU类型
///</summary>
publicuintdwProcessorType;
publicuintdwAllocationGranularity;
/**////<summary>
///CPU等级
///</summary>
publicuintdwProcessorLevel;
publicuintdwProcessorRevision;
}

MemoryInfo.cs

usingSystem;
usingSystem.Configuration;
usingSystem.Runtime.InteropServices;

/**//**
*LayoutKind.Automatic：为了提高效率允许运行态对类型成员重新排序
*注意：永远不要使用这个选项来调用不受管辖的动态链接库函数。
*LayoutKind.Explicit：对每个域按照FieldOffset属性对类型成员排序
*LayoutKind.Sequential：对出现在受管辖类型定义地方的不受管辖内存中的类型成员进行排序。
*/
/**////<summary>
///定义内存的信息结构
///</summary>
[StructLayout(LayoutKind.Sequential)]
publicstructMemoryInfo
...{
/**////<summary>
///
///</summary>
publicuintdwLength;
/**////<summary>
///已经使用的内存
///</summary>
publicuintdwMemoryLoad;
/**////<summary>
///总物理内存大小
///</summary>
publicuintdwTotalPhys;
/**////<summary>
///可用物理内存大小
///</summary>
publicuintdwAvailPhys;
/**////<summary>
///交换文件总大小
///</summary>
publicuintdwTotalPageFile;
/**////<summary>
///可用交换文件大小
///</summary>
publicuintdwAvailPageFile;
/**////<summary>
///总虚拟内存大小
///</summary>
publicuintdwTotalVirtual;
/**////<summary>
///可用虚拟内存大小
///</summary>
publicuintdwAvailVirtual;
}

SystemTimeInfo.cs

usingSystem;
usingSystem.Configuration;
usingSystem.Runtime.InteropServices;

/**//**
*LayoutKind.Automatic：为了提高效率允许运行态对类型成员重新排序
*注意：永远不要使用这个选项来调用不受管辖的动态链接库函数。
*LayoutKind.Explicit：对每个域按照FieldOffset属性对类型成员排序
*LayoutKind.Sequential：对出现在受管辖类型定义地方的不受管辖内存中的类型成员进行排序。
*/
/**////<summary>
///定义系统时间的信息结构
///</summary>
[StructLayout(LayoutKind.Sequential)]
publicstructSystemTimeInfo
...{
/**////<summary>
///年
///</summary>
publicushortwYear;
/**////<summary>
///月
///</summary>
publicushortwMonth;
/**////<summary>
///星期
///</summary>
publicushortwDayOfWeek;
/**////<summary>
///天
///</summary>
publicushortwDay;
/**////<summary>
///小时
///</summary>
publicushortwHour;
/**////<summary>
///分钟
///</summary>
publicushortwMinute;
/**////<summary>
///秒
///</summary>
publicushortwSecond;
/**////<summary>
///毫秒
///</summary>
publicushortwMilliseconds;
}

另外还定义了一个调用类SystemInfo.cs，代码如下：

usingSystem;
usingSystem.Configuration;
usingSystem.Runtime.InteropServices;
usingSystem.Management;
usingSystem.Text;

/**////<summary>

}

[DllImport("kernel32")]
privatestaticexternvoidGetSystemDirectory(StringBuilderSysDir,intcount);

[DllImport("kernel32")]
privatestaticexternvoidGetSystemInfo(refCpuInfocpuInfo);

[DllImport("kernel32")]
privatestaticexternvoidGlobalMemoryStatus(refMemoryInfomemInfo);

[DllImport("kernel32")]
privatestaticexternvoidGetSystemTime(refSystemTimeInfosysInfo);

/**////<summary>
///查询CPU编号
///</summary>
///<returns></returns>
publicstringGetCpuId()
...{
ManagementClassmClass=newManagementClass("Win32_Processor");
ManagementObjectCollectionmoc=mClass.GetInstances();
stringcpuId=null;
foreach(ManagementObjectmoinmoc)
...{
cpuId=mo.Properties["ProcessorId"].Value.ToString();
break;
}
returncpuId;
}

/**////<summary>

///</summary>
///<returns></returns>
publicstringGetMainHardDiskId()
...{
ManagementObjectSearchersearcher=newManagementObjectSearcher("SELECT*FROMWin32_PhysicalMedia");
StringhardDiskID=null;
foreach(ManagementObjectmoinsearcher.Get())
...{
hardDiskID=mo["SerialNumber"].ToString().Trim();
break;
}
returnhardDiskID;
}

/**////<summary>

publicstringGetWinDirectory()
...{
StringBuildersBuilder=newStringBuilder(CHAR_COUNT);
GetWindowsDirectory(sBuilder,CHAR_COUNT);
returnsBuilder.ToString();
}

/**////<summary>

///</summary>
///<returns></returns>
publicstringGetSysDirectory()
...{
StringBuildersBuilder=newStringBuilder(CHAR_COUNT);
GetSystemDirectory(sBuilder,CHAR_COUNT);
returnsBuilder.ToString();
}

