C# (CSharp) Process - .NET Framework



Starts a process resource and associates it with a Process component.
Namespace: System.Diagnostics
Assembly: System (in System.dll)

The System.Diagnostics namespace contains functions that allow you to manage processes, threads, eventlogs and performance information.

The System.Diagnostics.Process object gives you access to functionality enabling you to manage system processes. We will use this object to get a list of running processes.

Add this line to your using list:

using System.Diagnostics;

Process. A process starts. It does something important. And then it terminates. With processes, we run separate programs at the level of the operating system.
Start, a static method, calls external applications. It allows users to view documents and web pages. It also executes EXE programs and command-line utilities.
A Project - Arguments:
The Process.Start method has overloaded forms. So you can call it with more than argument.

C# program that open notepad
using System.Diagnostics;

class Program
{
        static void Main()
       {
               // Use Process.Start here.
               Process.Start("Notepad.exe");
       }
}


For more information about this example, here.

ProcessStartInfo:
In this example we use ProcessStartInfo. In it, we can store a process' properties: details of its execution.
C# program that open notepad with argument
using System.Diagnostics;

class Program
{
      static void Main()
     {
           ProcessStartInfo startInfo = new ProcessStartInfo();
           startInfo.FileName = "notepad.exe";
           startInfo.Arguments = "/A C:\filetext.txt";
           Process.Start(startInfo);
      }
}


Properties. To refresh our memory, here is a partial listing of Process properties. We will use most of these when starting programs from a program.
ProcessStartInfo:
Stores information about the process—specifically how the process is started and its configuration.
FileName:
The program or filename you want to run. It can be a program such as "NOTEPAD.EXE". Sometimes we can just specify a file name.
Arguments: Stores the arguments, such as -flags or filename. This is a string property.
CreateNoWindow: Allows you to silently run a command line program. It does not flash a console window.
WindowStyle: Use this to set windows as hidden. ProcessWindowStyle.Hidden is often useful.
UserName, WorkingDirectory, Domain: These control OS-specific parameters—for more complex situations.
