先秀下效果图。要获取主机信息包括：OS名称、版本、OS 制造商、系统名称、Windows 目录、系统目录、启动设备、区域设置、时区、总的物理内存、可用物理内存、总的虚拟内存、可用虚拟内存和页面文件空间。
本系统计划采用如下的结构（懒得画图，直接用语言描述）：一个类库，用于获取计算机的信息。解决方案命名为：ComputerInfo，里面包含一些类，以后每个小功能都会增加一个类，现在刚刚做了获取计算机的信息的类，命名为：SystemInfo，类图如下。然后每个小功能为一个解决方案里面的一个窗体。
public class SystemInfo
{
属性#region 属性 OS名称#region OS名称
string strOSName = string.Empty; //OS名称 public string OSName { get { return strOSName; } set { strOSName = value; }
} #endregion OS版本#region OS版本 string strOSVersion = string.Empty; //OS版本 public string OSVersion { get { return strOSVersion; } set { strOSVersion = value; } } #endregion OS制造商#region OS制造商 string strOSManufacturer = string.Empty; //OS制造商 public string OSManufacturer { get { return strOSManufacturer; } set { strOSManufacturer = value; } } #endregion Windows 目录#region Windows 目录 string strWindowsDirectory = string.Empty; public string WindowsDirectory { get { return strWindowsDirectory; } set { strWindowsDirectory = value; } } #endregion 系统目录#region 系统目录 string strSystemDirectory = string.Empty; //系统目录 public string SystemDirectory { get { return strSystemDirectory; } set { strSystemDirectory = value; } } #endregion 启动设备#region 启动设备 string strBootDevice = string.Empty; //启动设备 public string BootDevice { get { return strBootDevice; } set { strBootDevice = value; } } #endregion 地区#region 地区 string strCountry = string.Empty; //地区 public string Country { get { return strCountry; } set { strCountry = value; } } #endregion 时区#region 时区 string strTimeZone = string.Empty; //时区 public string TimeZone { get { return strTimeZone; } set { strTimeZone = value; } } #endregion 总的物理内存#region 总的物理内存 string strTotalVisibleMemorySize = string.Empty; //总的物理内存 public string TotalVisibleMemorySize { get { return strTotalVisibleMemorySize; } set { strTotalVisibleMemorySize = value; } } #endregion 可用物理内存#region 可用物理内存 string strFreePhysicalMemory = string.Empty; //可用物理内存 public string FreePhysicalMemory { get { return strFreePhysicalMemory; } set { strFreePhysicalMemory = value; } } #endregion 总的虚拟内存#region 总的虚拟内存 string strTotalVirtualMemorySize = string.Empty; //总的虚拟内存 public string TotalVirtualMemorySize { get { return strTotalVirtualMemorySize; } set { strTotalVirtualMemorySize = value; } } #endregion 可用虚拟内存#region 可用虚拟内存 string strFreeVirtualMemory = string.Empty; //可用虚拟内存 public string FreeVirtualMemory { get { return strFreeVirtualMemory; } set { strFreeVirtualMemory = value; } } #endregion 页面文件大小#region 页面文件大小 string strSizeStoredInPagingFiles = string.Empty; //页面文件大小 public string SizeStoredInPagingFiles { get { return strSizeStoredInPagingFiles; } set { strSizeStoredInPagingFiles = value; } } #endregion #endregion 构造函数#region 构造函数 public SystemInfo() { GetSystemInfo(); } #endregion GetSystemInfo#region GetSystemInfo private void GetSystemInfo() { OSVersion = Environment.OSVersion.ToString(); //通过系统自带的Environment这个类来获取 系统的版本 SystemName = Environment.MachineName; //通过系统自带的Environment这个类来获取 系统的名称 Country = System.Globalization.CultureInfo.CurrentCulture.DisplayName; //获取区域设置 TimeZone = System.TimeZone.CurrentTimeZone.StandardName; //获取时区设置 //实例化一个ManagementClass类，并将Win32_OperatingSystem作为参数传递进去， //这样就可以查询Win32_OperatingSystem这个类里面的一些信息了。 