How to Start Processes in C#: Process.Start vs. Process Instance?

Mastering Process Initiation in C#

Launching external applications, opening files, or navigating to web addresses are common programming tasks. C# offers two main methods for process initiation:

• Simplified Process Launch with Process.Start():

For straightforward process starts without extensive customization, the static Start() method of the System.Diagnostics.Process class is ideal.

<code class="language-csharp">using System.Diagnostics;
...
Process.Start("myprogram.exe");</code>

• Advanced Process Control with Process Instance:

For finer-grained control, create a Process class instance. This allows setting the executable path, command-line arguments, window style, and even waiting for process completion.

<code class="language-csharp">using System.Diagnostics;
...
Process process = new Process();
process.StartInfo.FileName = "myprogram.exe";
process.StartInfo.Arguments = "-arg1 -arg2";
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; // Example: Run hidden
process.Start();
process.WaitForExit(); // Wait for process termination</code>

This approach offers flexibility to manage the process lifecycle and execution environment precisely.
