Execute Batch File From C# Console

Question

Let's say from my C# console application I want to run a batch file that will take two arguments. The two string variables at the top of the  C# application will be the string arguments to pass to the batch file. How would I go about doing it?

Here is my code so far my C# console program:

    

string argumentOne = "Hello World";
string argumentTwo = "How are You";
            
          
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
//startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "Greetings.bat";
//How do I insert two arguments?
//startInfo.Arguments = "/C " + message;
process.StartInfo = startInfo;
process.Start();
             

My Batch File

CLS
@ECHO OFF
ECHO %1 %2

Answer 1

you can use "arguments" - like this

string argumentOne = "\"Hello World\"";
string argumentTwo = "\"How are You\"";

startInfo.FileName = "Greetings.bat";

startInfo.Arguments = string.Format("{0} {1}",argumentOne,argumentTwo);

// startInfo.Arguments = argumentOne + " " + argumentTwo;
// startInfo.Arguments += argumentOne;
// startInfo.Arguments += " ";
// startInfo.Arguments += argumentTwo;
process.StartInfo = startInfo;
process.Start();

You need to put double quotes around arguments that contain whitespaces.
Also - because of the /C switch - seems you want to launch
cmd.exe and pass the the batch file also as an argument:

string argumentOne = "Hello World";
string argumentTwo = "How are You";
string batchFile   = "Greetings.bat";
          
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.FileName = System.Environment.GetEnvironmentVariable("COMSPEC");
startInfo.Arguments = string.Format("/C {0} \"{1}\" \"{2}\"", batchFile, argumentOne, argumentTwo);
process.StartInfo = startInfo;
process.Start();
             

Note the quotes will NOT be removed in the batch file.
If you need to remove them, you can do it like this:

@ECHO OFF
CLS
FOR %%A in (%1) do set ARG1=%%~A
FOR %%A in (%2) do set ARG2=%%~A
ECHO %ARG1% %ARG2%
