C# process with an input and output file

Question

When creating a new process you can give some StartInfo with it before you start the process. But how would one give the input of/output to parameter. the output to is achievable through a File.WriteAllLines() with the output of the command.

But now the following must me achieved:

C:\Windows\System32\inetsrv\appcmd.exe add site /in < iisSite.xml

But when we give the

add site /in < iisSite.xml 

with the arguments method of StartInfo appcmd thinks it is a parameter for it's program. See this error

  Failed to process input: The parameter      

  'd:\import\iisSite.xml' must begin with a / or - (HRESULT=80070057).

So we need somehow the same parsing as the command prompt would do it.

What could be possible is something like ReadAllLines and use that as an input, but I thought maybe there is a better solution. Any suggestions?

Thanks in advance!

Answer 1

Stream redirection like that is a feature of the command processor cmd . If you want to do that then you need to invoke it and send your arguments. See EDIT2 and EDIT3 in this post .

Answer 2

using < is not the way to do it. Use >

so for example: appcmd.exe add site /in > iisSiteExport.xml

and have your program spit out all the output as if it was printing to the Console
