    用C#获取系统有关环境、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 using  System; using  System.Configuration; using  System.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)]  public   struct  CpuInfo {    /// <summary>    /// OEM ID    /// </summary>    public uint dwOemId;    /// <summary>    /// 页面大小    /// </summary>    public uint dwPageSize;    public uint lpMinimumApplicationAddress;    public uint lpMaximumApplicationAddress;    public uint dwActiveProcessorMask;    /// <summary>    /// CPU个数    /// </summary>    public uint dwNumberOfProcessors;    /// <summary>    /// CPU类型    /// </summary>    public uint dwProcessorType;    public uint dwAllocationGranularity;    /// <summary>    /// CPU等级    /// </summary>    public uint dwProcessorLevel;    public uint dwProcessorRevision; } MemoryInfo.cs using  System; using  System.Configuration; using  System.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)] public   struct  MemoryInfo {    /// <summary>    ///     /// </summary>    public uint dwLength;    /// <summary>    /// 已经使用的内存    /// </summary>    public uint dwMemoryLoad;    /// <summary>    /// 总物理内存大小    /// </summary>    public uint dwTotalPhys;    /// <summary>    /// 可用物理内存大小    /// </summary>    public uint dwAvailPhys;    /// <summary>    /// 交换文件总大小    /// </summary>    public uint dwTotalPageFile;    /// <summary>    /// 可用交换文件大小    /// </summary>    public uint dwAvailPageFile;    /// <summary>    /// 总虚拟内存大小    /// </summary>    public uint dwTotalVirtual;    /// <summary>    /// 可用虚拟内存大小    /// </summary>    public uint dwAvailVirtual;} SystemTimeInfo.cs using  System; using  System.Configuration; using  System.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)]  public   struct  SystemTimeInfo {    /// <summary>    /// 年    /// </summary>    public ushort wYear;    /// <summary>    /// 月    /// </summary>    public ushort wMonth;    /// <summary>    /// 星期    /// </summary>    public ushort wDayOfWeek;    /// <summary>    /// 天    /// </summary>    public ushort wDay;    /// <summary>    /// 小时    /// </summary>    public ushort wHour;    /// <summary>    /// 分钟    /// </summary>    public ushort wMinute;    /// <summary>    /// 秒    /// </summary>    public ushort wSecond;    /// <summary>    /// 毫秒    /// </summary>    public ushort wMilliseconds;} 另外还定义了一个调用类SystemInfo.cs,代码如下: using  System;
