Hello,

Does anyone know how to convert a String variable into a System.IO.StreamReader object ?

Thanks in advance,
Joe
 
StreamReader operates on files. I suppose you are looking for StringReader class.

Thanks for your reply Alex.

I have a Method processing XML. The XML originally came from a file but now I can also get the XML back from another Method as a String. I didn't necessarily want to create another Overloaded Method to handle the String but I guess I have no choice.

Maybe something like this will work for you.

Imports System.IO
Imports System.Text
....
Public Function GetSR(ByVal Input As String) As StreamReader
GetSR = New StreamReader(New MemoryStream(New
ASCIIEncoding().GetBytes(Input)))
End Function
 
| Imports System.IO
| Imports System.Text
| ...
| Public Function GetSR(ByVal Input As String) As StreamReader
| GetSR = New StreamReader(New MemoryStream(New
| ASCIIEncoding().GetBytes(Input)))
| End Function

Please note that this solution won't work if you string contains any
non-ASCII characters.

Thanks for pointing out the problem. So what is the solution Roman? Would
using UTF8Encoding be better than ASCIIEncoding?
 
Thanks Gordon and Roman.

The choice of encoding depends on what you want to do with resutling
sequence of bytes.
You can't tell that one encoding is "better" than other. If your original
string is known to contain only ASCII character (\u0000-\u007F), your
solution is fine. oll other characters will be replaced with '?'. But if
you want to encode arbitrary international strings without loss of
information, UnicodeEncoding or UTF8 encoding should be used. Please keep
in mind that every unicode character in the original string can be
represented by more than one byte in a resulting byte stream. In case of
Unicode encoding it's 2 bytes per unicode character (endianess is
important), in case of UTF8 it's variable length (1-4 bytes per Unicode
character).
