reading files in c#

".x files are animation files.
i need to read that .x files.
in that .x files i have different name of methods.
i want read only one method in that file.
what i am reading file should be stored in another .x file"

First of all, don't post an answer unless you're posting an answer. Edit your post to add details.

What do you mean, they contain 'methods' ? Either way, to do this, you need to learn how the .x file format works, whatever that is. To read the file, use File.ReadAllBytes, but C# is going to give you the file contents, YOU need to write code to interpret that file and get the information you want in a format that is useful to you.

I just Googled this[^] and there are a number of references to .X file formats on the web. I suggest you try the same and go from there. Note, having browsed one of the file descriptions I think this is a non-trivial exercise, you may be better searching for a library that supports access to these file types.
