find the parent directory of a file in csharp

To find the parent directory of a file in C#, you can use the Directory.GetParent method or the Path.GetDirectoryName method. Here's an example using Directory.GetParent:


main.cs
string filePath = @"C:\myFolder\mySubFolder\myFile.txt";
string parentDirPath = Directory.GetParent(filePath).FullName;
Console.WriteLine(parentDirPath); // Output: C:\myFolder\mySubFolder
189 chars
4 lines

And here's an example using Path.GetDirectoryName:


main.cs
string filePath = @"C:\myFolder\mySubFolder\myFile.txt";
string parentDirPath = Path.GetDirectoryName(filePath);
Console.WriteLine(parentDirPath); // Output: C:\myFolder\mySubFolder
182 chars
4 lines

Both methods will return the full path of the parent directory of the specified file.
