ASP.. NET命令行问题

尝试使用模拟来执行该代码。下面是我为基于实例的编程模拟创建的一个类:

/// <summary>

/// </summary> 
public class ImpersonationContext : IDisposable 
{ 
    #region constants

    private const int LOGON32_PROVIDER_DEFAULT = 0; 
    #endregion 
    #region global variables 
    private WindowsImpersonationContext impersonationContext; 
    private bool impersonating; 
    #endregion 
    #region unmanaged code

    [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)] 
    private static extern int DuplicateToken(IntPtr hToken, int impersonationLevel, ref IntPtr hNewToken); 
    [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)] 
    private static extern bool RevertToSelf(); 
    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]

    #endregion

    public ImpersonationContext() 
    { 
        impersonating = false; 
    } 
    /// <summary>

    public void BeginImpersonationContext(string userName, string password, string domain) 
    { 
        //initialize token and duplicate variables 
        IntPtr token = IntPtr.Zero; 
        IntPtr tokenDuplicate = IntPtr.Zero;

            { 
                if (DuplicateToken(token, 2, ref tokenDuplicate) != 0) 
                { 
                    using (WindowsIdentity tempWindowsIdentity = new WindowsIdentity(tokenDuplicate)) 
                    { 
                        //begin the impersonation context and mark impersonating true 
                        impersonationContext = tempWindowsIdentity.Impersonate(); 
                        impersonating = true; 
                    } 
                } 
            } 
        }

        //close the handle to the duplicated account token 
        if (tokenDuplicate != IntPtr.Zero) 
            CloseHandle(tokenDuplicate); 
    } 
    /// <summary>

    public void EndImpersonationContext() 
    { 
        //if the context exists undo it and dispose of the object

        {

            impersonationContext.Dispose(); 
        } 
        //mark the impersonation flag false 
        impersonating = false; 
    } 
    #endregion

        get

            return impersonating; 
        } 
    } 
    #endregion

    { 
        if (disposing) 
        { 
            if (impersonationContext != null) 
            { 
                impersonationContext.Undo(); 
                impersonationContext.Dispose(); 
            } 
        } 
    } 
    #endregion     
} 

下面是如何实现它的一个例子:

using (ImpersonationContext context = new ImpersonationContext("user", "password", "domain")) 
{ 
    if (context.Impersonating) 
    { 
        ProcessStartInfo processStartInfo =  new ProcessStartInfo("cmd.exe");   
        processStartInfo.RedirectStandardInput = true;   
        processStartInfo.RedirectStandardOutput = true;   
        processStartInfo.UseShellExecute = false;   
        Process process = Process.Start(processStartInfo);      
        if (process != null)   
        {   
            process.StandardInput.WriteLine("dir");   
            process.StandardInput.WriteLine("md test123");   
        }  
    } 
}
