Do you mean something like the System.IO.StringReader class ?

Nighogg,
Thanks that will actually work for what I'm doing, because there is a overload that takes a TextReader. I don't know how I overlooked that before, I guess I was too focused on getting a stream.

However StringReader doesn't produce a stream, at least I don't see any easy method to create a stream from it. So I'm still curious to see if there is a better method of creating a stream from a string.

There is no other conceptual way. A stream is a series of bytes. You decide what encoding you want to use (usually not ASCII, but UTF-8 or windows-1252) and you convert it to a series of bytes. Your code is about the most concise and efficient way to do that.

If you just need to get your string *into* an existing stream (a file stream, etc), you may choose to use a StreamWriter instead (which still needs you to tell it what encoding to use).

Thanks Erv,

I didn't realize it until you mentioned it but ASCIIEncoding inherits from Encoding and the Default property actually calls GetACP underneath which will get the codepage from the system, which should work in most cases.

As far as what I was doing I needed to create a new stream to send as a parameter to a method (ReadXML on a DataSet object). It turns out that it also had an overload that took a TextReader so I just used that instead.

May want to consider UTF8 encoding instead of ASCII (7-bit).

Very useful, you've just saved me an hour trying to figure out how to do this.

Thanks for posting, works great

Works Perfect...

Thankz a lot!..

If you have a string stringVal then use

StringReader strReader = new StringReader(stringVal);

StringReader is descendent of TextReader and in turn Stream class.

Avinash: TextReader derives from MarshalByRefObject, not Stream.

See msdn2.microsoft.com/.../system.io.textreader.aspx

If all you're trying to do is create a XmlTextReader and all you have is a string, this is the easiest way to do so:

XmlTextReader reader = new XmlTextReader(new StringReader(xmlString));

no TextReader is not a Stream

Thanks - this was a great little bit of help and saved me hunting around the web for a few hours

Never, ever use ASCIIEncoding.Default!!! But thanks for your post, thats how I got aware ;-)

Try using StringReader()

public static class StringExtensions

{

public static MemoryStream ToMemoryStream(this string source) {

return source.ToMemoryStream(ASCIIEncoding.UTF8);

}

public static MemoryStream ToMemoryStream(

this string source, Encoding encoding)

{

return new MemoryStream(encoding.GetBytes(source));

}

}

Stream s = new MemoryStream(ASCIIEncoding.Default.GetBytes("Test String"));
