C# StreamWrite to Process not executing on flush

I'm executing a jar file from a c# process. This is how I start the process and redirect the Input & Output. Problem indicated at the bottom!
Process process = new Process();
process.EnableRaisingEvents = false;
if (isLinux)
{
process.StartInfo.WorkingDirectory = Directory.GetCurrentDirectory() + "/Servers/" + server.ServerLocation + "/";
}
else
{
process.StartInfo.WorkingDirectory = Directory.GetCurrentDirectory() + "\\Servers\\" + server.ServerLocation + "\\";
}
process.StartInfo.FileName = "java";
process.StartInfo.Arguments = "-Xms" + server.AllocatedRam + "M -Xmx" + server.AllocatedRam + "M -jar " + '"' + path + '"';
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.CreateNoWindow = true;
LogController.Notice("Server Starting", server.Name);
proc = process;
process.Start();
if (Write.ContainsKey(server.ID))
{
Write.Remove(server.ID);
Write.Add(server.ID, process.StandardInput);
}
else
{
Write.Add(server.ID, process.StandardInput);
}
if (Output.ContainsKey(server.ID))
{
Output.Remove(server.ID);
Output.Add(server.ID, process.StandardOutput);
}
else
{
Output.Add(server.ID, process.StandardOutput);
}
Dictionaries
public static Dictionary<string, StreamWriter> Write = new Dictionary<string, StreamWriter>();
public static Dictionary<string, StreamReader> Output = new Dictionary<string, StreamReader>();
Executing command without closing writer
StreamWriter w = ServerController.Write[ID];
w.Write(Command.command);
w.Flush();
^ Flushing this will not execute the write. If I dispose the writer then I cannot execute more than 1 command. The writer has to always be open for writes and be able to execute the write but flushing does not work.

Executing line commands arguments with 2 variables problem c#

I am trying to open my .exe "application" with 2 arguments. When I write the command line myself without " " it don't want to work. When I write the command line using "C:/Path" "A" "B" it does work.
How do I fix this?
if(element.SaveType == "1")
{
DirectoryInfo srcDir = new DirectoryInfo((string)element.SourcePath);
DirectoryInfo dstDir = new DirectoryInfo((string)element.DestinationPath);
if (element.didEncrypt == true)
{
if (Directory.GetFiles(srcDir.FullName, ((string)element.EncryptExt)).Length == 0)
{
string pat = System.IO.Path.Combine(#"C:\Users\Client Fractal\source\repos\CryptoSoft\CryptoSoft\bin\Debug\netcoreapp3.0\CryptoSoft.exe");
Process p = new Process();
p.StartInfo.FileName = pat;
p.StartInfo.Arguments = srcDir.FullName + dstDir.FullName; // source / target;
Console.WriteLine(p.StartInfo.Arguments);
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.Start();
}
}
}

Command-line arguments are space-character delimited, so you'd need to insert a space character or your arguments will end up getting squashed together.
p.StartInfo.Arguments = srcDir.FullName + " " + dstDir.FullName;
But of course, if either srcDir.FullName or dstDir.FullName contain space characters of their own (and FullName suggests they do), you will need to surround them with double quote characters.
p.StartInfo.Arguments = "\"" srcDir.FullName + "\" \"" + dstDir.FullName + "\"";

Unzip a file in c# using 7z.exe

I'm trying to unzip a file from a winform application.
I'm using this code :
string dezarhiverPath = #AppDomain.CurrentDomain.BaseDirectory + "\\7z.exe";
ProcessStartInfo pro = new ProcessStartInfo();
pro.WindowStyle = ProcessWindowStyle.Hidden;
pro.FileName = dezarhiverPath;
pro.Arguments = #" e c:\TEST.ZIP";
Process x = Process.Start(pro);
x.WaitForExit();
The code doesn't return error but doesn't anything.
I tried this command also from cmd :
K:\>"C:\Test\7z.exe" e "c:\TEST.ZIP"
but in cmd ,I receive this error message :
7-Zip cannot find the code that works with archives.
Can somebody help me to unzip some files from c# ?
Thanks!

Why would you bother trying to use the 7z.exe application externally? That is a very kludgy way of doing it. Instead use one of the many libraries at your disposal.
If this is a new application, and you are targeting .NET 4.5, The new System.IO.Compression namespace has a ZipFile class.
Alternatively, SharpZipLib is a GPL library for file compression in .NET. There are online samples.
Also available is DotNetZip which is Ms-PL licensed.

Hey use this code below , you must have 7zip application in your system .
public void ExtractFile(string source, string destination)
{
string zPath = #"C:\Program Files\7-Zip\7zG.exe";// change the path and give yours
try
{
ProcessStartInfo pro = new ProcessStartInfo();
pro.WindowStyle = ProcessWindowStyle.Hidden;
pro.FileName = zPath;
pro.Arguments = "x \"" + source + "\" -o" + destination;
Process x = Process.Start(pro);
x.WaitForExit();
}
catch (System.Exception Ex) {
//DO logic here
}
}
to create :
public void CreateZip()
{
string sourceName = #"d:\a\example.txt";
string targetName = #"d:\a\123.zip";
ProcessStartInfo p = new ProcessStartInfo();
p.FileName = #"C:\Program Files\7-Zip\7zG.exe";
p.Arguments = "a -tgzip \"" + targetName + "\" \"" + sourceName + "\" -mx=9";
p.WindowStyle = ProcessWindowStyle.Hidden;
Process x = Process.Start(p);
x.WaitForExit();
}

