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, .txt, .html, etc.
But not open such things as .doc or .pdf or .exe, etc.

C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
Compared to other languages—like Java, PHP, or C#—C is a relatively simple language to learn for anyone just starting to learn computer programming because of its limited number of keywords.
C is an imperative procedural language supporting structured programming, lexical variable scope, and recursion, with a static type system. It was designed to be compiled to provide low-level access to memory and language constructs that map efficiently to machine instructions, all with minimal runtime support.
Full form of C is “COMPILE”. One thing which was missing in C language was further added to C++ that is 'the concept of CLASSES'.
In general: there is no way to tell.
A text file stored in UTF-16 will likely look like binary if you open it with an 8-bit encoding. Equally someone could save a text file as a .doc (it is a document).
While you could open the file and look at some of the content all such heuristics will sometimes fail (eg. notepad tries to do this, by careful selection of a few characters notepad will guess wrong and display completely different content).
If you have a specific scenario, rather than being able to open and process anything, you should be able to do much better.
