获取计算机的信息（IP地址、MAC地址、CUP序列号、硬盘序列号、主板信息等等）

1、Windows Management Instrumentation（WMI）提供了获取信息的方法，在C#中可用通过System.Management命名空间中的类访问。比如获取CPU ID的方法：

string GetCpuID()

{

try

{

string id = "";

ManagementClass mc = new ManagementClass("Win32_Processor");

ManagementObjectCollection moc = mc.GetInstances();

foreach (ManagementObject mo in moc)

{

id = mo.Properties["ProcessorId"].Value.ToString();

}

return id;

}

catch

{

return "unknow";

}

}

2、那么像“Win32_Processor”、“ProcessorId”一类的字符串该如何写？这里有详细说明：



http://msdn.microsoft.com/en-us/library/aa394084(VS.85).aspx

比如主板信息的Win32_BaseBoard类：

class Win32_BaseBoard : CIM_Card

{

string Caption;

string ConfigOptions[];

string CreationClassName;

real32 Depth;

string Description;

real32 Height;

boolean HostingBoard;

boolean HotSwappable;

datetime InstallDate;

string Manufacturer;

string Model;

string Name;

string OtherIdentifyingInfo;

string PartNumber;

boolean PoweredOn;

string Product;

boolean Removable;

boolean Replaceable;

string RequirementsDescription;

boolean RequiresDaughterBoard;

string SerialNumber;

string SKU;

string SlotLayout;

boolean SpecialRequirements;

string Status;

string Tag;

string Version;

real32 Weight;

real32 Width;

};

如果我们想知道主板的SerialNumber，参照Win32_BaseBoard类的红色文字，我们就可以写出如下代码：

string GetMotherBoardSerialNumber()

{

try

{

string sn = "";

ManagementClass mc = new ManagementClass("Win32_BaseBoard");

ManagementObjectCollection moc = mc.GetInstances();

foreach (ManagementObject mo in moc)

{

sn = mo.Properties["SerialNumber"].Value.ToString();

}

return sn;

}

catch

{

return "unknow";

}

}

3、例子：

注释部分是在测试机器上得到的值。

private void CpuInfo()

{

try

{

ManagementClass mc = new ManagementClass("Win32_Processor");

ManagementObjectCollection moc = mc.GetInstances();

foreach (ManagementObject mo in moc)

{

UInt16 AddressWidth = (UInt16)(mo.Properties["AddressWidth"].Value);//32

UInt16 DataWidth = (UInt16)(mo.Properties["DataWidth"].Value);//32

UInt32 CurrentClockSpeed = (UInt32)(mo.Properties["CurrentClockSpeed"].Value);//2810

UInt32 MaxClockSpeed = (UInt32)(mo.Properties["MaxClockSpeed"].Value);//2810

UInt32 ExtClock = (UInt32)(mo.Properties["ExtClock"].Value);//200

string Manufacturer = mo.Properties["Manufacturer"].Value.ToString();//GenuineIntel

string Caption = mo.Properties["Caption"].Value.ToString();//x86 Family 15 Model 4 Stepping 7

string Name = mo.Properties["Name"].Value.ToString();//Intel(R) Pentium(R) D CPU 2.80GHz

string SocketDesignation = mo.Properties["SocketDesignation"].Value.ToString();//socket775

}

}

catch (Exception ex)

{

Console.WriteLine("unknow");

}

}

private void GetMotherBoardInfo()

{

try

{

ManagementClass mc = new ManagementClass("Win32_BaseBoard");

ManagementObjectCollection moc = mc.GetInstances();

foreach (ManagementObject mo in moc)

{

string Manufacturer = mo.Properties["Manufacturer"].Value.ToString();//ASUSTeK Computer INC.

string Name = mo.Properties["Name"].Value.ToString();//底板

string Product = mo.Properties["Product"].Value.ToString();//P5PL2

string SlotLayout = mo.Properties["SlotLayout"].Value.ToString();//在测试机器上没有得到该信息

string Version = mo.Properties["Version"].Value.ToString();//Rev 1.xx

}

}

catch(Exception ex)

{

Console.WriteLine("unknow");

}

}

private void DiskInfo()

{

try

{

ManagementClass mc = new ManagementClass("Win32_DiskDrive");

ManagementObjectCollection moc = mc.GetInstances();

foreach (ManagementObject mo in moc)

{

string InterfaceType = mo.Properties["InterfaceType"].Value.ToString();//IDE

string Model = mo.Properties["Model"].Value.ToString();//MAXTOR 6L080J4

string Name = mo.Properties["Name"].Value.ToString();//\\.\PHYSICALDRIVE0

UInt32 Partitions = (UInt32)(mo.Properties["Partitions"].Value);//1

UInt64 Size = (UInt64)(mo.Properties["Size"].Value);//80048424960

UInt64 TotalCylinders = (UInt64)(mo.Properties["TotalCylinders"].Value);//9732

UInt32 TotalHeads = (UInt32)(mo.Properties["TotalHeads"].Value);//255

UInt64 TotalSectors = (UInt64)(mo.Properties["TotalSectors"].Value);//156344580

UInt64 TotalTracks = (UInt64)(mo.Properties["TotalTracks"].Value);//2481660

}

}

catch (Exception ex)

{

Console.WriteLine(ex.Message);

}

}

4、用WMI获得信息也存在一个小问题，就是比较慢，性能不好。如果对性能有要求，就要通过平台调用的方式调用Win32相关函数。比如通过下面函数可得到物理内存大小等信息：

[DllImport("kernel32")]

private static extern void GlobalMemoryStatus(ref MemoryInfo memInfo);
