Launching a batch file - c#

I have the following code:
String Antcbatchpath = #"C:\GUI\antc.bat";
System.Diagnostics.Process runantc = new System.Diagnostics.Process();
runantc.StartInfo.FileName = Antcbatchpath;
runantc.StartInfo.UseShellExecute = false;
runantc.StartInfo.RedirectStandardOutput = true;
runantc.StartInfo.RedirectStandardError = true;
runantc.Start();
Will this load the batch file from C:\GUI\antc.bat?
Or runantc.StartInfo.FileName is only for a root directory? Root directory is where the application is located
EDIT 1:
hi instead of #"C:\GUI\antc.bat" i have a path:
String Antcbatchpath =#"C:\GUI Lab Tools\Build Machine\antc.bat";
which essentially contains white spaces. will it affect the runantc.StartInfo.Filename = Antcbatchpath; ?

UseShellExecute = true should do it.
Alternatively, if you need redirection, use:
runantc.StartInfo.FileName = "CMD.EXE";
runantc.StartInfo.Arguments = "/C " + Antcbatchpath;

You can try to set WorkingDirectory to prevent any ambiguity, but in my experience, it is not necessary.
The problem you're having is because antc.bat is not an executable. It requires UseShellExecute to be true, but that would prevent you from redirecting the output. I guess you will have to choose either one.

How to open and use Git Bash through c# code

I'm trying to include opening Git Bash, pushing and pulling in my c# code. Whilst opening Git Bash with Process.Start() is not the problem, I cannot manage to write commands into Git Bash.
I've tried including commands in ProcessStartInfo.Arguments, as well as redirecting the standard Output. Both has not worked at all. Down below you can see the different code snippets I tried.
private void Output()
{
//Try 1
processStartInfo psi = new ProcessStartInfo();
psi.FileName = "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Git\Git Bash.lnk";
psi.UseShellExecute = false;
psi.RedirectStandardOutput = true;
psi.Argument = "git add *";
Process p = Process.Start(psi);
string strOutput = p.StandardOutput.ReadToEnd();
Console.WriteLine(strOutput);
//Try 2
ProcessStartInfo psi = new ProcessStartInfo(#"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Git\Git Bash.lnk");
Process.Start(psi);
psi.Arguments = "git add *";
Process.Start(psi);
//Try 3
var escapedArgs = cmd.Replace("\"", "\\\"");
var process = new Process()
{
StartInfo = new ProcessStartInfo
{
FileName = #"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Git\Git Bash.lnk",
Arguments = "cd C:\\Users\\strit\\autocommittest2\\autocommittest2\n",
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true,
}
};
process.Start();
string result = process.StandardOutput.ReadToEnd();
process.WaitForExit();
}
Git Bash opens but nothing is written in the command line.
I know it is old question, still adding answer as few days ago I was also facing same issue.
I think what you are missing is -c parameter. I used below code and it solved this issue. -c tells git-bash to execute whatever follows, it is similar to -cmd parameter in command line.
In below mentioned function -
fileName = path of git-bash.exe.
command = git command which you want to execute.
workingDir = Local path of git repository.
public static void ExecuteGitBashCommand(string fileName, string command, string workingDir)
{
ProcessStartInfo processStartInfo = new ProcessStartInfo(fileName, "-c \" " + command + " \"")
{
WorkingDirectory = workingDir,
RedirectStandardOutput = true,
RedirectStandardError = true,
RedirectStandardInput = true,
UseShellExecute = false,
CreateNoWindow = true
};
var process = Process.Start(processStartInfo);
process.WaitForExit();
string output = process.StandardOutput.ReadToEnd();
string error = process.StandardError.ReadToEnd();
var exitCode = process.ExitCode;
process.Close();
}
I hope it solves the issue.
I think you are on the right way. I would try to use the git in the path, but it should be possible to also use the git-bash.exe directly, at my machine it is located here: C:\Program Files\Git\git-bash.exe.
Process gitProcess = new Process();
gitInfo.Arguments = YOUR_GIT_COMMAND; // such as "fetch origin"
gitInfo.WorkingDirectory = YOUR_GIT_REPOSITORY_PATH;
gitInfo.UseShellExecute = false;
gitProcess.StartInfo = gitInfo;
gitProcess.Start();
string stderr_str = gitProcess.StandardError.ReadToEnd(); // pick up STDERR
string stdout_str = gitProcess.StandardOutput.ReadToEnd(); // pick up STDOUT
gitProcess.WaitForExit();
gitProcess.Close();
Like #S.Spieker already told you in it's good answer, no need to use git bash (it makes it harder to achieve and less performant), just call directly the git executable.
You could have a look to the GitExtensions code that is doing that: https://github.com/gitextensions/gitextensions/blob/027eabec3be497f8d780cc68ece268c64a43a7d5/GitExtensionsVSIX/Git/GitCommands.cs#L112
You could also achieve what you want using libgit2sharp (https://github.com/libgit2/libgit2sharp). That could be easier if you want to interpret the results of the command run.

