C# - Check if File is Text Based

Question

How can I test whether a file that I\'m opening in C# using FileStream is a \"text type\" file? I would like my program to open any file that is text based, for example, .t

I guess you could just check through the first 1000 (arbitrary number) characters and see if there are unprintable characters, or if they are all ascii in a certain range. If the latter, assume that it is text?

Whatever you do is going to be a guess.
