无法执行命令

我有一个dism.exe命令在Windows Server 2008上安装IIS，我试图以编程方式执行该命令。无法执行命令

 Console.WriteLine("Installing IIS..."); 
     if (File.Exists("iis.cmd")) 
      File.Delete("iis.cmd"); 


     using (StreamWriter sw = File.CreateText("iis.cmd")) 
     { sw.WriteLine(@"START /WAIT DISM /Online /Enable-Feature /FeatureName:IIS-ApplicationDevelopment /FeatureName:IIS-ASP /FeatureName:IIS-ASPNET /FeatureName:IIS-BasicAuthentication /FeatureName:IIS-CGI /FeatureName:IIS-ClientCertificateMappingAuthentication /FeatureName:IIS-CommonHttpFeatures /FeatureName:IIS-CustomLogging /FeatureName:IIS-DefaultDocument /FeatureName:IIS-DigestAuthentication /FeatureName:IIS-DirectoryBrowsing /FeatureName:IIS-FTPExtensibility /FeatureName:IIS-FTPServer /FeatureName:IIS-FTPSvc /FeatureName:IIS-HealthAndDiagnostics /FeatureName:IIS-HostableWebCore /FeatureName:IIS-HttpCompressionDynamic /FeatureName:IIS-HttpCompressionStatic /FeatureName:IIS-HttpErrors /FeatureName:IIS-HttpLogging /FeatureName:IIS-HttpRedirect /FeatureName:IIS-HttpTracing /FeatureName:IIS-IIS6ManagementCompatibility /FeatureName:IIS-IISCertificateMappingAuthentication /FeatureName:IIS-IPSecurity /FeatureName:IIS-ISAPIExtensions /FeatureName:IIS-ISAPIFilter /FeatureName:IIS-LegacyScripts /FeatureName:IIS-LegacySnapIn /FeatureName:IIS-LoggingLibraries /FeatureName:IIS-ManagementConsole /FeatureName:IIS-ManagementScriptingTools /FeatureName:IIS-ManagementService /FeatureName:IIS-Metabase /FeatureName:IIS-NetFxExtensibility /FeatureName:IIS-ODBCLogging /FeatureName:IIS-Performance /FeatureName:IIS-RequestFiltering /FeatureName:IIS-RequestMonitor /FeatureName:IIS-Security /FeatureName:IIS-ServerSideIncludes /FeatureName:IIS-StaticContent /FeatureName:IIS-URLAuthorization /FeatureName:IIS-WebDAV /FeatureName:IIS-WebServer /FeatureName:IIS-WebServerManagementTools /FeatureName:IIS-WebServerRole /FeatureName:IIS-WindowsAuthentication /FeatureName:IIS-WMICompatibility /FeatureName:WAS-ConfigurationAPI /FeatureName:WAS-NetFxEnvironment /FeatureName:WAS-ProcessModel /FeatureName:WAS-WindowsActivationService"); } 
     File.SetAttributes("iis.cmd", FileAttributes.Hidden); 

     ProcessStartInfo psi = new ProcessStartInfo(@"iis.cmd") 
      { 
       UseShellExecute = false, 
       RedirectStandardOutput = true, 
       RedirectStandardError = true 
      }; 
     Process pro = Process.Start(psi); 
     pro.WaitForExit(); 

     if (File.Exists("iis.cmd")) 
      File.Delete("iis.cmd"); 

     Console.WriteLine("IIS is installed"); 
     Console.WriteLine("Exiting..."); 
     Thread.Sleep(5000);

问题是此代码无法安装IIS。我可以看到一个空白的窗口并立即消失。当我手动打开cmd文件时，该命令运行正常，安装IIS。

编辑： 我只是试过下面的改变，它仍然无法正常工作！我能看到的只有一个空白窗口（dism.exe）弹出窗口，并以秒为单位完成。

我想你错过了'.Flush（）'部分。尝试在'WriteLine'之后添加'sw.Flush（）'。也许我只是错了，但试试看吧。当手动检查'iis.cmd'时命令是否正确？ – Kimmax

@Kimmax - yse，你只是错了 - 注意在代码中使用''。 –

我相信这可能与用户的权限/特权有关。也许你没有在高架模式下运行？ –

您正在尝试启动iis.cmd，就好像它是可执行文件一样。不是这样。

您需要启动cmd.exe命令解释器，并将它作为参数传递给iis.cmd。

ProcessStartInfo psi = new ProcessStartInfo("cmd.exe", "/C iis.cmd") 
{ 
    .... 
}

/C选项是让脚本结束时解释器终止。

如果您想要更加正确，您可以选择阅读COMSPEC环境变量而不是硬编码cmd.exe。

不是“.cmd”的一种可执行文件吗？从Windows + R运行时，Windows可以在没有cmd的情况下启动它们？ – Kimmax

@Kimmax一个.cmd文件在其中包含任何你在其中的内容。在这种情况下，提问者在其中放置文本。当你要求shell在默认情况下打开一个'.cmd'文件时，它会将它与命令解释器'cmd.exe'关联起来。但是由于'UseShellExecute = false'，shell在这里看不到。 –

