C#獲取用戶系統信息的程序

介紹

在這個程序當中，主要通過下面兩個類獲取用戶系統的信息：

1. System.Environment
2. System.Managememnt

應用程序包括三個tab菜單，分別是：

1. System
2. CPU
3. Local drives

程序外觀如下圖：

在 System 菜單中,用System.Environment 類來獲取系統信息 :

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 選項卡, 類System.Management用來收集信息,但是在使用該類之前需要加入引用. 加入System.Management引用的步驟如下:

1. 打開項目解決方案.
2. 右鍵單擊引用，選擇添加引用.
3. 單擊.NET 選項卡.
4. 選擇System.Management.
5. 單擊確定按鈕.

 現在可以用該類寫下面的函數:

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();
}

這個函數有一個參數，該參數的值可以是Win32_Processor 或Win32_LogicalDisk。用第一次參數來獲取CPU的信息，用第二參數來獲取硬盤驅動器的信息。最后再Window_Loaded函數中調用如下語句：

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