StreamReader to read from string?

[Guest]

Hi,

Im using a code snippet that reads a text file from disc and processes it
using

stream = new StreamReader(filename);

Is it possible to assign a String instead of a file as the source of the
stream, and if yes, how?

Regards
Jesper.

Well, not for a StreamReader (easily) - but if all you need is a
*TextReader* (which is probable) just use StringReader instead.

Hello,
Yes you can, convert the string in to byte array using
System.Text.Encoding.ASCII.GetBytes method. Then pass those bytes to
MemoryStream class's constructor. You'll get and Stream object, but it
won't be of 'StreamReader' type.

HTH. Cheers.

Something like this:

string text = "hello streams";
StreamReader reader = new StreamReader (new MemoryStream (
System.Text.Encoding.ASCII.GetBytes (text )));

That's a really bad idea unless you've got solely ASCII characters.
You should at least use something which preserves Unicode characters -
eg Encoding.UTF8. (That also happens to be the default encoding used by
StreamReader...)

Hello,
Yes, it was just to *tell* it all depends upon the requirements of
the problem.

Unfortunately, in my experience if you specify a "solution" which
doesn't explain its own limitations, people tend to use it without
questioning whether or not it's actually fit for purpose
