如何在不使用Shell在64位计算机上执行的情况下在C＃中启动32位进程？ [英] How to start a 32-bit process in C# without using shell execute on 64-bit machine?

问题描述

我在64位计算机上有一个ASP .NET Web应用程序，需要运行旧的32位报表应用程序。

I have an ASP .NET web application on a 64-bit machine that needs to run a legacy 32-bit reporting application.

UseShellExecute = false ，程序退出并退出代码：

When I run the program with UseShellExecute = false, the program exits with exit code:

-1073741502

我不能使用Shell Execute，因为我必须以其他用户身份运行该进程。但是，当Shell Execute为true时，该过程将运行正常（尽管我必须更改正在执行ASP .NET的用户）。

I can't use Shell Execute because I have to run the process as a different user. Yet, when Shell Execute is true, the process will run fine (although I have to change the user that ASP .NET is executing under).

如何启动此功能

这是我现在拥有的代码：

Here's the code I have right now:

var pxs = new ProcessStartInfo
{
    Arguments = arguments,
    CreateNoWindow = true,
    Domain = ConfigurationManager.AppSettings["reportUserDomain"],
    UserName = ConfigurationManager.AppSettings["reportUserName"],
    Password = GetSecureString(ConfigurationManager.AppSettings["reportUserPassword"]),
    LoadUserProfile = true,
    FileName = ConfigurationManager.AppSettings["reportRuntime"],
    UseShellExecute = false             

};

var px = new Process
{
    StartInfo = pxs
};

px.Start();
px.WaitForExit();

推荐答案

如果包围了代码，包括 UseShellExecute = true ，使用Windows本机 LogonUser方法？我已经在一些项目中成功地使用了它来做 like 。

What if you surrounded your code, including UseShellExecute = true, with the windows native "LogonUser" method? I've used this successfully in a few projects to do something similar.

[DllImport("advapi32.dll", CharSet = CharSet.Auto)]
public static extern bool LogonUser(String lpszUserName, String lpszDomain,
    String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken

Fresh Click Media对此做了一篇文章，并编写了一个示例的Impersonate类：-> http://www.freshclickmedia.com/blog/2008/11/programmatic-impersonation-in-c /

Fresh Click Media did an article about this and wrote a sample Impersonate class: --> http://www.freshclickmedia.com/blog/2008/11/programmatic-impersonation-in-c/

但是为了完整起见，这是我的版本：

But for completeness, here's my version of it:

public class Impersonator : IDisposable
{
    private WindowsImpersonationContext _impersonatedUser = null;
    private IntPtr _userHandle;

    // constructor for a local account. username and password are arguments.
    public Impersonator(string username, string passwd)
    {
        _userHandle = new IntPtr(0);

        string user = username;
        string userDomain = "."; // The domain for a local user is by default "."
        string password = passwd;

        bool returnValue = LogonUser(user, userDomain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref _userHandle);

        if (!returnValue)
            throw new ApplicationException("Could not impersonate user");

        WindowsIdentity newId = new WindowsIdentity(_userHandle);
        _impersonatedUser = newId.Impersonate();
    }

    // constructor where username, password and domain are passed as parameters
    public Impersonator(string username, string passwd, string domain)
    {
        _userHandle = new IntPtr(0);

        string user = username;
        string userDomain = domain;
        string password = passwd;

        bool returnValue = LogonUser(user, userDomain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref _userHandle);

        if (!returnValue)
            throw new ApplicationException("Could not impersonate user");

        WindowsIdentity newId = new WindowsIdentity(_userHandle);
        _impersonatedUser = newId.Impersonate();
    }

    public void Dispose()
    {
        if (_impersonatedUser != null)
        {
            _impersonatedUser.Undo();
            CloseHandle(_userHandle);
        }
    }

    public const int LOGON32_LOGON_INTERACTIVE = 2;
    public const int LOGON32_LOGON_SERVICE = 3;
    public const int LOGON32_PROVIDER_DEFAULT = 0;

    [DllImport("advapi32.dll", CharSet = CharSet.Auto)]
    public static extern bool LogonUser(String lpszUserName, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);

    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
    public extern static bool CloseHandle(IntPtr handle);
}

在您的情况下使用的是：

Using it in your case would be:

var domain = ConfigurationManager.AppSettings["reportUserDomain"];
var username = ConfigurationManager.AppSettings["reportUserName"];
var password = ConfigurationManager.AppSettings["reportUserPassword"];

using (Impersonator impersonator = new Impersonator(username, password, domain))
{
    var pxs = new ProcessStartInfo
    {
        Arguments = arguments,
        CreateNoWindow = true,
        LoadUserProfile = true,
        FileName = ConfigurationManager.AppSettings["reportRuntime"],
        UseShellExecute = true
    };

    var px = new Process
    {
        StartInfo = pxs
    };

    px.Start();
    px.WaitForExit();
}
