Example: C# program for DirectoryInfo Class
The program is used to create a directory in C#.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | using System; using System.IO; namespace FileExample { class Program { static void Main(string[] args) { string fLoc = "Sample"; DirectoryInfo dir = new DirectoryInfo(fLoc); // checking for its existence if (dir.Exists) { Console.WriteLine("The Directory already exists."); } else { // creating directory dir.Create(); Console.WriteLine("Directory Created Successfully!"); } } } } |
Output:
Directory Created Successfully!
A directory named “Sample” will be created on a path that you will specify in a program. The program also checks if the directory specified already exists in that path or not.
Example: C# program for DirectoryInfo Class tp delete a directory
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | using System; using System.IO; namespace FileExample { class Program { static void Main(string[] args) { string fLoc = "sample.text"; DirectoryInfo dir = new DirectoryInfo(fLoc); try { dir.Delete(); Console.WriteLine("Directory Deleted Successfully!"); } catch (Exception ex) { Console.WriteLine("Something is wrong: " + ex.ToString()); } } } } |
Output:
Directory Deleted Successfully!
