I need to convert a String to System.IO.Stream type to pass to another method.

I tried this unsuccessfully.

Stream stream = new StringReader(contents);

Try this:

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
//byte[] byteArray = Encoding.ASCII.GetBytes(contents);
MemoryStream stream = new MemoryStream(byteArray);

and

// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();

  • Thanks. I wasn't aware MemoryStream was the same as Stream. – xbonez Nov 08 '11 at 07:29

    @xbonez: `Stream` is not the same as `MemoryStream`. `MemoryStream` inherits from `Stream`, just like `FileStream`. So you can cast them as `Stream`... – Marco Nov 08 '11 at 07:31

    Just a note: Streams implement IDisposable, so you need a using wrapper around them to be safe. – Steve Hibbert May 23 '14 at 11:32

To convert a string to a stream you need to decide which encoding the bytes in the stream should have to represent that string - for example you can:

MemoryStream mStrm= new MemoryStream( Encoding.UTF8.GetBytes( contents ) );

System.IO.MemoryStream mStream = new System.IO.MemoryStream(System.Text.Encoding.UTF8.GetBytes( contents));

string str = "asasdkopaksdpoadks";
byte[] data = Encoding.ASCII.GetBytes(str);
MemoryStream stm = new MemoryStream(data, 0, data.Length);

this is old but for help :

you can also use the stringReader stream 

string str = "asasdkopaksdpoadks";
StringReader TheStream = new StringReader( str );
