如何使用.NET远程扩展环境变量？

Question

我需要一种方法来扩展远程机器上的环境变量.

假设我有一个文件夹的路径,%appdata%\MyApp\Plugins或者%ProgramFiles%\MyCompany\MyApp\Plugins我想列出该文件夹中的文件以进行审计.唯一的问题是我想在远程计算机上执行此操作,但我有管理员访问权限.

一个额外的问题(但不是必不可少的)是如何为远程机器上的给定用户执行此操作？

Answer 1

您将使用GetFolderPath.您可以使用许多不同的SpecialFolder值,包括ProgramFiles和ApplicationData

string path = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles);

然后你可以把它与你的其他路径结合起来

string full_path = Path.Combine(path, "\MyApp\Plugins");

在远程计算机上,它看起来像你可以尝试像这样

ConnectionOptions co = new ConnectionOptions();
// user with sufficient privileges to connect to the cimv2 namespace
co.Username = "administrator"; 
// his password
co.Password = "adminPwd";
ManagementScope scope = new ManagementScope(@"\\BOBSMachine\root\cimv2", co);
SelectQuery query = new SelectQuery("Select windowsdirectory from Win32_OperatingSystem");
ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);
foreach (ManagementObject windir in searcher.Get())
   Console.WriteLine("Value = {0}", windir["windowsdirectory"]);

或者从这里获取所有远程环境变量及其值的列表

public static void GetSysInfo(string domain, string machine, string username, string password)
{
    ManagementObjectSearcher query = null;
    ManagementObjectCollection queryCollection = null;

    ConnectionOptions opt = new ConnectionOptions(); 

    opt.Impersonation = ImpersonationLevel.Impersonate; 
    opt.EnablePrivileges = true; 
    opt.Username = username; 
    opt.Password = password; 
    try 
    { 
        ManagementPath p = new ManagementPath("\\\\" +machine+ "\\root\\cimv2");   

        ManagementScope msc = new ManagementScope(p, opt); 

        SelectQuery q= new SelectQuery("Win32_Environment");

        query = new ManagementObjectSearcher(msc, q, null); 
        queryCollection = query.Get(); 

        Console.WriteLine(queryCollection.Count);

        foreach (ManagementBaseObject envVar in queryCollection) 
        {
            Console.WriteLine("System environment variable {0} = {1}", 
            envVar["Name"], envVar["VariableValue"]);
        }
    } 
    catch(ManagementException e) 
    { 
        Console.WriteLine(e.Message); 
        Environment.Exit(1); 
    } 
    catch(System.UnauthorizedAccessException e) 
    { 
        Console.WriteLine(e.Message); 
        Environment.Exit(1); 
    } 
}

OP编辑: 也%AppData%可以从注册表(可以远程进行)中找到HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders和程序文件的HKLM\Software\Microsoft\Windows\CurrentVersion下ProgramfilesDir.
