Which FileShare option is used with FileInfo.OpenRead method?

Question

On .NET Framework documentation says that when I use FileInfo.OpenRead method a read-only FileStream is created but, which FileShare option is internally used?

Once I've opened the file is read or write locked?

A quick look in reference source reveals that it is

FileShare.Read

This setting is documented to

Answer 2

As per the documentation:

This method returns a read-only FileStream object with the FileShare mode set to Read.