这很有道理。谢谢！ – Kimmax

原来是dism.exe路径的问题。下面的代码工作：

if (File.Exists(@"C:\Windows\SysWOW64\dism.exe")) 
    sw.WriteLine(@"START /WAIT C:\Windows\SysWOW64\dism.exe /Online /Enable-Feature /FeatureName:IIS-ApplicationDevelopment /FeatureName:IIS-ASP /FeatureName:IIS-ASPNET /FeatureName:IIS-BasicAuthentication /FeatureName:IIS-CGI /FeatureName:IIS-ClientCertificateMappingAuthentication /FeatureName:IIS-CommonHttpFeatures /FeatureName:IIS-CustomLogging /FeatureName:IIS-DefaultDocument /FeatureName:IIS-DigestAuthentication /FeatureName:IIS-DirectoryBrowsing /FeatureName:IIS-FTPExtensibility /FeatureName:IIS-FTPServer /FeatureName:IIS-FTPSvc /FeatureName:IIS-HealthAndDiagnostics /FeatureName:IIS-HostableWebCore /FeatureName:IIS-HttpCompressionDynamic /FeatureName:IIS-HttpCompressionStatic /FeatureName:IIS-HttpErrors /FeatureName:IIS-HttpLogging /FeatureName:IIS-HttpRedirect /FeatureName:IIS-HttpTracing /FeatureName:IIS-IIS6ManagementCompatibility /FeatureName:IIS-IISCertificateMappingAuthentication /FeatureName:IIS-IPSecurity /FeatureName:IIS-ISAPIExtensions /FeatureName:IIS-ISAPIFilter /FeatureName:IIS-LegacyScripts /FeatureName:IIS-LegacySnapIn /FeatureName:IIS-LoggingLibraries /FeatureName:IIS-ManagementConsole /FeatureName:IIS-ManagementScriptingTools /FeatureName:IIS-ManagementService /FeatureName:IIS-Metabase /FeatureName:IIS-NetFxExtensibility /FeatureName:IIS-ODBCLogging /FeatureName:IIS-Performance /FeatureName:IIS-RequestFiltering /FeatureName:IIS-RequestMonitor /FeatureName:IIS-Security /FeatureName:IIS-ServerSideIncludes /FeatureName:IIS-StaticContent /FeatureName:IIS-URLAuthorization /FeatureName:IIS-WebDAV /FeatureName:IIS-WebServer /FeatureName:IIS-WebServerManagementTools /FeatureName:IIS-WebServerRole /FeatureName:IIS-WindowsAuthentication /FeatureName:IIS-WMICompatibility /FeatureName:WAS-ConfigurationAPI /FeatureName:WAS-NetFxEnvironment /FeatureName:WAS-ProcessModel /FeatureName:WAS-WindowsActivationService"); 
else if (File.Exists(@"C:\Windows\System32\dism.exe")) 
    sw.WriteLine(@"START /WAIT C:\Windows\System32\dism.exe /Online /Enable-Feature /FeatureName:IIS-ApplicationDevelopment /FeatureName:IIS-ASP /FeatureName:IIS-ASPNET /FeatureName:IIS-BasicAuthentication /FeatureName:IIS-CGI /FeatureName:IIS-ClientCertificateMappingAuthentication /FeatureName:IIS-CommonHttpFeatures /FeatureName:IIS-CustomLogging /FeatureName:IIS-DefaultDocument /FeatureName:IIS-DigestAuthentication /FeatureName:IIS-DirectoryBrowsing /FeatureName:IIS-FTPExtensibility /FeatureName:IIS-FTPServer /FeatureName:IIS-FTPSvc /FeatureName:IIS-HealthAndDiagnostics /FeatureName:IIS-HostableWebCore /FeatureName:IIS-HttpCompressionDynamic /FeatureName:IIS-HttpCompressionStatic /FeatureName:IIS-HttpErrors /FeatureName:IIS-HttpLogging /FeatureName:IIS-HttpRedirect /FeatureName:IIS-HttpTracing /FeatureName:IIS-IIS6ManagementCompatibility /FeatureName:IIS-IISCertificateMappingAuthentication /FeatureName:IIS-IPSecurity /FeatureName:IIS-ISAPIExtensions /FeatureName:IIS-ISAPIFilter /FeatureName:IIS-LegacyScripts /FeatureName:IIS-LegacySnapIn /FeatureName:IIS-LoggingLibraries /FeatureName:IIS-ManagementConsole /FeatureName:IIS-ManagementScriptingTools /FeatureName:IIS-ManagementService /FeatureName:IIS-Metabase /FeatureName:IIS-NetFxExtensibility /FeatureName:IIS-ODBCLogging /FeatureName:IIS-Performance /FeatureName:IIS-RequestFiltering /FeatureName:IIS-RequestMonitor /FeatureName:IIS-Security /FeatureName:IIS-ServerSideIncludes /FeatureName:IIS-StaticContent /FeatureName:IIS-URLAuthorization /FeatureName:IIS-WebDAV /FeatureName:IIS-WebServer /FeatureName:IIS-WebServerManagementTools /FeatureName:IIS-WebServerRole /FeatureName:IIS-WindowsAuthentication /FeatureName:IIS-WMICompatibility /FeatureName:WAS-ConfigurationAPI /FeatureName:WAS-NetFxEnvironment /FeatureName:WAS-ProcessModel /FeatureName:WAS-WindowsActivationService");
