Better way to check if a Path is a File or a Directory?

Question

I am processing a TreeView of directories and files. A user can select either a file or a directory and then do something with it. This requires me to have a method which performs different actions based on the user's selection.

At the moment I am doing something like this to determine whether the path is a file or a directory:

bool bIsFile = false; bool bIsDirectory = false;  try {     string[] subfolders = Directory.GetDirectories(strFilePath);      bIsDirectory = true;     bIsFile = false; } catch(System.IO.IOException) {     bIsFolder = false;     bIsFile = true; } 

I cannot help to feel that there is a better way to do this! I was hoping to find a standard .NET method to handle this, but I haven't been able to do so. Does such a method exist, and if not, what is the most straightforward means to determine whether a path is a file or directory?

Answer 1

From How to tell if path is file or directory:

// get the file attributes for file or directory FileAttributes attr = File.GetAttributes(@"c:\Temp");  //detect whether its a directory or file if ((attr & FileAttributes.Directory) == FileAttributes.Directory)     MessageBox.Show("Its a directory"); else     MessageBox.Show("Its a file"); 

Update for .NET 4.0+

Per the comments below, if you are on .NET 4.0 or later (and maximum performance is not critical) you can write the code in a cleaner way:

// get the file attributes for file or directory FileAttributes attr = File.GetAttributes(@"c:\Temp");  if (attr.HasFlag(FileAttributes.Directory))     MessageBox.Show("Its a directory"); else     MessageBox.Show("Its a file");

How about using these?

File.Exists(); Directory.Exists();