ManagementClass mClass = new ManagementClass("Win32_OperatingSystem"); //获取Win32_OperatingSystem这个类的所有实例 ManagementObjectCollection moCollection = mClass.GetInstances(); //对Win32_OperatingSystem这个类进行遍历 foreach (ManagementObject mObject in moCollection) { OSName = mObject["Caption"].ToString(); //获取OS 名称 OSManufacturer = mObject["Manufacturer"].ToString(); //获取 OS 制造商 SystemName = mObject["CSName"].ToString(); //获取系统名称 WindowsDirectory = mObject["WindowsDirectory"].ToString(); //获取Windows 目录 SystemDirectory = mObject["SystemDirectory"].ToString(); //获取系统目录 BootDevice = mObject["BootDevice"].ToString(); //获取启动设备 TotalVisibleMemorySize = ((ulong)mObject["TotalVisibleMemorySize"] / 1024.0 / 1024).ToString("#0.00") + "G"; //获取总的物理内存 FreePhysicalMemory = ((ulong)mObject["FreePhysicalMemory"] / 1024.0 / 1024).ToString("#0.00") + "G"; //获取可用物理内存 TotalVirtualMemorySize = ((ulong)mObject["TotalVirtualMemorySize"] / 1024.0 / 1024).ToString("#0.00") + "G"; //获取总的虚拟内存 FreeVirtualMemory = ((ulong)mObject["FreeVirtualMemory"] / 1024.0 / 1024).ToString("#0.00") + "G"; //获取可用虚拟内存 SizeStoredInPagingFiles = ((ulong)mObject["SizeStoredInPagingFiles"] / 1024.0 / 1024).ToString("#0.00") + "G"; //获取页面文件大小 } } #endregion
}
再启动一个VS2008 创建一个解决方案命名为：HostPerformance，添加上面那个类库的引用，如下图
添加一个窗体，命名为：SystemInfoForm，往窗体里面添加一个ListView控件，代码如下：
SystemInfo Form public partial class SystemInfoForm : Form { public SystemInfoForm() { InitializeComponent(); } private void SystemInfoForm_Load(object sender, EventArgs e) { //实例化一个ComputerInfo.SystemInfo类。 ComputerInfo.SystemInfo systemInfo = new ComputerInfo.SystemInfo(); 定义一些需要用到的项#region 定义一些需要用到的项 ListViewItem lviOSName = new ListViewItem(new string[]{ "OS 名称",systemInfo.OSName}); ListViewItem lviOSVersion = new ListViewItem(new string[] { "版本", systemInfo.OSVersion }); ListViewItem lviOSManufacturer = new ListViewItem(new string[] { "OS 制造商", systemInfo.OSManufacturer }); ListViewItem lviSystemName = new ListViewItem(new string[] { "系统名称", systemInfo.SystemName }); ListViewItem lviWindowsDirectory = new ListViewItem(new string[] { "Windows 目录", systemInfo.WindowsDirectory }); ListViewItem lviSystemDirectory = new ListViewItem(new string[] { "系统目录", systemInfo.SystemDirectory }); ListViewItem lviBootDevice = new ListViewItem(new string[] { "启动设备", systemInfo.BootDevice }); ListViewItem lviCountry = new ListViewItem(new string[] { "区域设置", systemInfo.Country }); ListViewItem lviTimeZone = new ListViewItem(new string[] { "时区", systemInfo.TimeZone }); ListViewItem lviTotalVisibleMemorySize = new ListViewItem(new string[] { "总的物理内存", systemInfo.TotalVisibleMemorySize }); ListViewItem lviFreePhysicalMemory = new ListViewItem(new string[] { "可用物理内存", systemInfo.FreePhysicalMemory }); ListViewItem lviTotalVirtualMemorySize = new ListViewItem(new string[] { "总的虚拟内存", systemInfo.TotalVirtualMemorySize }); ListViewItem lviFreeVirtualMemory = new ListViewItem(new string[] { "可用虚拟内存", systemInfo.FreeVirtualMemory }); ListViewItem lviSizeStoredInPagingFiles = new ListViewItem(new string[] { "页面文件空间", systemInfo.SizeStoredInPagingFiles }); #endregion 将项添加到ListView控件里面#region 将项添加到ListView控件里面 lvHostInformation.Items.Add(lviOSName); lvHostInformation.Items.Add(lviOSVersion); lvHostInformation.Items.Add(lviOSManufacturer); lvHostInformation.Items.Add(lviSystemName); lvHostInformation.Items.Add(lviWindowsDirectory); lvHostInformation.Items.Add(lviSystemDirectory); lvHostInformation.Items.Add(lviBootDevice); lvHostInformation.Items.Add(lviCountry); lvHostInformation.Items.Add(lviTimeZone); lvHostInformation.Items.Add(lviTotalVisibleMemorySize); lvHostInformation.Items.Add(lviFreePhysicalMemory); lvHostInformation.Items.Add(lviTotalVirtualMemorySize); lvHostInformation.Items.Add(lviFreeVirtualMemory); lvHostInformation.Items.Add(lviSizeStoredInPagingFiles); #endregion 设置ListView的样式以及列#region 设置ListView的样式以及列 lvHostInformation.View = View.Details; lvHostInformation.Columns.Add("项",150); lvHostInformation.Columns.Add("值",300); lvHostInformation.FullRowSelect = true; lvHostInformation.GridLines = true; #endregion } }至此，获取计算机信息的小功能就做完了，代码都已经贴上来了，大家可以自己弄到VS2008里面试试。
未完，待续~~下期预告：2.获取性能信息--CPU
