Code after Process.Start() call not running, but working when debugging C#

Here is the function that is calling Process.Start().
I am simply opening two folders in WinMerge. This part works correctly and this application pops up. None of the code written after this runs though. However, when I place a breakpoint on p.Dispose() or p.Start() and press continue, everything afterwards works correctly.
private void openWinMerge(string leftFile, string rightFile)
{
string args = "/C /f *.xml " + leftFile + " " + rightFile;
Process p = new Process();
p.StartInfo.FileName = "C:\\Program Files (x86)\\WinMerge\\WinMergeU.exe";
p.StartInfo.Arguments = args;
p.StartInfo.CreateNoWindow = true;
if (p.Start())
{
p.Dispose();
return;
}
}
This is where I call the function calling Process.Start(). None of the code below openWinMerge() runs.
private void btnStart_Click(object sender, EventArgs e)
{
if (txtSerial.Text.Length == 9)
{
PO.Number = txtSerial.Text.ToUpper();
PO.SerialSearch = true;
if (PO.Search())
{
txtPO.Text = PO.Field.ProductionOrderNumber;
search();
createFolders();
copyDefaultFiles();
copyBackupFiles();
openWinMerge("\"" + Path.Combine(path, "INITIAL") + "\"", "\"" + Path.Combine(path, "Default") + "\"");
copyFinalXML();
return;
}
MessageBox.Show("Invalid Serial");
} else if (txtPO.Text.Length == 12)
{
PO.Number = txtPO.Text.ToUpper();
if (PO.Search())
{
txtSerial.Text = PO.Field.SerialNumber;
search();
createFolders();
copyDefaultFiles();
copyBackupFiles();
openWinMerge("\"" + Path.Combine(path, "INITIAL") + "\"", "\"" + Path.Combine(path, "Default") + "\"");
copyFinalXML();
return;
}
MessageBox.Show("Invalid PO or Missing Serial");
} else
{
MessageBox.Show("Please Enter either Serial or PO of Analyzer");
}
}
Update:
I wrote some other code below openWinMerge() and it runs, so my issue is in copyFinalXML()
Here is the code for that
private void copyFinalXML()
{
try
{
string[] files = Directory.GetFiles(Path.Combine(path,"INITIAL"));
Task.Delay(200);
foreach (string file in files)
{
// Will not overwrite if the destination file already exists.
string[] folders = file.Split('\\');
string filename = folders[folders.Length - 1];
if (filename.Equals("config.xml") || filename.Equals("service.xml") || filename.Equals("system.xml"))
{
string d = Path.Combine(Path.Combine(path, "FINAL"), filename);
File.Copy(file, d);
Task.Delay(500);
openNotePad(d);
}
}
}
// Catch exception if the file was already copied.
catch (IOException copyError)
{
MessageBox.Show(copyError.Message);
}
}
private void openNotePad(string filename)
{
//Process.Start("C:\\Program Files(x86)\\Notepad++\\notepad++.exe", "\"" + filename + "\"");
Process.Start(#"notepad++.exe", "\"" + filename + "\"");
return;
}

Add p.WaitForExit(); to your code just before the code you want to execute after it finishes running the process.

C# Starting process with args in specific folder

I am trying to decompile over 30k vulkan shader files using shaderc from google.
All shaders are located in "C:\Users\Admin\Desktop\NMS MOD\SHADER MOD\v2.41\PC"
The tool used to decompile is spirv-cross.exe which I added to Windows Environment variables, which lets me run this simple bat file inside the shaders folder and works fine.
"spirv-cross --version 450 --vulkan-semantics --stage frag ATMOSPHERE_FRAG_CLOUD_769.SPV > ATMOSPHERE_FRAG_CLOUD_769.GLSL"
Since there is way too many to do this manually. I want to make a simple App to do this process and also get the stage type from file name (in this case "frag").
using System;
using System.IO;

Expected behaviour with white space in the command line

I wrote a program that compiles my .cs files using csc.exe:
namespace myCompiler
{
public partial class Form1 : Form
{
string compilerFolder;
string outputFolder;
string projectFile;
string output = #" /out:";
public Form1()
{
InitializeComponent();
}
private void startCompile_Click(object sender, EventArgs e)
{
Compile();
}
public void findCompile_Click(object sender, EventArgs e)
{
DialogResult result1 = folderBrowserDialog1.ShowDialog();
compilerFolder = folderBrowserDialog1.SelectedPath;
MessageBox.Show(compilerFolder);
cscLabel.Text = compilerFolder;
}
private void outputCompile_Click(object sender, EventArgs e)
{
DialogResult result2 = folderBrowserDialog2.ShowDialog();
outputFolder = folderBrowserDialog2.SelectedPath;
outputLabel.Text = (outputFolder);
MessageBox.Show(outputFolder);
}
private void findProject_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
projectFile = openFileDialog1.FileName;
projectLabel.Text = (projectFile);
MessageBox.Show(projectFile);
}
}
public void Compile()
{
try
{
Process compile = new Process();
string outputExe = fileName.Text;
string compiler = compilerFolder + #"\csc.exe";
string arGs = output + outputFolder + #"\" + outputExe + " " + projectFile;
compile.StartInfo.FileName = (compiler);
compile.StartInfo.Arguments = (arGs);
compile.StartInfo.RedirectStandardOutput = true;
compile.StartInfo.UseShellExecute = false;
compile.Start();
string stdOutput = "";
while (!compile.HasExited)
{
stdOutput += compile.StandardOutput.ReadToEnd();
MessageBox.Show(stdOutput);
}
}
catch (Exception errorMsg)
{
MessageBox.Show(errorMsg.Message);
}
}
private void testButton_Click(object sender, EventArgs e)
{
MessageBox.Show(projectFile);
MessageBox.Show(compilerFolder);
}
}
}
The compile instruction runs but produces no results, just a quick flash of a black console screen.
Basically what seems to be happening, is when all the strings are parsed in the commandline as arguments for the process, the .cs project source directory is broken up by each white space ie c:\users\%username%\Documents\Visual Studio 2010\ is broken up as c:\users\%username%\Documents\Visual then Studio then 2010\Projects\Myproject\myproj.cs
and subsequently the compilation fails.

You need double quotes around a filepath with spaces in it.
See my edit to your code below.
public void Compile()
{
try
{
Process compile = new Process();
string outputExe = fileName.Text;
string compiler = compilerFolder + "\csc.exe";
// add double quotes around path with spaces in it.
string arGs = output + "\"" + outputFolder + "\"" + #"\" + outputExe + " " + projectFile;
compile.StartInfo.FileName = compiler;
compile.StartInfo.Arguments = arGs;
compile.StartInfo.RedirectStandardOutput = true;
compile.StartInfo.UseShellExecute = false;
compile.Start();
string stdOutput = "";
while (!compile.HasExited)
{
stdOutput += compile.StandardOutput.ReadToEnd();
MessageBox.Show(stdOutput);
}
}
catch (Exception errorMsg)
{
MessageBox.Show(errorMsg.Message);
}
}
