C#获取用户系统信息的程序

介绍

在这个程序当中，主要通过下面两个类获取用户系统的信息：

1. System.Environment
2. System.Managememnt

应用程序包括三个tab菜单，分别是：

1. System
2. CPU
3. Local drives

程序外观如下图：

在 System 菜单中,用System.Environment 类来获取系统信息 :

private string SystemInformation()  {      StringBuilder StringBuilder1 = new StringBuilder(string.Empty);      try      {          StringBuilder1.AppendFormat("Operation System:  {0}\n", Environment.OSVersion);          if (Environment.Is64BitOperatingSystem)              StringBuilder1.AppendFormat("\t\t  64 Bit Operating System\n");          else              StringBuilder1.AppendFormat("\t\t  32 Bit Operating System\n");          StringBuilder1.AppendFormat("SystemDirectory:  {0}\n", Environment.SystemDirectory);          StringBuilder1.AppendFormat("ProcessorCount:  {0}\n", Environment.ProcessorCount);          StringBuilder1.AppendFormat("UserDomainName:  {0}\n", Environment.UserDomainName);          StringBuilder1.AppendFormat("UserName: {0}\n", Environment.UserName);          //Drives          StringBuilder1.AppendFormat("LogicalDrives:\n");          foreach (System.IO.DriveInfo DriveInfo1 in System.IO.DriveInfo.GetDrives())          {              try              {                  StringBuilder1.AppendFormat("\t Drive: {0}\n\t\t VolumeLabel: " +                     "{1}\n\t\t DriveType: {2}\n\t\t DriveFormat: {3}\n\t\t " +                     "TotalSize: {4}\n\t\t AvailableFreeSpace: {5}\n",                    DriveInfo1.Name, DriveInfo1.VolumeLabel, DriveInfo1.DriveType,                     DriveInfo1.DriveFormat, DriveInfo1.TotalSize, DriveInfo1.AvailableFreeSpace);              }              catch              {              }          }          StringBuilder1.AppendFormat("SystemPageSize:  {0}\n", Environment.SystemPageSize);          StringBuilder1.AppendFormat("Version:  {0}", Environment.Version);      }      catch      {      }      return StringBuilder1.ToString();  }

在 CPU 和 Local drive 选项卡, 类System.Management用来收集信息,但是在使用该类之前需要加入引用. 加入System.Management引用的步骤如下:

1. 打开项目解决方案.
2. 右键单击引用，选择添加引用.
3. 单击.NET 选项卡.
4. 选择System.Management.
5. 单击确定按钮.

 现在可以用该类写下面的函数:

private string DeviceInformation(string stringIn)  {      StringBuilder StringBuilder1 = new StringBuilder(string.Empty);      ManagementClass ManagementClass1 = new ManagementClass(stringIn);      //Create a ManagementObjectCollection to loop through      ManagementObjectCollection ManagemenobjCol = ManagementClass1.GetInstances();      //Get the properties in the class      PropertyDataCollection properties = ManagementClass1.Properties;      foreach (ManagementObject obj in ManagemenobjCol)      {          foreach (PropertyData property in properties)          {              try              {                  StringBuilder1.AppendLine(property.Name + ":  " +                     obj.Properties[property.Name].Value.ToString());              }              catch              {                  //Add codes to manage more informations              }          }          StringBuilder1.AppendLine();      }      return StringBuilder1.ToString();  }

这个函数有一个参数，该参数的值可以是Win32_Processor 或Win32_LogicalDisk。用第一次参数来获取CPU的信息，用第二参数来获取硬盘驱动器的信息。最后再Window_Loaded函数中调用如下语句：

//System Information  textBox1.Text = SystemInformation();  //CPU Information  textBox2.Text = DeviceInformation("Win32_Processor");  //Local Drives Information  textBox3.Text = DeviceInformation("Win32_LogicalDisk");
