Parsing an arbitrary file path as a Uri or similar

Hello there. I would like to be able to parse the following inputs in such a way that I'm aware if they are a relative or absolute path:

path/to/file.txt -> "Relative"
/path/to/file.txt -> "Absolute"
./path/to/file.txt -> "Relative"

path/to/file.txt -> "Relative"
/path/to/file.txt -> "Absolute"
./path/to/file.txt -> "Relative"

I'm having trouble getting this to work with Uri.TryCreate(). they all return false for their IsAbsoluteUri properties, when at least the second one should be true. I'm not sure what properties or methods I should utilize to obtain the information I'm after. Any pointers/tips?

Idk how to make modix show the output but this should work It'll return true for absolute paths

Neat, that does seem to work. I actually realized, this is pointless. File.ReadAllText already supports relative paths, so these three examples work right out of the box. I had a feeling I was overthinking things. whenlifegetsatyou