Unable to find particular file

When in my program I try to launch particular exe-file "nvidia-smi.exe" (NVIDIA System Management Interface program), I receive the error "System.ComponentModel.Win32Exception. The system cannot find the file specified"
string directoryPath = "C:\\";
string fileName = "nvidia-smi.exe";
Console.WriteLine(System.IO.File.Exists(directoryPath + fileName)); //true
proc.StartInfo.WorkingDirectory = directoryPath;
proc.StartInfo.FileName = fileName;
proc.Start(); //Error. The system cannot find the file specified
But at the same time I can :
1) Launch the other files from the same directory (exe, bat etc)
2) Successfully to execute the file I needed "nvidia-smi.exe" if relocate it to my project's directory and do not use the property "proc.StartInfo.WorkingDirectory".
-----------------The answer is (Thanks for help!)------------------
you need this :
proc.StartInfo.UseShellExecute = true;
proc.StartInfo.WorkingDirectory = "C:\\";
proc.StartInfo.FileName = "nvidia-smi.exe";
Or this :
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.FileName = "C:\\nvidia-smi.exe";
If you set proc.StartInfo.UseShellExecute to true, the behavior of WorkingDirectory will be as you expect it to be. Otherwise, you will have to either specify the absolute path for the FileName, or make sure your executable is in your environment path.
Relevant documentation:
UseShellExecute
WorkingDirectory

Running multiple commands from C# application

I want to run several commands via C# application like
Previously I had a batch file and I ran it using C# but now few of the commands can take inputs. But how to do that ?
I tried
Process cmdprocess = new Process();
ProcessStartInfo startinfo = new ProcessStartInfo();
Environment.SetEnvironmentVariable("filename", FileName);
startinfo.FileName = #"C:\Users\cnandy\Desktop\St\2nd Sep\New_CN\New folder\Encrypt web.config_RSAWebFarm\Decrypt Connection String.bat";
startinfo.WindowStyle = ProcessWindowStyle.Hidden;
startinfo.CreateNoWindow = true;
startinfo.RedirectStandardInput = true;
startinfo.RedirectStandardOutput = true;
startinfo.UseShellExecute = false;
cmdprocess.StartInfo = startinfo;
cmdprocess.Start();
And in the batch file
cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319
aspnet_regiis -pi "CustomKeys2" "C:\Users\cnandy\Desktop\Encryption_keys\CustomEncryptionKeys.xml"
aspnet_regiis -pa "CustomKeys2" "NT AUTHORITY\NETWORK SERVICE"
aspnet_regiis -pdf "connectionStrings" %filename%
But effectively they did not run get executed at all. How to achieve the same where for the last command I can accept an input instead of hard coding
"C:\Users\cnandy\Desktop\Test\Websites\AccountDeduplicationWeb"
?
Try this:
Process p = new Process()
{
StartInfo = new ProcessStartInfo("cmd.exe")
{
RedirectStandardInput = true,
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true
}
};
p.Start();
using (StreamWriter sw = p.StandardInput)
{
sw.WriteLine("First command here");
sw.WriteLine("Second command here");
}
p.StandardInput.WriteLine("exit");
Alternatively, try this more direct way (which also implements the last thing you requested):
string strEntry = ""; // Let the user assign to this string, for example like "C:\Users\cnandy\Desktop\Test\Websites\AccountDeduplicationWeb"
Process p = new Process()
{
StartInfo = new ProcessStartInfo("cmd.exe")
{
RedirectStandardInput = true,
RedirectStandardOutput = true,
UseShellExecute = false,
CreateNoWindow = true
}
};
p.Start();
p.StandardInput.WriteLine("cd C:\\Windows\\Microsoft.NET\\Framework64\\v4.0.30319");
p.StandardInput.WriteLine("aspnet_regiis -pi \"CustomKeys2\" \"C:\\Users\\cnandy\\Desktop\\Encryption_keys\\CustomEncryptionKeys.xml\"");
p.StandardInput.WriteLine("aspnet_regiis -pa \"CustomKeys2\" \"NT AUTHORITY\\NETWORK SERVICE\"");
p.StandardInput.WriteLine("aspnet_regiis -pdf \"connectionStrings\" " + strEntry);
p.StandardInput.WriteLine("exit"); //or even p.Close();
If using the second way, it is recommended to let the user enter the path in a textbox, then grab the string from the textbox's Text property, where all the necessary extra back-slashes will be automatically appended.
It should be mentioned that no cmd will show up running your batch file, or the commands.
You can still make a batch file as you used to. Only change it needs is accepting variables.
Something like
CallYourBatch.bat "MyFileName"
Then in you batch file, you can accept a parameter
SET fileName=%~1
aspnet_regiis -pdf "connectionStrings" %fileName%
Similarly the same functionality can be used while forming your command text, if you must do it as part of C# code.
Also might i suggest using a CALL command to call your batch files? More information on the same is at http://ss64.com/nt/call.html
Start the batch file using Process object. You can use Environment variables to pass the values between processes. in this case, from C# to bat file you can pass values using environment variable.
c#
Environment.SetEnvironmentVariable("searchString","*.txt")
in bat file you can access the value as like below
dir %searchString%
To start the bat file from c#
System.Diagnostics.Process.Start("path\commands.bat");
Sample code to start notepad from C# with Batch file and Variables
System.Environment.SetEnvironmentVariable("fileName", "test.txt");
System.Diagnostics.Process.Start(System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().Location) + "/commands.bat");
Console.ReadLine();
Bat file
#echo "staring note pad"
notepad %fileName%

