find the root directory of a directory in csharp

You can find the root directory of a directory in C# using the Path.GetPathRoot() method. This method returns the root directory of a path, which is the first directory of a path that is followed by a directory separator character. Here's an example of how to use it:

main.cs
using System.IO;

string path = "C:/Users/username/Documents/folder/file.txt";
string root = Path.GetPathRoot(path);

Console.WriteLine("Root directory: " + root);  // Output: "Root directory: C:/"
198 chars
7 lines

In this example, we use the Path.GetPathRoot() method to find the root directory of a path string "C:/Users/username/Documents/folder/file.txt". The method returns the root directory "C:/", which is then printed to the console.
