C# Program to Create a Directory

A directory is a file system that stores file. Now our task is to create a directory in C#. We can create a directory by using the CreateDirectory() method of the Directory class. This method is used to create directories and subdirectories in a specified path. If the specified directory exists or the given path is invalid then this method will not create a directory. To use CreateDirectory() method we have to import the system.IO namespace in the program.

Syntax:

public static System.IO.DirectoryInfo CreateDirectory (string path);

Parameter: path is the directory path.

Return: This will return the object of the specified created directory.

Exception: It will throw the following exception:

• IOException: This exception occurs when the directory specified by path is a file.
• UnauthorizedAccessException: This exception occurs when the caller does not have the required permission.
• ArgumentException: This exception occurs when the path is prefixed with, or contains, only a colon character (:).
• ArgumentNullException: This exception occurs when the path is null.
• PathTooLongException: This exception occurs when the specified path, file name, or both exceed the system-defined maximum length.
• DirectoryNotFoundException: This exception occurs when the specified path is invalid 
• NotSupportedException: This exception occurs when the path contains a colon character(:) that is not part of a drive label ("D:\").

Example:

Output:

Created
