我想从我们的asp.net代码(命令行参数)执行一些ms dos命令。但系统不允许这个(Windows 2008服务器)。任何帮助都会很棒。相同的代码在我们的Windows 2003服务器上正常工作。请参阅下面我使用的代码。ASP.NET命令行问题

protected void btn_Click(object sender, EventArgs e) 
{ 
    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"); 
    } 
}

可以定义*“系统不允许这种” *? – slugster

这有点安全风险,您需要为应用程序池用户授予可执行目录的权限。你最好在Web应用程序目录下的某个地方放置一个批处理文件,然后给AppPool权限执行它。 – TheCodeKing

如果dir和md 是您所做的一切,那么您为什么不使用System.IO命名空间?我会尽可能长时间地走这条路,只有在功能无法使用可编程的可用方式时才使用不同的方法。 – Sascha

尝试使用模拟来执行该代码。下面是我基于实例的可编程的模拟创建了一个类:

/// <summary> 
/// Leverages the Windows API (advapi32.dll) to programmatically impersonate a user. 
/// </summary> 
public class ImpersonationContext : IDisposable 
{ 
    #region constants 

    private const int LOGON32_LOGON_INTERACTIVE = 2; 
    private const int LOGON32_PROVIDER_DEFAULT = 0; 

    #endregion 

    #region global variables 

    private WindowsImpersonationContext impersonationContext; 
    private bool impersonating; 

    #endregion 

    #region unmanaged code 

    [DllImport("advapi32.dll")] 
    private static extern int LogonUserA(String lpszUserName, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); 

    [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)] 
    private static extern bool CloseHandle(IntPtr handle); 

    #endregion 

    #region constructors 

    public ImpersonationContext() 
    { 
     impersonating = false; 
    } 

    /// <summary> 
    /// Overloaded constructor and begins impersonating. 
    /// </summary> 
    public ImpersonationContext(string userName, string password, string domain) 
    { 
     this.BeginImpersonationContext(userName, password, domain); 
    } 

    #endregion 

    #region impersonation methods 

    /// <summary> 
    /// Begins the impersonation context for the specified user. 
    /// </summary> 
    /// <remarks>Don't call this method if you used the overloaded constructor.</remarks> 
    public void BeginImpersonationContext(string userName, string password, string domain) 
    { 
     //initialize token and duplicate variables 
     IntPtr token = IntPtr.Zero; 
     IntPtr tokenDuplicate = IntPtr.Zero; 

     if (RevertToSelf()) 
     { 
      if (LogonUserA(userName, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token) != 0) 
      { 
       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 account token 
     if (token != IntPtr.Zero) 
      CloseHandle(token); 

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

    /// <summary> 
    /// Ends the current impersonation context. 
    /// </summary> 
    public void EndImpersonationContext() 
    { 
     //if the context exists undo it and dispose of the object 
     if (impersonationContext != null) 
     { 
      //end the impersonation context and dispose of the object 
      impersonationContext.Undo(); 
      impersonationContext.Dispose(); 
     } 

     //mark the impersonation flag false 
     impersonating = false; 
    } 

    #endregion 

    #region properties 

    /// <summary> 
    /// Gets a value indicating whether the impersonation is currently active. 
    /// </summary> 
    public bool Impersonating 
    { 
     get 
     { 
      return impersonating; 
     } 
    } 

    #endregion 

    #region IDisposable implementation 

    ~ImpersonationContext() 
    { 
     Dispose(false); 
    } 

    public void Dispose() 
    { 
     Dispose(true);     
    } 

    protected virtual void Dispose(bool disposing) 
    { 
     if (disposing) 
     { 
      if (impersonationContext != null) 
      { 
       impersonationContext.Undo(); 
       impersonationContext.Dispose(); 
      } 
     } 
    } 

    #endregion  
} 

这里是如何执行的一个例子:

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"); 
     } 
    } 
}