/**////<summary>

///<returns></returns>
publicCpuInfoGetCpuInfo()
...{
CpuInfocpuInfo=newCpuInfo();
GetSystemInfo(refcpuInfo);
returncpuInfo;
}

/**////<summary>

publicMemoryInfoGetMemoryInfo()
...{
MemoryInfomemoryInfo=newMemoryInfo();
GlobalMemoryStatus(refmemoryInfo);
returnmemoryInfo;
}

/**////<summary>

publicSystemTimeInfoGetSystemTimeInfo()
...{
SystemTimeInfosystemTimeInfo=newSystemTimeInfo();
GetSystemTime(refsystemTimeInfo);
returnsystemTimeInfo;
}

/**////<summary>

///<returns></returns>
publicstringGetOperationSystemInName()
...{
OperatingSystemos=System.Environment.OSVersion;
stringosName="UNKNOWN";
switch(os.Platform)
...{
casePlatformID.Win32Windows:
switch(os.Version.Minor)
...{
case0:osName="Windows95";break;
case10:osName="Windows98";break;
case90:osName="WindowsME";break;
}
break;
casePlatformID.Win32NT:
switch(os.Version.Major)
...{
case3:osName="WindwsNT3.51";break;
case4:osName="WindowsNT4";break;
case5:if(os.Version.Minor==0)
...{

}
elseif(os.Version.Minor==1)
...{

}
elseif(os.Version.Minor==2)
...{
osName="WindowsServer2003";
}
break;
case6:osName="Longhorn";break;
}
break;
}
returnString.Format("{0},{1}",osName,os.Version.ToString());
}
}

以下是调用实例，为了简单，我在一个aspx页面中输出，不过这个程序可以在WinForm中调用：

usingSystem;
usingSystem.Data;
usingSystem.Configuration;
usingSystem.Collections;
usingSystem.Collections.Specialized;
usingSystem.Web;
usingSystem.Web.Security;
usingSystem.Web.UI;
usingSystem.Web.UI.WebControls;
usingSystem.Web.UI.WebControls.WebParts;
usingSystem.Web.UI.HtmlControls;
usingSystem.Runtime.InteropServices;

publicpartialclassIndex:System.Web.UI.Page
...{
protectedvoidPage_Load(objectsender,EventArgse)
...{
if(!Page.IsPostBack)
...{
SystemInfosystemInfo=newSystemInfo();
Response.Write("操作系统："+systemInfo.GetOperationSystemInName()+"<br>");
Response.Write("CPU编号："+systemInfo.GetCpuId()+"<br>");
Response.Write("硬盘编号："+systemInfo.GetMainHardDiskId()+"<br>");
Response.Write("Windows目录所在位置："+systemInfo.GetSysDirectory()+"<br>");
Response.Write("系统目录所在位置："+systemInfo.GetWinDirectory()+"<br>");
MemoryInfomemoryInfo=systemInfo.GetMemoryInfo();
CpuInfocpuInfo=systemInfo.GetCpuInfo();
Response.Write("dwActiveProcessorMask"+cpuInfo.dwActiveProcessorMask+"<br>");
Response.Write("dwAllocationGranularity"+cpuInfo.dwAllocationGranularity+"<br>");
Response.Write("CPU个数："+cpuInfo.dwNumberOfProcessors+"<br>");
Response.Write("OEMID："+cpuInfo.dwOemId+"<br>");
Response.Write("页面大小"+cpuInfo.dwPageSize+"<br>");
Response.Write("CPU等级"+cpuInfo.dwProcessorLevel+"<br>");
Response.Write("dwProcessorRevision"+cpuInfo.dwProcessorRevision+"<br>");
Response.Write("CPU类型"+cpuInfo.dwProcessorType+"<br>");
Response.Write("lpMaximumApplicationAddress"+cpuInfo.lpMaximumApplicationAddress+"<br>");
Response.Write("lpMinimumApplicationAddress"+cpuInfo.lpMinimumApplicationAddress+"<br>");
Response.Write("CPU类型："+cpuInfo.dwProcessorType+"<br>");
Response.Write("可用交换文件大小："+memoryInfo.dwAvailPageFile+"<br>");
Response.Write("可用物理内存大小："+memoryInfo.dwAvailPhys+"<br>");
Response.Write("可用虚拟内存大小"+memoryInfo.dwAvailVirtual+"<br>");
Response.Write("操作系统位数："+memoryInfo.dwLength+"<br>");
Response.Write("已经使用内存大小："+memoryInfo.dwMemoryLoad+"<br>");
Response.Write("交换文件总大小："+memoryInfo.dwTotalPageFile+"<br>");
Response.Write("总物理内存大小："+memoryInfo.dwTotalPhys+"<br>");
Response.Write("总虚拟内存大小："+memoryInfo.dwTotalVirtual+"<br>");
}
}
}

说明：前台aspx页面没有任何控件。
