How to create a stream from a string in .Net

• 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.
  

• 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
  

• 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"));
