C#獲取用戶系統信息的程序

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：

System.Environment
System.Managememnt
應用程序包括三個tab菜單，分別是：

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

[csharp]
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:

打開項目解決方案.
右鍵單擊引用，選擇添加引用.
單擊.NET 選項卡.
選擇System.Management.
單擊確定按鈕.
 現在可以用該類寫下面的函數:

[csharp]
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。最後再Window_Loaded函數中調用如下語句：

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