Create a Directory Using C#

To create, move and delete directories in C#, the System.IO.Directory class has methods.

Firstly, import the System.IO namespace.

Now, use the Director.CreateDirectory() method to create a directory in the specified path −

string myDir = @"D:\NEW";
if (!Directory.Exists(myDir)) {
   Directory.CreateDirectory(myDir);
}

In the same way, you can create a sub-directory −

string mysubdir = @"C:\NEW\my\";
Directory.CreateDirectory(mysubdir);
