C#获取系统信息

方法一：利用注册表获取

//RegistryKey 类所需要的包：

//RegistryKey 类所需要的包：

using Microsoft.Win32;

//DllImport方法所需要的包：

using System.Runtime.InteropServices;

//StringBuilder所需要的包：

using System.Text;

//声明API函数

[DllImport("kernel32")]

public static extern void GetWindowsDirectory(StringBuilder WinDir,int count);

[DllImport("kernel32")]

public static extern void GetSystemDirectory(StringBuilder SysDir,int count);

[DllImport("kernel32")]

public static extern void GetSystemInfo(ref CPU_INFO cpuinfo);

[DllImport("kernel32")]

public static extern void GlobalMemoryStatus(ref MEMORY_INFO meminfo);

[DllImport("kernel32")]

public static extern void GetSystemTime(ref SYSTEMTIME_INFO stinfo);

//定义以下各结构

//定义CPU的信息结构

[StructLayout(LayoutKind.Sequential)]

public uint dwProcessorType;

public uint dwAllocationGranularity;

public uint dwProcessorLevel;

public uint dwProcessorRevision;

}

//定义内存的信息结构
