Hi
I have implemented a small application which will invoke the Git-bash.exe and execute a command to get the list of files associated with the commit id. I am sure the whole code is correct except the way I pass the arguments to the Process. Can some one please let me know how to pass the Git bash argument to C# Process. I googled alot and dint find a right way to provide this argument.




I know the issue is in below line
gitInfo.Arguments = "-c \"" + "git diff-tree -r 61140bb40f879dd21e8624fe8e2125df846572e8" + "\"";


Can some one let me know how to pass the arguments in right way.

What I have tried:

ProcessStartInfo gitInfo = new ProcessStartInfo();
gitInfo.CreateNoWindow = false;
gitInfo.UseShellExecute = false;
gitInfo.RedirectStandardError = true;
gitInfo.RedirectStandardOutput = true;
gitInfo.FileName = @"C:\Program Files\Git\git-bash.exe";
Process gitProcess = new Process();

gitInfo.WorkingDirectory = @"D:\CodeBranch";
gitInfo.Arguments = "-c \"" + "git diff-tree -r 61140bb40f879dd21e8624fe8e2125df846572e8" + "\"";

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();

That looks correct. What is the problem?

What it is doing that you didn't expect, or not doing that you did?
Are there any error messages?
What have you tried to find out what exactly is happening?

The git-bash window pop ups and disappear immediately. The same command git diff-tree -r 61140bb40f879dd21e8624fe8e2125df846572e8 if i enter manually in git-bash console then i get the list of files properly but when is send it as an arugment in c# process its failing to execute that command. If i comment that arguments part and execute my code then git-bash console is poping up and staying for longer time and hence i feel the way i pass the arguments to the process is wrong.

So what does the debugger say is in the strerr and strout streams?
What does it show - exactly what - is in the arguments property string? (I assume it's not a fixed ID value from the way you have the single argument string spaced out).

strerr_str is empty, since the git-bash console does not have any data in it and the window no longer exists during we read it. The ID is the commit id i have provided which is a valid one in my project.

When i check the value of arguments in visual studio during debugging the value of the arguments is as follows:
-c "git diff-tree -r 61140bb40f879dd21e8624fe8e2125df846572e8"

I could able to solve this issue in different way. Since i am not aware of how to give this command line argument in c# Process, i written a batch file with all those GIT commands and called that batch file from c# code and it worked like a charm..
