在C#中运行bat文件会引发无法识别的错误

问题描述

我想通过bat文件在c#程序中添加一些DNS记录，所以我已经在bat文件中写了以下几行:

I wan to add some DNS records in c# program via a bat file so I have written these lines in bat file:

    set servername=%1
set siteaddress=%2


"C:\Windows\System32\dnscmd.exe" %servername% /zoneadd %siteaddress% /primary /file  %siteaddress%.dns

我已经用C#编写了这些行:

and I have written these lines in C#:

Process p = new Process();
                    p.StartInfo.UseShellExecute = false;
                    p.StartInfo.WorkingDirectory = Application.StartupPath;
                    p.StartInfo.FileName = General.DnsBatPath;
                    p.StartInfo.Arguments = string.Format("{0} {1}", General.DnsServerName, txtSiteAddress.Text);
                    p.Start();
                    p.WaitForExit();

我收到此错误"dnscmd.exe无法识别为内部或外部命令..."，但是当我手动运行bat文件时(在C#外部)，一切正常.

I get this error "dnscmd.exe is not recognized as internal or external command..." but when I run bat file manually (outside of C#) all things are OK.

我更改了C#代码以检查发生了什么

I changed my C# code to check what happened

Process.Start(@"C:\Windows\System32\dnscmd.exe");

我仍然收到无法识别..."错误.但是我可以在"C:\ Windows \ System32"中看到dnscmd.exe.我再次更改了C#代码以检查另一件事:

I still get "not recognized ..." error.but I can see dnscmd.exe in "C:\Windows\System32".I changed my C# code again to check another thing:

Process.Start(@"C:\Windows\System32\cmd.exe");

，然后将打开CMD窗口???有什么主意吗?

and after that CMD windows will be opened???any idea?

推荐答案

在回答第二个问题时，您始终可以检查环境变量 PROCESSOR_ARCHITECTURE 以查看其是否包含数字 64.

In answer to your second question, you can always check the environmental variable PROCESSOR_ARCHITECTURE to see if it contains the number 64.

set servername=%1
set siteaddress=%2

if "%PROCESSOR_ARCHITECTURE%" equ "%PROCESSOR_ARCHITECTURE:64=%" (
  REM 32bit
  "C:\Windows\System32\dnscmd.exe" %servername% /zoneadd %siteaddress% /primary /file  %siteaddress%.dns
) else (
  REM 64bit
  "%windir%\Sysnative\dnscmd.exe" %servername% /zoneadd %siteaddress% /primary /file  %siteaddress%.dns
)

可能更可靠的方法是从注册表中获取它:

Possibly a more reliable method is to get it from the registry:

set servername=%1
set siteaddress=%2

for /f "tokens=3" %%x in ('reg Query HKLM\Hardware\Description\System\CentralProcessor\0 /v Identifier') do (
  set arch=%%x
)
if %!arch:~-2!%==64 (
  set dnsPath=%windir%\Sysnative
) else (
  SET dnsPath=C:\Windows\System32
)
"%dnsPath%\dnscmd.exe" %servername% /zoneadd %siteaddress% /primary /file  %siteaddress%.dns