Executing batch file located on remote machine

I'm trying to execute a batch file that is located on a remote machine with the following line of code:
System.Diagnostics.Process.Start(\\10.0.24.103\somePath\batchFile.bat);
And it blocks on this line of code. When I try to run it manually (by writing that address in Windows Explorer), it works, but I have to accept a security warning message first. I'm assuming this is why it's blocking when it's done through code...is there any way to force it to execute through code?
I solved my problem by adding more detail to the ProcessStartInfo object:
var process = new Process();
var startInfo = new ProcessStartInfo
{
CreateNoWindow = true,
FileName = "cmd.exe",
Arguments = "/c \"\"" + batchFile + "\"\"",
WorkingDirectory = AppDomain.CurrentDomain.BaseDirectory,
UseShellExecute = false,
RedirectStandardError = true,
RedirectStandardOutput = true
};
process.StartInfo = startInfo;
process.Start();
process.WaitForExit(30000);
I needed to specify to use cmd.exe, as well as surrounding the batchFile path in double quotes in case there are spaces in the path.
Try prefacing it with cmd /c(that's a space after /c).
Is this IP address a Windows machine on your domain etc.

How to redirect STDIN .NET Process before Starting the process

Im trying to make C# application that uses hunpos tagger.
Runing hunpos-tag.exe requires three input arguments: model, inputFile, outputFile
In cmd it would look something like this:
hunpos-tag.exe model <inputFile >outputFile
If I just run it with model it writes something and waits for end command. When i tried using standard redirect I either get an exception (i solved this the code was off by a braceket i just get the or scenario now) or I get the results of running the tagger with just model argument. Here's the code:
string inputFilePath = path + "\\CopyFolder\\rr";
string pathToExe = path + "\\CopyFolder\\hunpos-tag.exe";
ProcessStartInfo startInfo = new ProcessStartInfo
{
FileName = pathToExe,
UseShellExecute = false,
RedirectStandardInput = true,
WorkingDirectory = Directory.GetDirectoryRoot(pathToExe),
Arguments = path + "\\CopyFolder\\model.hunpos.mte5.defnpout",
};
try
{
Process _proc = new Process();
_proc.StartInfo.FileName = pathToExe;
_proc.StartInfo.UseShellExecute = false;
_proc.StartInfo.RedirectStandardInput = true;
_proc.StartInfo.Arguments = path + "\\CopyFolder\\model.hunpos.mte5.defnpout";
//Magic goes here
_proc.Start();
_proc.WaitForExit();
}
catch (Exception e)
{
Console.WriteLine(e);
}
Any ideas how can I redirect input before starting my process?
It is not only required to set RedirectStandardInput to true but also you need to use the input stream to write the text you want:
_proc.StandardInput.WriteLine("The text you want to write");
There's no need for that ProcessStartInfo if you're setting the info later on. Just get rid of that. And it seems you are already doing what you want. Just creating the process object doesn't start the process, Process.Start does. Just make a new StreamWriter and pass it Process.StandardInput (I think that's right, it may be something else)
