C# DirectoryInfo Example
In the following example, we are creating a tutoraspire directory by specifying the directory path.
Output:
The directory is created successfully.
In below screenshot, we can see that a directory is created.
The DirectoryInfo class also provides a delete method to delete created directory. In the following program, we are deleting a directory that we created in previous program.
C# DirectoryInfo Example: Deleting Directory
Output:
The directory is deleted successfully.
It throws a System.IO.DirectoryNotFoundException exception if the specified directory not present at the location.
