[C#] 獲取作業系統環境參數

whitefox

這裡使用微軟內建的 Environment 類別來獲取相關環境參數

1. //--------------獲取當前程序信息
   
2. //當前程序啟動的命令，字符串
   
3. Console.WriteLine("CommandLine:{0}", Environment.CommandLine);
   
4. string[] arguments = Environment.GetCommandLineArgs();
   
5. Console.WriteLine("GetCommandLineArgs:{0}", string.Join(", ", arguments));
   
6. //獲取當前程序目錄
   
7. Console.WriteLine("CurrentDirectory:{0}", Environment.CurrentDirectory);
   
8. //獲取當前程序，工作的物理內存大小
   
9. Console.WriteLine("WorkingSet: {0}", Environment.WorkingSet);
   
10. //退出碼
    
11. Console.WriteLine("ExitCode:{0}", Environment.ExitCode);
    
12. //獲取當前程序是否開機啟動
    
13. Console.WriteLine("HasShutdownStarted: {0}", Environment.HasShutdownStarted);
    
14. //獲取當前追蹤信息
    
15. Console.WriteLine("StackTrace: '{0}'", Environment.StackTrace);
    
16. //獲取換行符
    
17. Console.WriteLine("NewLine: {0}  first line{0}  second line{0}  third line", Environment.NewLine);
    
18. 
    
19. //--------------獲取當前用戶資訊
    
20. //當前用戶的域名稱
    
21. Console.WriteLine("UserDomainName: {0}", Environment.UserDomainName);
    
22. //當前用戶是否交互
    
23. Console.WriteLine("UserInteractive: {0}", Environment.UserInteractive);
    
24. //當前用戶名稱
    
25. Console.WriteLine("UserName: {0}", Environment.UserName);
    
26. 
    
27. //--------------獲取當前系統資訊
    
28. //獲取當前計算機名稱
    
29. Console.WriteLine("MachineName: {0}", Environment.MachineName);
    
30. //獲取系統鏡像等版本
    
31. Console.WriteLine("Version: {0}", Environment.Version.ToString());
    
32. //獲取當前操作系統版本
    
33. Console.WriteLine("OSVersion: {0}", Environment.OSVersion.ToString());
    
34. //獲取當前系統目錄
    
35. Console.WriteLine("GetFolderPath: {0}",
    
36.                 Environment.GetFolderPath(Environment.SpecialFolder.System));
    
37. //獲取當前計算機邏輯磁盤名稱列表
    
38. String[] drives = Environment.GetLogicalDrives();
    
39. Console.WriteLine("GetLogicalDrives: {0}", String.Join(", ", drives));
    
40. //獲取系統目錄
    
41. String str;
    
42. String nl = Environment.NewLine;
    
43. String query = "My system drive is %SystemDrive% and my system root is %SystemRoot%";
    
44. str = Environment.ExpandEnvironmentVariables(query);
    
45. Console.WriteLine("ExpandEnvironmentVariables: {0}  {1}", nl, str);
    
46. //獲取系統臨時文件夾
    
47. Console.WriteLine("GetEnvironmentVariable: {0}  My temporary directory is {1}.", nl,
    
48.                         Environment.GetEnvironmentVariable("TEMP"));
    
49. 
    
50. //--------------遍歷所有資訊
    
51. Console.WriteLine("GetEnvironmentVariables: ");
    
52. IDictionary environmentVariables = Environment.GetEnvironmentVariables();
    
53. foreach (DictionaryEntry de in environmentVariables)
    
54. {
    
55.     Console.WriteLine("  {0} = {1}", de.Key, de.Value);
    
56. }
