I am writing a small utility to execute svn commands using c# program
Here is the key line in my program
System.Diagnostics.Process.Start("CMD.exe", #"svn checkout C:\TestBuildDevelopment\Code");
As I assume, the above code should be able to do svn check out and download all the code to the local path mentioned above. But what's happening is that, the command prompt opens up with the default path of the c# project and does nothing.
If I run this svn command in command line it works fine. But when I run using C# it just pops up the command prompt without executing the svn checkout operation. Any idea on what is going wrong?
You don t have to run CMD.exe. CMD.exe ist just a program that calls other assemblies.
You can call svn.exe directly with your argument checkout ... (but isnt there a url missing?)
Process.Start("svn.exe", #"checkout C:\TestBuildDevelopment\Code");
you may also try this:
Process proc = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.RedirectStandardOutput = true;
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "svn.exe";
startInfo.CreateNoWindow = true;
startInfo.Arguments = "checkout ...";
proc.StartInfo = startInfo;
if(proc.Start()) {
proc.WaitForExit();
}
You need to add the parameter /c. Try:
Process.Start("CMD.exe", #"/c svn checkout C:\TestBuildDevelopment\Code");
The parameter /c means that the cmd should execute the command and exit.
As Jon notes, svnsharp would be a good choice here; but IMO the problem is shelling cmd.exe, rather than the exe you actually want to run:
Process.Start(#"path\to\svn.exe", #"checkout ""C:\TestBuildDevelopment\Code""");
although a ProcessStartInfo would make it easier to set the working path etc.

I'm trying to create a function that backs up one of my important tables using pg_dump --table. The function runs successfully on my localhost and does the dump. but when it is run by my program through IIS on the server, it doesnt seem to do anything.
my project uses .NET Framework 4.7.2 , Here is my program's code:
try{
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.FileName = "cmd.exe";
startInfo.WorkingDirectory = "C:\\Website\\Logs\\";
string fileName = startInfo.WorkingDirectory+RandomString();
startInfo.Arguments =
$"/c set PGPASSWORD={userPassword}&pg_dump --file {fileName} --host {Ip} --port 5432 --username {userName} --no-password --verbose --format=d --table public.clients {DB_Name}";
ServerLogs.SaveLog(startInfo.Arguments); //i am saving the logs
startInfo.Verb = "runas"; //run as administrator
startInfo.CreateNoWindow = true;
startInfo.UseShellExecute = false;
process.StartInfo = startInfo;
process.Start();
process.WaitForExit();
process.Close();
return "Success";
}catch (Exception x)
{
return x.Message;
}
As u can see, i am logging the arguments field on the server. here is the CMD that was generated and executed :
/c set PGPASSWORD=MyPassword&pg_dump --file C:\Website\Logs\abcd\FileName123123 --host mycluster.eu-north-1.rds.amazonaws.com --port 5432 --username test--no-password --verbose --format=d --table public.clients CRM
this CMD that was created is good, when i copy it to the EC2 server's terminal it runs and dumps the table successfully into my specified path. But when it is run by my program through IIS, it only saves the log, but the proccess itself is not dumping the table. not creating any file. pg_dump is recognized and configured well in my env variables.
1.I was thinking the code is ok because it runs well locally
2.I was thinking the CMD is ok because it runs well on the server's terminal.
3.I tried changing the startInfo.arguments to be "type nul > somefile.txt" to see if IIS has permissions to create files on this folder, and it ran successfully.. so i was thinking this isnt a permission issue.
But I could be wrong. Because it is not working.
I tried several methods and solutions online and I am kinda clueless. I would very much appriciate any help or suggestions. Thank you very much!
I'm trying to run a python script from C# as follows:
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = $"/C \"python {Constants.PythonScriptPath} --input-folder {directory} --output-folder {directory}\"";
process.StartInfo = startInfo;
process.Start();
process.WaitForExit();
The script is processing the files from the input folder into the output folder but the processed files count is less than the count when running the same command from the windows command line.
