the Process Class in C#

The Process allows developers to access both local and remote processes and start and stop processes running on the local system.

When a process is launched, a set of values defined by the term ProcessStartInfo are brought into play. The System.Diagnostics namespace is where you’ll find the Process class.

Open a Folder Using Process.Start in C#

Let’s have an example to understand open explorer or any specific folder. In the below example, we’ll open the Videos folder, which is located in the Downloads folder.

Follow the below steps to start explorer with Process.Start.

1. Firstly, we have to import the following libraries.

   using System;
   using System.Diagnostics;
   using System.Collections.Generic;
   using System.Linq;
   using System.Text;
   using System.Threading.Tasks;
   

2. Let’s create a class called Program. Inside the Program class, we’ll make the Main() function.

   class Program {
     static void Main() {}
   }
   

3. Now, we’ll pass the folder path to the Process.Start() function, as shown below.

   Process.Start(@"C:\Users\Shanii\Downloads\Video");
   Console.WriteLine("Folder Opened");
   

Complete Source Code:

using System;
using System.Diagnostics;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

class Program {
  static void Main() {
    Process.Start(@"C:\Users\Shanii\Downloads\Video");
    Console.WriteLine("Folder Opened");
  }
}

Output:

The specified folder will be opened by executing the above example.
