How to Convert Stream to String

• Mark Vernon

  Hi Vijil. Can you be more specific You say you want to convert a String to a String, then you show code that users a String and a Stream. Do you want to serialize a string

  Hi Peter,
       Your Previous sample
  
  Dim path As System.IO.Stream = (Reflection.Assembly. _
      GetExecutingAssembly().GetManifestResourceStream("vbnewsgrouptesting.notes.txt"))
  Dim bytes(path.Length) As Byte
  path.Position = 0
  path.Read(bytes, 0, path.Length)
  Dim data As String = Encoding.ASCII.GetString(bytes)
  
    
  Works fine when i assign  to webbrowser  like this.
  
  

  WebBrowser1.DocumentText = data

  Thank you.

  converting a Stream to String Was this post helpful

  Hi everyone, I'm having the same problem trying to convert a stream to String. But nothing seems to work. Here's my code: void displayImage(IO:tream^ imagePath) { array<Byte>^bytes = gcnew array<Byte>((int)imagePath->Length); imagePath->Position=0; int n = imagePath->Read(bytes,0,(int) imagePath->Length); System:tring^ path = System::Text::ASCIIEncoding::GetString(bytes); } but I'm getting the error : error C2352: 'System::Text::Encoding::GetString' : illegal call of non-static member function c:\windows\microsoft.net\framework\v2.0.50727\mscorlib.dll : see declaration of 'System::Text::Encoding::GetString' Does anyone know what I'm doing wrong. I've been spending about 2 days to convert the stream I get from my OpenFileDialog to string to show it. I've also tried System:tring^ path = System::Text::UnicodeEncoding::GetString(bytes); but I get the same error. I would appritiate any help. Thanks

  Hi Vijil. It depends on what you want to do and what type of stream it is. You don't "convert" a string to a stream, you usually serialize a string to a stream. For example:

  String text = "0123456789";

  using (Stream stream = new MemoryStream(100))

  {

  System.Runtime.Serialization.Formatters.Binary.BinaryFormatter binaryFormatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();

  binaryFormatter.Serialize(stream, text);

  }

  ...where you'd replace MemoryStream with a stream that probably persists to a storage device other than memory.

  Faced with the same problem, needing to get a string onto a stream, I found your posting and tried your method. It did not work for me and I was unable to figure out why. (I am very new to .net stuff.) The solution I ended up with seems a little clearer and simpler:
  
  String text = "0123456789";
  using (Stream stmText = new MemoryStream(text.Length))
  {
  StreamWriter swText = new StreamWriter(stmText);
  
  swText.Write(text);
  swText.Flush();
  
  stmText.Position = 0;
  
  // Use the stream
  }

  Dear Peter,

   

                       Thanks for the Quick replay and the solution. I  am very happy. I search the google and tryed myself past one day.

  Your answer is great. Your two line coding reduce my tension. Really  you are great.

   

  Now I am trying to convert the text file to pdf file. Could you tell me where I want post my query and get the result, and I am excepting some URL from you.

  It depends on the content of the stream whether or not you can conver to a string.

  What type of embedded resource are you trying to load from the assembly's resources with GetManifestResourceStream   If you're trying to load textual data, let's say you've embedded a resource from file "notes.txt" you would use the Stream's Read method to get the data as bytes then Encoding.ASCII to convert it to a string:
  

  Dim path As System.IO.Stream = (Reflection.Assembly. _     GetExecutingAssembly().GetManifestResourceStream("vbnewsgrouptesting.notes.txt")) Dim bytes(path.Length) As Byte path.Position = 0 path.Read(bytes, 0, path.Length) Dim data As String = Encoding.ASCII.GetString(bytes) Debug.WriteLine(data)

  Do you want to call WebBrowser.Navigate after the call to GetManifestResourceStream()
  
  If that's the case, just write the stream out to a temporary file and call Navigate; there's no need to fiddle with encoding.  Something like:
  

  System.IO.Stream inStream = (Assembly.GetExecutingAssembly().GetManifestResourceStream("WindowsApplication2.HTMLPage1.htm")); string path = Path.GetTempFileName(); FileStream fs = new FileStream(path, FileMode.Truncate); BinaryWriter w = new BinaryWriter(fs); byte [] bytes = new byte[inStream.Length]; inStream.Position = 0; inStream.Read(bytes, 0, (int)inStream.Length); w.Write(bytes); w.Flush(); w.Close(); Debug.WriteLine("Output " + bytes.Length.ToString() + " bytes to " + path); // TODO: WebBrowser.Navigate("file://" + path);

  
  
  Change Path.GetTempFileName() to something that generates a file path that you want.