Is there anything that can terminate the execution when calling the cmd.exe from C#?
If anyone faces similar issue :
This issue happened because the application was running in debug mode with visual studio. When publishing the app it's working fine.
Looks like the visual studio is terminating the execution after a specific Time / Memory.
I am running a .NET application on wine in linux. I am trying to run a command that runs a shell script present in the linux. This is my code inside the .NET application, calling the command:
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd";
startInfo.Arguments = "/C /bin/gnome-terminal -- sh -e /bin/MyScripts/script.sh";
process.StartInfo = startInfo;
process.Start();
The gives me error saying that
Can't recognize /bin/gnome-terminal -- sh -e /bin/MyScripts/script.sh as as an internal or external command, operable program or batch file.
However, if I try to run that command directly on wine, that command works fine and executes the script. I have tried running it directly like this:
wine cmd /c /bin/gnome-terminal -- sh -e /bin/MyScripts/script.sh
The application is run on wine using the following command:
wine Application.exe
So I assume if that application runs the command, it will be called the same way it is called directly, so why I am seeing such inconsistent behaviour? What am I doing wrong and what change should I make for the command to work through the application?
Try
startInfo.FileName = "cmd.exe";
I have a program which wraps around some Windows SDK executables and opens them in a separate CMD window.
Process process = new Process();
process.StartInfo.FileName = "cmd.exe";
process.StartInfo.Arguments = "/C signtool.exe [args] & pause";
process.StartInfo.Verb = "runas";
process.Start();
Right now, I have the Windows SDK folder added to my system's Path environment variable. Is there a way to programmatically add the Windows SDK folder to the Path environment variable of the user OR run the process with the SDK folder added to the Path variable of that particular CMD window?
This is the folder I need added to each CMD window's Path variable:
C:\Program Files (x86)\Windows Kits\10\bin\10.0.16299.0\x86
This sub-process must run as administrator. It does not need to receive the output of the child process.
Use a ProcessStartInfo and its Environment property instance to set this up.
var startInfo = new ProcessStartInfo();
var defaultPath = startInfo.Environment["PATH"];
var newPath = "C:\\Program Files (x86)\\Windows Kits\\10\\bin\\10.0.16299.0\\x86" + ";" + defaultPath;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/c set > D:\\env.txt";
startInfo.Verb = "runas";
startInfo.Environment["PATH"] = newPath;
startInfo.UseShellExecute = false; // required to use Environment variables
Process.Start(startInfo);
There are a number of hurdles to overcome here.
As you've discovered, the Environment and EnvironmentVariables properties of ProcessStartInfo cannot be used when UseShellExecute is true (an exception is thrown). But Verb only works when UseShellExecute is false (the Verb is silently ignored). This comes down to the differences between CreateProcess (the core Win32 function) and ShellExecute/ShellExecuteEx (the shell function).
As another commenter suggested, you might try setting the environment in the parent process and then starting the child process. However, elevated processes don't inherit the environment from a non-elevated parent process.
I would be willing to bet that there is a way to do what you want using a correct series of Win32 calls to get an elevated token and then calling something like CreateProcessAsUser. I am also willing to bet it'll be a little error-prone and ugly in C# because of the necessary struct marshaling. So instead of trying to figure that out for you, I'll offer another suggestion:
Just programmatically write a batch script that sets the environment and invokes signtool.exe. You can then invoke that batch script using the runas verb as you're currently doing.
how I can open CMD using my IIS Application
var startInfo = new ProcessStartInfo();
startInfo.WorkingDirectory ="c:\\pdftohtml\\";
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "MyText";
Process proc = Process.Start(startInfo);
I believe this code is true but dose not work with IIS for some reason
Thanks in Advance
Opening a command prompt from an IIS application is not a good idea.
If you need to run a tool, maybe it's better to find the API used by the tool and reference it from a service called by the IIS app.
