Use a MemoryStream with a function that expects a Filestream

I have some functions here that for example are defined as 

private int WriteLogikParameterTyp(FileStream filestream)

which i can not change. I want them to write into a MemoryStream Object. Is this possible?

Suggestion;

Rename the method like this

private int WriteLogikParameterTyp_Ex(Stream stream);

Then recreate the original signature like;

private int WriteLogikParameterTyp(FileStream filestream)
{
     return WriteLogikParameterTyp_Ex(filestream);
}

No. FileStream doesn't expose a constructor that can be called so you can't inherit from it in order to emulate it.

No.

If you do not have access to them, you could use reflector to find out how they work and implement your own version for a MemoryStream. Whether this is legal is another matter...

Since you can't change the function signature to accept a more generic type.. I'd suggest writing out to a temporary file and then reading the contents into a MemoryStream instance.

No.

FileStream is a concrete implementation.

But it's a private method so should be easy enough to change since you can find all internal uses? Suggest replacing method signature with Stream rather than FileStream.

Well... unless you create a tempory file, write to it then read it into memory.
