How to create a directory in C#
Before we can create a directory, you must first import the System.IO namespace in C#. The namespace is a library that allows you to access static methods for creating, copying, moving, and deleting directories.
Creating the directory
You can use the Directory.CreateDirectory method to create a directory in the desired path. Take a look at the example below.
string dir = @"C:\test";// If directory does not exist, create itif (!Directory.Exists(dir)){Directory.CreateDirectory(dir);}
In the code above, use Directory.Exists to check whether the directory path exists. If it does not, you can use Directory.CreateDirectory to create the directory.
You can also create sub-directories, as seen below.
string dir = @"C:\test\Aaron";if (!Directory.Exists(dir)){Directory.CreateDirectory(dir);}
To create a sub-directory, you simply have to specify its path.
