在.NET / C＃测试进程是否具有管理权限在.NET / C＃测试进程是否具有管理权限(In .N

有没有测试，看看是否该工艺具有计算机管理权限的规范呢？

我将要开始一个长期运行的进程，和许多在后面的过程一生它会尝试一些事情，需要管理员权限。

我希望能够测试前面如果进程有这些权利，而不是以后。

Answer 1:

这将检查用户是否是本地Administrators组中（假设你不检查域管理员权限）

using System.Security.Principal;

public bool IsUserAdministrator()
{
    //bool value to hold our return value
    bool isAdmin;
    WindowsIdentity user = null;
    try
    {
        //get the currently logged in user
        user = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(user);
        isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
    catch (UnauthorizedAccessException ex)
    {
        isAdmin = false;
    }
    catch (Exception ex)
    {
        isAdmin = false;
    }
    finally
    {
        if (user != null)
            user.Dispose();
    }
    return isAdmin;
}

与Wadih M的代码开始，我已经得到了一些额外的P / Invoke的代码，试图处理当UAC是开的情况下。

http://www.davidmoore.info/blog/2011/06/20/how-to-check-if-the-current-user-is-an-administrator-even-if-uac-is-on/

首先，我们需要一些代码来支持GetTokenInformation API调用：

[DllImport("advapi32.dll", SetLastError = true)]
static extern bool GetTokenInformation(IntPtr tokenHandle, TokenInformationClass tokenInformationClass, IntPtr tokenInformation, int tokenInformationLength, out int returnLength);

/// <summary>
/// Passed to <see cref="GetTokenInformation"/> to specify what
/// information about the token to return.
/// </summary>
enum TokenInformationClass
{
     TokenUser = 1,
     TokenGroups,
     TokenPrivileges,
     TokenOwner,
     TokenPrimaryGroup,
     TokenDefaultDacl,
     TokenSource,
     TokenType,
     TokenImpersonationLevel,
     TokenStatistics,
     TokenRestrictedSids,
     TokenSessionId,
     TokenGroupsAndPrivileges,
     TokenSessionReference,
     TokenSandBoxInert,
     TokenAuditPolicy,
     TokenOrigin,
     TokenElevationType,
     TokenLinkedToken,
     TokenElevation,
     TokenHasRestrictions,
     TokenAccessInformation,
     TokenVirtualizationAllowed,
     TokenVirtualizationEnabled,
     TokenIntegrityLevel,
     TokenUiAccess,
     TokenMandatoryPolicy,
     TokenLogonSid,
     MaxTokenInfoClass
}

/// <summary>
/// The elevation type for a user token.
/// </summary>
enum TokenElevationType
{
    TokenElevationTypeDefault = 1,
    TokenElevationTypeFull,
    TokenElevationTypeLimited
}

然后，实际的代码来检测，如果用户是管理员（如果他们返回true，否则为false）。

var identity = WindowsIdentity.GetCurrent();
if (identity == null) throw new InvalidOperationException("Couldn't get the current user identity");
var principal = new WindowsPrincipal(identity);

// Check if this user has the Administrator role. If they do, return immediately.
// If UAC is on, and the process is not elevated, then this will actually return false.
if (principal.IsInRole(WindowsBuiltInRole.Administrator)) return true;

// If we're not running in Vista onwards, we don't have to worry about checking for UAC.
if (Environment.OSVersion.Platform != PlatformID.Win32NT || Environment.OSVersion.Version.Major < 6)
{
     // Operating system does not support UAC; skipping elevation check.
     return false;
}

int tokenInfLength = Marshal.SizeOf(typeof(int));
IntPtr tokenInformation = Marshal.AllocHGlobal(tokenInfLength);

try
{
    var token = identity.Token;
    var result = GetTokenInformation(token, TokenInformationClass.TokenElevationType, tokenInformation, tokenInfLength, out tokenInfLength);

    if (!result)
    {
        var exception = Marshal.GetExceptionForHR( Marshal.GetHRForLastWin32Error() );
        throw new InvalidOperationException("Couldn't get token information", exception);
    }

    var elevationType = (TokenElevationType)Marshal.ReadInt32(tokenInformation);

    switch (elevationType)
    {
        case TokenElevationType.TokenElevationTypeDefault:
            // TokenElevationTypeDefault - User is not using a split token, so they cannot elevate.
            return false;
        case TokenElevationType.TokenElevationTypeFull:
            // TokenElevationTypeFull - User has a split token, and the process is running elevated. Assuming they're an administrator.
            return true;
        case TokenElevationType.TokenElevationTypeLimited:
            // TokenElevationTypeLimited - User has a split token, but the process is not running elevated. Assuming they're an administrator.
            return true;
        default:
            // Unknown token elevation type.
            return false;
     }
}
finally
{    
    if (tokenInformation != IntPtr.Zero) Marshal.FreeHGlobal(tokenInformation);
}

