C# 获取Windows系统信息以及CPU、内存和磁盘使用情况

    一个简单的小工具，主要用来获取当期的电脑信息以及内存的使用情况。本来也没想着写这个玩意，还不如随便下个相关的软件好使，但是前一段时间为了追查系统卡顿的问题，所以就加上了一段统计内存的代码，用来看看是否由这个引起的。

既然统计了内存相关的数据，干脆一不做二不休，又加了下CPU以及硬盘的使用情况统计。

统计的准确不准确我也不好说，因为我也不太能确定，暂且就做个参考值吧。或许使用很多大佬封装过的第三方DLL会准确很多。

下面工具中还展示了部分关于电脑的基本信息数据，这个在之前的时候应该是有发过，我只是单纯的拿了过来（功能实现的多看着洋气）。

主要还是使用windows WMI，虽然下列关于内存情况的统计没用（但其实也可以统计到），因为我感觉这个方式可能稍微准确点。。。

实现功能：

    • 获取系统内存、CPU的使用情况

开发环境：

开发工具：Visual Studio 2013

.NET Framework版本：4.5

实现代码：

 public class SystemUtil    {        #region 内存
        #region 获得内存信息API        [DllImport("kernel32.dll")]        [return: MarshalAs(UnmanagedType.Bool)]        private static extern bool GlobalMemoryStatusEx(ref MEMORY_INFO mi);        //定义内存的信息结构        [StructLayout(LayoutKind.Sequential)]        private struct MEMORY_INFO        {            public uint DWLength; //当前结构体大小            public uint DWMemoryLoad; //当前内存使用率            public ulong ullTotalPhys; //总计物理内存大小            public ulong ullAvailPhys; //可用物理内存大小            public ulong ullTotalPagefile; //总计交换文件大小            public ulong ullAvailPagefile; //总计交换文件大小            public ulong ullTotalVirtual; //总计虚拟内存大小            public ulong ullAvailVirtual; //可用虚拟内存大小            public ulong ullAvailExtendedVirtual; //保留 这个值始终为0        }
