Question

I have a function that reads a bunch of path-values (8 or 9 of them) from a text file. It uses these paths later in the application to read files. Whats the best way to check for validity of these file-paths. Can I do a single catch of some sorts?

Answer 1

You can use File.Exists and/or Directory.Exists is a path can be a directory.

static void Main(string[] args)
{
    List<string> paths = new List<string>{"C:\\path1.txt", "c:\\path2.txt"};
    bool allValid = paths.All(path=>File.Exists(path));
}
