Use the CreateDirectory() Method to Create a Folder in C#

We will use the system-defined method CreateDirectory() to create a new folder in a specified directory. If the folder already exists, then it does not take any action. The correct syntax to use this function is as follows.

System.IO.Directory.CreateDirectory(string path);

The built-in method CreateDirectory() has only one parameter. The detail of its parameter is as follows.

This method returns a DirectoryInfo object, which shows the directory at the specified path.

The program below shows how we can use the CreateDirectory() method to create a new folder.

using System;
using System.IO;

class CreateFolder {
  static void Main() {
    string folderPath = @"D:\MyFolder";
    if (!Directory.Exists(folderPath)) {
      Directory.CreateDirectory(folderPath);
      Console.WriteLine(folderPath);
    }
  }
}

We have created a folder named MyFolder in local disk D. We have passed the folder path. The method will create the folder if it does not exist.

Output:

D:\MyFolder
