Cannot start .exe application using C # code

Question

I have an exe that I need to call from my C # Program with two arguments (PracticeId, ClaimId)

For example: Suppose I have a test.exe application whose functionality is to make a request in accordance with these two arguments.

In cmd, I usually issued the following command:

test.exe 1 2

And it works great and does its conversion work.

But I want to accomplish the exact same thing using my C # code. I am using the following code example:

 Process compiler = new Process(); compiler.StartInfo.FileName = "test.exe" ; compiler.StartInfo.Arguments = "1 2" ; compiler.StartInfo.UseShellExecute = true; compiler.StartInfo.RedirectStandardOutput = true; compiler.Start(); 

When I try to call test.exe using the above code, it cannot do its job of creating a txt file claim.

Where is the problem with this? Whether the problem is a thread or not, I don't know.

Can someone please tell me what I need to change in the above code?

Answer 1

The code you provided does not work with the following error on startup:

System.InvalidOperationException

The Process object must have the UseShellExecute property set to false to redirect input / output streams.

The following code runs correctly and passes arguments through:

 var compiler = new Process(); compiler.StartInfo.FileName = "test.exe"; compiler.StartInfo.Arguments = "1 2"; compiler.StartInfo.UseShellExecute = true; compiler.StartInfo.RedirectStandardOutput = false; compiler.Start(); 

Answer 2

although I have not tested my code yet, but hope this helps you do what you want to do ...

Process.Start ("xyz.exe", "1 2");

Let me know if this works or not.

Check what is your working directory. Is test.exe in your path? If not, you will need to specify a path. Good practice is to provide a path if you know where it is. You can dynamically build this from the application path, the build path, or customization preferences.

MSDN should help. They look like they have updated the site, and the example for your specific question is very detailed.