Answer 3:

如果你想确保你的解决方案在Vista UAC的作品，并有.NET Framework 3.5或更好的，你可能想使用System.DirectoryServices.AccountManagement命名空间。 您的代码看起来是这样的：

bool isAllowed = false;
using (PrincipalContext pc = new PrincipalContext(ContextType.Machine, null))
{
    UserPrincipal up = UserPrincipal.Current;
    GroupPrincipal gp = GroupPrincipal.FindByIdentity(pc, "Administrators");
    if (up.IsMemberOf(gp))
        isAllowed = true;
}

Answer 4:

试图欧文的代码，但它并没有编译。

心动不如行动，以这样的工作：

[DllImport("shell32.dll")] public static extern bool IsUserAnAdmin();

Answer 5:

使用.NET Framework 4.5，它似乎更容易检查，如果用户是管理员组：

WindowsPrincipal principal = WindowsPrincipal.Current;
bool canBeAdmin = principal.Claims.Any((c) => c.Value == "S-1-5-32-544");

Answer 6:

借力IsInRole方法其他答案只有当用户与提升令牌运行返回true，正如其他人的评论。 下面是只是在一个标准和高温情况下本地Administrators组成员身份检查潜在的替代品：

bool isAdmin = false;
using (var user = WindowsIdentity.GetCurrent())
{
    var principal = new WindowsPrincipal(user);
    // Check for token claim with well-known Administrators group SID
    const string LOCAL_ADMININSTRATORS_GROUP_SID = "S-1-5-32-544";
    if (principal.Claims.SingleOrDefault(x => x.Value == LOCAL_ADMININSTRATORS_GROUP_SID) != null)
    {
        isAdmin = true;
    }
}

return isAdmin;

Answer 7:

使用可以使用WMI像这样的东西，以找出是否该帐户是管理员，和其它任何东西，你想知道有帐户

using System;
using System.Management;
using System.Windows.Forms;

namespace WMISample
{
    public class MyWMIQuery
    {
        public static void Main()
        {
            try
            {
                ManagementObjectSearcher searcher = 
                    new ManagementObjectSearcher("root\\CIMV2", 
                    "SELECT * FROM Win32_UserAccount"); 

                foreach (ManagementObject queryObj in searcher.Get())
                {
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("Win32_UserAccount instance");
                    Console.WriteLine("-----------------------------------");
                    Console.WriteLine("AccountType: {0}", queryObj["AccountType"]);
                    Console.WriteLine("FullName: {0}", queryObj["FullName"]);
                    Console.WriteLine("Name: {0}", queryObj["Name"]);
                }
            }
            catch (ManagementException e)
            {
                MessageBox.Show("An error occurred while querying for WMI data: " + e.Message);
            }
        }
    }
}

你也可以使用这个它的访问活动目录（LDAP）或其他任何您的计算机/网络

关于什么：

using System.Runtime.InteropServices;

internal static class Useful {
    [DllImport("shell32.dll", EntryPoint = "IsUserAnAdmin")]
    public static extern bool IsUserAnAdministrator();
}

Answer 9:

有4个可能的方法 - 我喜欢：

(new WindowsPrincipal(WindowsIdentity.GetCurrent())).IsInRole(WindowsBuiltInRole.Administrator);

这里是代码给你所有相关索赔数据列表是当前的用户的身份。

注意：有beween索赔清单一个很大的区别是WindowsPrincipal.Current .Claims和（新WindowsPrincipal（WindowsIdentity.GetCurrent（）））.Claims之间返回

Console.WriteLine("press the ENTER key to start listing user claims:");
Console.ReadLine();

Console.WriteLine("---------------------");