Refer Following Code:
using System.IO.Compression;
string startPath = #"c:\example\start";
string zipPath = #"c:\example\result.zip";
string extractPath = #"c:\example\extract";
ZipFile.CreateFromDirectory(startPath, zipPath);
ZipFile.ExtractToDirectory(zipPath, extractPath);

You can use SevenZipSharp library
using (var input = File.OpenRead(lstFiles[0]))
{
using (var ds = new SevenZipExtractor(input))
{
//ds.ExtractionFinished += DsOnExtractionFinished;
var mem = new MemoryStream();
ds.ExtractFile(0, mem);
using (var sr = new StreamReader(mem))
{
var iCount = 0;
String line;
mem.Position = 0;
while ((line = sr.ReadLine()) != null && iCount < 100)
{
iCount++;
LstOutput.Items.Add(line);
}
}
}
}

Try this
string fileZip = #"c:\example\result.zip";
string fileZipPathExtactx= #"c:\example\";
ProcessStartInfo p = new ProcessStartInfo();
p.WindowStyle = ProcessWindowStyle.Hidden;
p.FileName = dezarhiverPath ;
p.Arguments = "x \"" + fileZip + "\" -o" + fileZipPathExtact;
Process x = Process.Start(p);
x.WaitForExit();

This maybe can help you.
//You must create an empty folder to remove.
string tempDirectoryPath = #"C:\Users\HOPE\Desktop\Test Folder\zipfolder";
string zipFilePath = #"C:\Users\HOPE\Desktop\7za920.zip";
Directory.CreateDirectory(tempDirectoryPath);
ZipFile.ExtractToDirectory(zipFilePath, tempDirectoryPath);

Spaces in command line argument not working

I have requirement to execute the command line arguments. If file path contains the Spaces it doesn’t work properly. It returns the error file not found. The program is given below.
public void Method()
{
string docFile = #"C:\Test Document1.doc";
string docxFile = #"C:\Test Document1.docx";
string file = #"C:\doc2x_r649 (1)\doc2x_r649\doc2x.exe";
ExecuteCommand(file, string.Format(docFile + " -o " + docxFile));
}
public static string ExecuteCommand(string file, string command)
{
String result;
try
{
//Create a new ProcessStartInfo
System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo();
//Settings
procStartInfo.UseShellExecute = false;
procStartInfo.CreateNoWindow = false;
procStartInfo.RedirectStandardOutput = true;
procStartInfo.FileName = file;
procStartInfo.Arguments = command;
//Create new Process
System.Diagnostics.Process proc = new System.Diagnostics.Process();
//Set ProcessStartInfo
proc.StartInfo = procStartInfo;
//Start Process
proc.Start();
//Wait to exit
proc.WaitForExit();
//Get Result
result = proc.StandardOutput.ReadToEnd();
//Return
return result;
}
catch
{
}
return null;
}
If file path doesn't contains spaces it works properly.

Have you tried adding quotes to your paths?
ExecuteCommand(file, string.Format("\"" + docFile + "\" -o \"" + docxFile + "\""));

Try this
ExecuteCommand(file, string.Format("\"{0}\" -o \"{1}\"",docFile , docxFile));

How to uninstall Software using c# by calling Software UninstallString Listed in Registry file of that Software But the Process Is Not Working

I am developing a software that will list all the software install
in Computer
now i want to Uninstall it using my Program In C# by
calling the Uninstall Key of that software in
Registry Key
My Program Is
Like That But the Process Is Not Working
var UninstallDir = "MsiExec.exe /I{F98C2FAC-6DFB-43AB-8B99-8F6907589021}";
string _path = "";
string _args = "";
Process _Process = new Process();
if (UninstallDir != null && UninstallDir != "")
{
if (UninstallDir.StartsWith("rundll32.exe"))
{
_args = ConstructPath(UninstallDir);
_Process.StartInfo.FileName = Environment.SystemDirectory.ToString() + "\\explorer.exe";
_Process.StartInfo.Arguments = Environment.SystemDirectory.ToString() + "\\" + UninstallDir;
_Process.Start();
}
else if (UninstallDir.StartsWith("MsiExec.exe"))
{
_args = ConstructPath(UninstallDir);
_Process.StartInfo.FileName = Environment.SystemDirectory.ToString() + "\\cmd.exe";
_Process.StartInfo.Arguments = Environment.SystemDirectory.ToString() + "\\" + UninstallDir;
_Process.Start();
}
else
{
//string Path = ConstructPath(UninstallDir);
_path = ConstructPath(UninstallDir);
if (_path.Length > 0)
{
_Process.StartInfo.FileName = _path;
_Process.StartInfo.UseShellExecute = false;
_Process.Start();
}
}

Try this approach:
Process p = new Process();
p.StartInfo.FileName = "msiexec.exe";
p.StartInfo.Arguments = "/x {F98C2FAC-6DFB-43AB-8B99-8F6907589021}/qn";
p.Start();
Refer to this link: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/msiexec.mspx?mfr=true
HTH.

The problem with your misexec.exe code is that running cmd.exe someprogram.exe doesn't start the program because cmd.exe doesn't execute arguments passed to it. But, you can tell it to by using the /C switch as seen here. In your case this should work:
_Process.StartInfo.FileName = Environment.SystemDirectory.ToString() + "\\cmd.exe";
_Process.StartInfo.Arguments = "/C " + Environment.SystemDirectory.ToString() + "\\" + UninstallDir;
Where all I did was add /C (with a space after) to the beginning of the arguments. I don't know how to get your rundll32.exe code to work, however.

Your solution looks good, but keep a space before \qn:
p.StartInfo.Arguments = "/x {F98C2FAC-6DFB-43AB-8B99-8F6907589021} /qn";
Otherwise it wont work in silent mode.
